                                           PART 1 - GENERAL

1.1     Outline of Work

1.1.1       The scope of work required under this section of the specifications includes for the complete
            removal of any Asbestos-containing building materials found in the specific area of the St.
            Raphael Catholic Elementary School located at the civil address of 33470 Clara Drive in
            Mississauga, Ontario

1.1.2       This is a renovation project and protection of the building, its components and finish is
            required

1.1.3       No suspect asbestos-containing materials shall be removed or disturbed until sampling and
            analysis is performed by NORROX Technical Services Inc.

1.1.4       Asbestos is suspected in the following building materials:

1.1.4.1                   Cores in Fire-rated Doors - The core material that may be present in select wood
                          and metal doors may contain asbestos. Access to the interior of the doors prior to
                          construction is not possible as breaking or drilling the exterior of the door for
                          sampling may void the UL or ULC fire rating. The doors should not be disposed
                          of if removed until sampling confirms the status of asbestos in the doors.

1.1.4.2                   Cement Pipe – Asbestos-containing cement rainwater leader and drain pipe may
                          be present under the finished flooring of the building and may also be present
                          associated with drainage pipe, between catch basins about the site. Original
                          construction specifications permitted the use of asbestos cement pipe. Existing
                          drain pipe found above grade in the building were copper and cast iron.

1.1.5       Allow NORROX Technical Services Inc. to sample the above noted material prior to removal
            or disturbance.

1.1.5.1                   Doors may be removed by popping the hinge pins and placing them aside for
                          sampling and analysis

1.1.5.2                   Floors shall be opened by the General Contractor or sub-trade and excavated
                          exposing underground piping

1.1.6       If any of the above noted materials contain asbestos, NORROX Technical Services Inc. will
            provide further instruction with respect to work procedures, waste disposal and matters
            relating to worker safety.

1.1.7        Payment shall be negotiated in writing prior to the removal of any confirmed Asbestos-containing
             Materials.

The following substances: Lead, Mercury and Silica have been identified in the select area of the school
building and are further detailed in this report. It should be noted that asbestos was not identified in any
accessible building materials but is suspected to be present in cement drain or rainwater leader pipe found
under the finished floor, in the cores of metal and wood doors and as packing and gasket in hot water heating
pipe fittings and flange joints. Minor demolition would be required to access these materials.



Asbestos

A - Materials Identified to Contain Asbestos in the Designated Section of the Building Investigated
Asbestos was not identified in any of the building materials found in the designated section of the building
that was investigated.

        Friable Material - The installation of friable asbestos-containing materials were banned after 1986
        under Ontario Regulation 654/85. No friable asbestos-containing materials were found in the
        designated section of the building that was investigated.

        Non-friable Material - Non-friable material can still be purchased in today’s market with the
        exception of any products containing Crocidolite. The handling of these products must follow type 1,
        2 or 3 procedures depending on the method the material is handled. No actual asbestos-containing
        materials were identified in the designated section of the building that was investigated. However,
        several materials are suspected to contain asbestos. Refer to “B – Materials Suspected to Contain
        Asbestos” in the following.

B - Materials Suspected to Contain Asbestos in the Designated Section of the Building Investigated
No additional materials were found in the designated section of the building that was investigated was
suspected to contain asbestos.

•       Cores in Fire-rated Doors - The core material that may be present in select wood and metal doors
        may contain asbestos. Access to the interior of the doors is not possible as breaking or drilling the
        exterior of the door for sampling may void the UL or ULC fire rating. The doors should not disposed
        of if removed until sampling confirms the status of asbestos in the doors.

•       Cement Pipe – Asbestos-containing cement rainwater leader and drain pipe may be present under the
        finished flooring of the building and may also be present associated with drainage pipe between catch
        basins about the site. Existing drain pipe found above grade in the building were copper and cast iron.

•       Gasket and Packing – The gasket and packing in hot water heating pipe fittings and in flange joints
        may contain asbestos. Even if original material was asbestos free replacement material may contain
        asbestos.

C - Materials That Do Not Contain Asbestos in the Designated Section of the Building Investigated
Asbestos was not identified or suspected in the following materials in the designated section of the building
investigated. Any materials found in the designated section of the building found in the room space, above
suspended ceilings and in millwork as described in this section does not contain asbestos.

        Friable Material

•       Thermal Insulation Applied on Pipe and Duct – The fibrous glass or mineral wool type
        applications readily identified by either a distinct yellow or pink color do not contain Asbestos.

        Non-friable Material

•       Acoustical Suspended Ceiling Tile – Two types of acoustical suspended ceiling tiles of the lay
        above type were found in the various rooms of the designated section of the building investigated
        were confirmed by analysis, not to contain asbestos. The ceiling tiles were manufactured by
        Armstrong Industries and was identified by labeling printed on the back of the tile. These tiles had
        respectively a random fissure pattern or an irregular dot pattern on the finished surface of the tile and
        were of the 895 brand or Resistive brand. Four samples of the first tile brand and three of the seconc
        was selected and confirmed by analysis to not contain asbestos. Although the tiles do not contain
        asbestos they may contain silica in a variety of ways as Mineral Wool, Perlite, Diatomaceous Earth or
        as Quartz.

•       Vinyl Composition Floor Tile - All applications of vinyl floor tile found in the designated section of
        the building were confirmed to contain trace levels of Chrysotile asbestsos, however the
        concentration was less then 0.5 %. The tile exhibited a similar mottled pattern with a cream or brown
        coloration and were of the 12" x 12" in size. There were no stock supplies of the tile. Three samples
        of the tile was collected from Classroom 105 and were all analyzed by transmission electron
        microscopy. In addition under Ontario Regulation 278/05 if the owner can confirm by manufacturers
        literature or material safety data sheets that Asbestos is not present, sampling would not be required.

•       Plaster Joint Filling Compounds – There is a limited amount of this material found in the two
        classrooms respectively applied to a common partition wall between classrooms 104 and 105. The
        plaster joint filling compound was applied to gypsum drywall panels. Three samples were collected
        and analysis confirmed that this material does not contain asbestos

•       Caulking – Caulking was applied around door and window frames. The caulking was similar in color
        and texture. Three samples were collected from each of the original building and building addition
        and analysis confirmed that these materials do not contain asbestos.

Lead

In general the concentration of lead in paint films was slight in the designated sections of the building that
was investigated as the treatment of Sodium Sulphide produced a slight black precipitate on the painted
surfaces. It should be concluded that lead may present in the painted surfaces but in very low concentrations.
Applications such as paint on structural steel were not tested, as it would be expected for the paint to contain
in the order of 80% lead in the solids. Exterior surfaces were also not tested as these were out of the specified
area of the building requiring investigation but expected to have a higher concentration of lead.

The regulations in Ontario are not limited to lead in paint alone. As such it is prudent to assume that lead is
present in the following observed building materials;
    • As a component of the solder on sweated on joints between copper pipe and fittings including
        domestic water supply pipe;
    • As a component of the solder on wire connections of electronic components;
    • As a component in the lead acid storage batteries found in the emergency lighting; and
    • As a component of the fuse link in the fire dampers.



Assessment of Lead in Lead-based Paints

All painted films were found to be intact with only minor chipping observed. No recommendations for further
action are required.

The presence of lead in building finishes left intact or found peeling in a few locations as is this case is not
expected to produce substantial exposure for workers to lead through contact, inhalation or ingestion. Actual
exposure although expected to be low is not within the scope of this assessment and can only be appraised by
air monitoring.

Any operation involving lead-based paints may potentially produce significant exposures to lead if adequate
controls are not provided. Exposure varies with the type of operation being employed.

Assessment of Lead Solders
Water Pipe and Electronic Equipment

Lead found in solder of pipe systems including water supply and lead found in solder in electronic
components poses no threat to the work force from occupancy by inhalation, ingestion or by contact with the
exception of maintenance activities that would result in heating the lead solders. The maintenance of the pipe
or electrical component may produce some exposure to lead fume during the sweating on of lead solders but
for a short duration of time. Inhalation is the source of entry and exposure is not very significant for short
duration work.

Mercury

No samples were taken for mercury however based on the age of the building and the common use of
Mercury at this time it is presumed to be present in the following materials:

    •    As a gas in the observed florescent light tubes found in service throughout the areas of the building
         investigated; and
    •    As a bactericide or stabiliser in paints or caulking for all building sections.

Assessment of Mercury

A - Mercury in Florescent Light Tubes

Florescent light tubes contain small quantities of mercury gas. These sealed units do not pose any harm in the
workplace except in the case of breakage. There are no liquid or residue present after breakage and spill
cleaning is not a concern. A recommended practice is to evacuate the work area when breakage occurs. The
gas will diffuse in about five to ten minutes and cleanup of the tubes can be performed. Mercury can be taken
into the body by inhalation only from this source.

B - Mercury in paints

The same precautions as those indicated for lead-based paints would apply to mercury in paints.


Silica

No samples were taken specifically for silica, however mineral wool, fibrous glass, ceramic fibre and quartz
were identified with the asbestos analysis and are all forms of silica. Additionally it is presumed to be present
in cement, cement blocks, bricks and mortar of the building. All these forms are not in respirable size and not
readily released in the building's air.

Assessment of Silica

Unless the silica in the specified materials is reduced to respirable size (5 um or less) and the airborne
concentration exceeds the time weighted average exposure of 0.2 milligrams per cubic metre in air, no
adverse health effects are expected to occur. Building construction, renovation and demolition do not
normally raise excessive exposure to silica. There is little likelihood for the work force to be exposed to
excessive levels of respirable silica dust if the material is suppressed with water spray.

1.0     INTRODUCTION

NORROX Technical Services Inc. was retained by the Dufferin-Peel Catholic District School Board
through Hossack & Associates Architects to carry out a hazardous material audit comprising of a
designated substance audit including Asbestos of a select area in the St Rapheal Catholic Elementary
School building. A designated substance audit is required under the Ontario, Occupational Health and
Safety Act to develop or renovate a site and to present a list of designated substances to a Contractor and
sub-trades prior to the tendering or offer of work on a construction project.

Messrs Norman Chudzinski & Matthew Chudzinski of NORROX Technical Services Inc. performed the
audit of the select location of the building on December 10, 2010. The school building is located at the
civil address of 3470 Clara Drive in Mississauga, Ontario.

The survey entailed:

•       An inspection of accessible areas of the building in two separate classrooms (104 & 105)
        including the adjacent hall on the first floor to identify materials which could contain asbestos or
        other designated substances;

•       Bulk sampling and analysis of representative materials suspected of containing asbestos;

•       An assessment of the condition of any asbestos-containing material with recommendations for
        appropriate corrective action where required;

•       An assessment of the likelihood of exposure to any other designated substances with
        recommendations for appropriate corrective action where required; and

•       A report detailing the findings of the survey.

The purpose of this survey is to form the basis of a Designated Substance Program for renovations
intended in the washroom. Information on the locations of the various substances found in the select areas
of the building as presented in Section 4 of this report shall be provided to all prospective contractors (and
in turn to their sub-trades) who are likely to handle or disturb the material and to employees of the
building, who may work in close proximity to the material and who may also disturb the materials.

This report is provided for the two select areas of the building, highlighted in Section 4 of this report.
Any areas of the building outside the boundaries of the areas of the building investigated for this
report must be audited in accordance with the requirements of Ontario Regulation 278/05 prior to
performing any construction, service or maintenance operations or activities.

The information provided in this document should be updated when materials are removed or when
concealed materials have been disclosed.

The following substances: Lead, Mercury and Silica have been identified in the select area of the school
building and are further detailed in this report. It should be noted that asbestos was not identified in any
accessible building materials but is suspected to be present in cement drain or rainwater leader pipe found
under the finished floor, in the cores of metal and wood doors and as packing and gasket in hot water
heating pipe fittings and flange joints. Minor demolition would be required to access these materials.



1.1     REPORT OUTLINE

The report is structured as follows:

Section 2 - REGULATORY FRAMEWORK; gives a list of regulations dealing with designated
substances and their disposal. Should the regulations be amended then this section should be changed
to reflect the new status.

Section 3 - BACKGROUND INFORMATION ON DESIGNATED SUBSTANCES INCLUDING PCBs
AND OZONE DEPLETING SUBSTANCES; provides an overview on each substance; its properties,
uses, and health affect due to exposure.

Section 4 - HAZARDOUS MATERIALS SURVEY; covers the building inspection and sampling
methodologies, results, and assessment of exposure. It should be noted that the condition of friable
asbestos-containing materials and non-friable material must be assessed on a periodic basis. For friable

3.0     BACKGROUND INFORMATION

The following information in this section provides a brief description of what the designated substances
are, where they are found and what is the health hazard with each substance.



3.1     ACRYLONITRILE

Acrylonitrile is a clear, colourless, highly flammable, volatile liquid. It may also be found in the vapor
(gaseous state) in the workplace. Acrylonitrile is employed as a monomer that reacts with other chemicals
to produce polymers such as resins.

They are used in the production of nitrile rubbers, Plastics, acrylic and monoacrylic fibres, synthetic soil
blocks, cyanoethylation of cotton bottles for soft drinks, coatings and adhesives. Industries, which use
these products, include automotive parts, clothing, carpets, plastics and gasket manufacturing.

Workers may be exposed to acrylonitrile through inhalation and through ingestion. Skin contact can cause
itching and rashes. Diseases associated with acrylonitrile exposure include cancer and acute acrylonitrile
poisoning (which may be fatal). Symptoms of acute acrylonitrile poisoning include headaches, nausea,
diarrhea and vomiting.



3.2     ARSENIC

Arsenic is a heavy metal found in low concentrations in the earth's crust. It may be used in elemental form
or as a chemical compound. The most common form if this element is a grey, brittle crystalline solid
substance. Elemental or metallic arsenic is employed as an alloying agent for heavy metals in special
orders and as a doping agent in silicon and germanium solid state products. Those principally exposed to
arsenic in industry include metal workers, refiners (in particular copper refining) petroleum refiners and
with herbicide manufacture. Exposure is generally via inhalation. Chronic effects or arsenic and its
compounds include lung cancer, blood disorders, heart failure, bronchitis and laryngitis. Acute effects
include pulmonary neoplasms of bronchitis.



3.3     ASBESTOS

Of the approximately thirty naturally forming fibrous minerals found in the world, there are only six
forms that are considered to be Asbestos. These minerals are found in every mountain formation through
out the work, in both fibrous and crystalline forms. Typical of all Asbestos minerals, is the ability to

separate the fibrous rock into long fibres that can be further separated into finer and even finer
microscopic fibrils.

The Asbestos minerals are divided into two broad geological mineral groups, serpentine and amphibole
fibrous minerals. Chrysotile is the only representative of the Serpentine group and the only type of
Asbestos that can be woven into cloth. The remaining five type of Asbestos: Amosite, Crocidolite,
Anthophilite, Actinolite and Tremolite all belong to the Amphibole group, which are characterized by the
fibres needle-like appearance. Of all size types of fibrous minerals Chrysotile was the most predominant
with Amosite and Crocidolite used to a lesser extent. The presence in building materials of Anthophilite,
Actinolite and Tremolite is even less prevalent.

There are over 3,000 separate uses of Asbestos identified in the literature. Each use is dependent on the
particular unique physical and chemical properties of each type of Asbestos. The desirable properties
include:

        Fire retardance                            Resistance to acids and alkalies
        High tensile strength                      Thermal insulation
        Reinforcement                              Friction and wear resistance
        Spinability                                Cohesion

Asbestos is rarely found in pure form in most building products and type of Asbestos used is dependant
on application.

Asbestos-containing products are divided into two broad categories based on the materials hardness and
are termed friability. Friable materials are defined as materials that, when dry, can be crumbled,
pulverized or powdered by hand pressure and includes such materials. Non-friable materials are generally
hard and do not readily release fibres. In general a specific Asbestos-containing material is referred to as
either a friable; or non-friable material. No friable materials however may include manufactured products
that are installed of removed intact even though these materials meet the definition of friable materials.
The following materials under the Asbestos Regulation are classified as either friable or non-friable
material:

Friable Materials
        Fireproofing     Thermal Insulation        Refractory       Acoustical Textured Materials

Non-friable Materials
       Cement products            Felts Cloths              Floor coverings          Friction products

HEALTH EFFECT OF ASBESTOS

Asbestos fibre has been shown to be associated with the development of a variety of diseases. Exposure to
Asbestos is gained primarily through the inhalation of the fibres where they become trapped in the lungs.
It is not clear how the Asbestos fibres cause disease. However there is strong evidence that is the long and
very thin fibres that are associated with disease. The three principle respiratory diseases include:

        Asbestosis:               A chronic dose related disease;
        Lung Cancer:              A cancer of the lower respiratory tract; and
        Mesothilioma:             A cancer of the gut cavity.



ASBESTOSIS

A chronic lung disease caused by scar tissue forming around very small Asbestos fibres deposited in the
lower respiratory tract. The scar tissue affects the ability of the lungs to expand and contract, as well as
limiting the surface area for gas exchange. Often fluid fills the affected lung tissue, where cracks and rales
can be heard through a physician's stethoscope. The resultant effect is shortness of breath and can lead to
other complications such as stroke and hear attack. This disease is dose related, irreversible and will
continue to progress even after exposure has stopped.

LUNG CANCER

Lung cancer is typically an uncontrolled growth of tissue. Exposure to Asbestos fibre is one of many risk
factors associated with the development of lung cancer. The cancer due to Asbestos exposure arises from
the lower respiratory tract. The risk in developing lung cancer is five to ten times greater for those who
are not exposed to Asbestos and increases to 50 to 90 times greater to those exposed to Asbestos and
smoke. Life expectancy after diagnosis can be as little as five years after first diagnosis.

MESOTHELIOMA

Mesothelioma is a rare cancer of the lining of the chest and/or abdomen. This disease occurs when
resilient Asbestos fibres have penetrated through the lungs in the body cavity. It is a rapidly progressing
disease and is usually fatal within a year of diagnosis. Although other materials have been identified to
cause this disease Asbestos is still the major cause.

LATENCY OF DISEASE ONSET

All the three fore mentioned diseases exhibit a long latency period between initial exposure and disease
onset. Asbestosis can occur within 10 years of exposure while lung cancer can occur within 10 to 15
years. Mesothelioma can occur between 20 and 40 years.

OTHER RELATED CANCERS

There is some evidence of an increased risk of cancer of the stomach, colon, rectum and larynx in persons
exposed to Asbestos, however the link between Asbestos exposure and these particular cancers is not as
clear as with lung cancer or Mesothelioma.

OTHER RELATED CONDITIONS

The following conditions are not associated with serious Asbestos related disease but serve to indicate
past exposure. They are as follows: pleural plaques (scarring of the chest lining), Asbestos bodies in the
lung or Asbestos warts on the skin.



3.4     BENZENE

Benzene is a colourless, highly flammable and volatile aromatic organic hydrocarbon. Although used in
liquid form, it may be present as a vapor. Benzene is a by-product in the refining of petroleum and is
usually found in gasoline and other hydrocarbon fuels and products. It is also used in the manufacture of
styrene rubber, adhesives, sealants, paints, paper coatings, detergents, plastics and various organic
solvents.

Exposure to Benzene is primarily the result of breathing its vapors and mists. Liquid Benzene can also be
absorbed through dermal contact and ingested. This may result in eye, skin or throat irritation. Benzene
exposure may include the onset of Leukemia, and may affect the blood forming system, particularly bone
marrow.



3.5     COKE OVEN EMISSIONS

Coke Oven Emissions are the result of gasses created by the combustion of bituminous coals. There is no
singular type of gas emission but include a multitude of exposures partly dependent on the coal type and
process involved, and from complete and incomplete combustion. The principal industries involved
include smelting and thermal electrical generating plants.

Inhalation of the discharged gasses in coke plants lead to various types of lung cancers.



3.6       ETHYLENE OXIDE

Ethylene Oxide is a colourless gas with an ether-like odor at room temperature and pressure. Ethylene
Oxide may be used in the gaseous state or compressed as a liquid. It is a major chemical used largely in
the production of ethylene glycol for automotive antifreeze, in the polyester industry and for the
production of detergents.

Exposure can occur through inhalation, ingestion and by dermal or eye contact. Short-term exposure to
Ethylene Oxide can cause nausea, headache, weakness, vomiting, and drowsiness, in co-ordination and
irritation of the eyes, nose, throat and lungs. Skin contact with Ethylene Oxide can cause blisters, eczema,
burns, frostbite and severe dermatitis. Long term exposure to ethylene oxide can cause skin sensitization,
numbing of the sense of smell and respiratory infection.



3.7       ISOCYANATES

Isocyanates are a class of chemicals used in the manufacture of certain plastics, coatings, foams and other
products. They may include:

•     Methylene Bisphenyl Isocyanate (MBI): which exists as white to light-yellow, odorless flakes;
•     Toluene-2, U-Diisocyanate (TDI) which is a liquid at room temperature with a sharp pungent odor;
      and
•     Hexamethylene Diisocyanate (HDI) which is also a liquid.

These Isocyanates contain a group of atoms as (-NCO) which readily react during chemical process. They
may be found in liquid form (colourless to pale yellow or dark brown and viscous) or solid form (white or
yellow in colour). The following industries and processes use Isocyanates as follows;

•     MDI in foams, sealant and coatings;
•     TDI in polyurethane foams elastomers and coatings;
•     HDI in urethane products; and
•     Other uses such as soft synthetic rubbers, adhesives, insulation, packaging, paint hardeners, printing
      inks, foundry core binders, wire varnish and textile finishing.

Exposure to Isocyanates may occur from the inhalation of vapors, mists or dust. This may cause eye, nose
or throat irritation. Liquid Isocyanate can damage the skin or eyes on contact. However, they are not

absorbed into the body through dermal contact. High exposure can cause chest tightness, bronchitis,
bronchospasm, fluid in the lungs and asthmatic attacks. Other health risks include skin sensitization,
rashes and temporary decrease in sharpness of vision.



3.8       LEAD & LEAD IN PAINT

Lead is a metallic element in-group IV B of the periodic table. It is heavy and ductile which appears pale,
silvery-grey in colour when freshly cut, but darkens when exposed to air. Lead occurs naturally and is
widely distributed all over the work in the fork of its sulphide, the ore galena. Lead rank about 36th in
natural abundance among elements in the earth's crust.

Lead used in its metallic form or combined chemically finds wide industrial use due to its properties of
high density, softness, low melting point and resistance to corrosion. Lead in the work environment may
be distributed through lead containing dust, fumes, mists, liquids and as vapors of liquid organic lead
compounds. Industrial uses of Lead include; smelting and refining, electroplating, paint manufacture,
paint appliers and by various chemical manufacturers.

Lead was used extensively for pigmentation and as a drying agent up until the early 1950's in oil paints.
In the early 1950's other pigment materials became more popular, but lead compounds were still used in
some pigments and as drying agents. Exterior paints contained the highest levels: Up to 60 or 70 percent
lead by weight.

In 1973 the United States Consumer Product Safety Commission (CPSC) established a maximum lead
content in paint of 0.5% or 5,000 parts per million by dry weight in a newly applied film of paint. Also, in
the mid-1970's, the Canadian government also adopted this limit for interior paints. For the Canadian
environment, no limit was set on exterior paints, although that exceeding the 5,000 PPM limit is required
to have a label clearly stating: "Caution: Contains Lead. Do not apply to surfaces that children may
chew." Currently the majority of paints on the market conform to this U.S. standard. Since adoption of the
initial standard various bodies in the U.S. have lowered the standard most notably in 1978 the CPSC
lowered the level to 0.06% and the U.S. Food and Drug Administration recommends that the lead
concentration in house paints not exceed 0.05%.

In general humans are exposed to lead from numerous sources, such as paint fragments, auto and
industrial emissions and through water. Lead or lead compounds may be inhaled, ingested or absorbed
through the skin. Various body functions can be affected by lead or Lead compound. The various body
systems that can be affected by lead include:

      Blood - Lead interferes with the ability of the body to manufacture haemoglobin in the blood;

    Kidneys - It reduces the kidney's ability to filter wastes from the blood stream and in the
    gastrointestinal tract and may result in abdominal pain, loss of appetite, vomiting, nausea,
    constipation and diarrhea; and

    Nervous System - It can cause behavioral changes, impaired vision, hearing, brain disorders and
    peripheral nerve damage causing convulsions, coma and death.

From a health point of view for adults, dry lead-based paint that is intact poses little, if any hazard. The
hazard arises when the lead paint is disturbed in some way. Loose flakes of paint may occur as older
painted surfaces deteriorate and wear. The potential for exposure to lead is low since the flakes can only
enter the body if they are ingested. A greater potential for exposure to lead occurs during the sanding,
grinding or cutting of materials or surfaces covered in lead paint. In these cases, the lead-containing dust
can be inhaled. The heating of painted surfaces or materials creates the greatest potential for inhalation of
lead in the form of very small fume particles.

In adults, short-term or systemic exposure to lead may cause temporary illness but the effects are not
permanent. However, long-term or acute exposure can cause serious health problems for adults such as
kidney, nerve, hearing and vision damage.

While adults may suffer various ailments due to excessive lead in their blood, the groups most at risk
from exposure to lead are fetuses (through pregnant women), infants and children under seven. Children
also tend to absorb lead more easily than adults do because their metabolism is faster. Lead affects the
child's developing nervous system by slowing development. Children are particularly vulnerable up to the
age of six. The effects include hearing impairment, behavioral problems and a lessening of intelligence.

The signs of lead poisoning are difficult to distinguish from normal childhood complaints and sometimes,
children show no symptoms at all. When they do, the symptoms tend to be flu-like: stomach cramps,
irritability, loss of appetite and general fatigue. Because these symptoms are so general, it's best not to
rely on them as indicators of exposure. The only way to confirm lead poisoning is by clinical tests such as
blood or urine analysis.

Lead is excreted very slowly from the body. Treatment of lead poisoning includes the administration of
EDTA a chelating agent. The lead is removed from the body by displacing the calcium with lead in
EDTA and forming a stable complex that is excreted from the body in urine. Removing the excess lead
concentrations will lessen further damage to the body organs and blood.

3.9     MERCURY

Mercury a heavy metal in Group II B of the periodic table. It is an odorless, silvery coloured heavy liquid
with high surface tension at room temperature. It exists in pure elemental form, organic mercury
compounds and as mercury salts. Metallic mercury if used in the following products; batteries, electrical
equipment; florescent, neon and mercury vapor light tubes or bulbs; amalgam; electroplating; and in
thermometers, barometers and manometers. Mercury is used in liquid form, but may also be present as a
vapor in the work places that have these products. Mercuric compounds are found in the following
industries; paint manufacture, dye and ink manufacture, ceramic manufacture, explosives and fireworks
manufacture, paper manufacture, photography processing, pesticides manufacture and use, vinyl chloride
production and urethane foam production. Mercury compounds may be found in liquid or solid form
including dust particles for these industries.

Mercury exposure may occur when inhaled ingested or absorbed. Mercury poisoning can damage the
nervous system, kidneys, skin, respiratory system, reproductive system and gastrointestinal system.



3.10    SILICA

Silica is a colourless, odorless, transparent form of silicon dioxide (SiO2). It is found naturally in the free
crystalline form or as an amorphous material. Free crystalline silica is not bounded with a metal atom. It
occurs naturally as quartz and in combination with clays, feldspars and other silicates. Quartz alone
constitutes 30% of the earth's crust. Silica is used in several different industries and processes, such as
sandblasting, mould casting work and in foundries, in the manufacture or use of abrasives and grinding
compounds, fibrous glass manufacture, steel industries and quarries.

The primary exposure pathway of silica is through inhalation. A lung disease "Silicosis" is a result of the
scarring of lung tissue from exposure to the crystalline form of silica.



3.11    VINYL CHLORIDE

Vinyl chloride is a member of a group of chemicals referred to as vinyl halides. It is a colourless, highly
flammable gas with an ethereal odor at standard room temperature and pressure. It is usually handled as a
liquid under pressure and containing a polymerization inhibitor (phenol). The chief use of Vinyl chloride
is in the manufacture of polyvinyl chloride resins and in the production of ethylene oxide as an extraction
solvent. This material may be used in its vapor form or solubilized in a liquid.

Exposure may occur through inhalation, ingestion and dermal or eye contact, Short term exposure to vinyl chloride
can cause dizziness, drowsiness, light-headaches, nausea, dullness of visual and auditory responses and

4.0     DESIGNATED SUBSTANCE SURVEY

Information in this section of the report shall be provided to all prospective contractors (and in turn to their
sub-trades) who are likely to handle or disturb asbestos or other designated substances and to employees of
the building who may work in close proximity to these materials and who may disturb the material. This
report is provided for select areas of the building, as highlighted in this Section 4. Any areas of the building
outside the boundaries of the area of the building investigated for this report must be audited in
accordance with the requirements of Ontario Regulation 278/05 prior to performing any construction,
service or maintenance operations or activities.

This information will require updating if corrective measures have been instituted and materials have been
removed from various sections of the buildings or after demolition or renovation a close out report stating that
the materials are no longer present.

Destructive methods were not employed in the performance of the building audit and it is possible that
asbestos, or other designated substances could be present in areas not accessible to the surveyor for
identification. Contractors and maintenance personnel should be warned of the possibility of undisclosed
materials when breaking into enclosed areas. Specific building materials discovered in these areas should be
treated as asbestos-containing until proven otherwise and other substances self evident as a designated
substance should be handled in a likewise fashion.


4.1     SURVEY METHODOLOGY

The survey of a section of the building for designated substances consisted of a walk through and physical
examination of suspect materials in all accessible areas within the designated sections of the building that was
investigated. No destructive examinations were performed as part of this survey. The physical examination is
performed in order to assess the condition of material or to examine for underlying layers. The use of layout
floor plans was an integral part of ensuring all specified areas of the building have been examined. In
situations where friable asbestos-containing materials extend into a non-accessible area, it would be assumed
the asbestos-containing materials would also be present in these areas and reported as such.

Accessible is defined as an area above suspended ceiling tiles, behind a closed door or within an access hatch
not impeded by any permanent structure, article or thing. An area enclosed by building structures such as
gypsum wall board, plaster, solid lumber, cement blocks or bricks where minor demolition is required to gain
entry is considered non-accessible

Observations were based on a visual inspection and for asbestos-containing materials it is augmented with
bulk sampling. Bulk samples for asbestos were taken from representative locations of friable material and
select non-friable or manufactured product suspected of containing asbestos. The selection of the samples
was based on the type of materials present within the specified section of the building. For lead-based paint
surfaces they were treated with a solution of Sodium Sulfide and where a black precipitated would be noted as
lead-containing.

Samples for asbestos are collected by taken a small volume of material (approximately one teaspoon full in
size) from either intact material or preferably from a damaged section. For friable materials where the
remaining material will continue to deteriorate from the section of material where the sample was taken it is
repaired as follows:

    •   For surfacing materials such as fireproofing or acoustical textured material the materials are
        encapsulated with an application of spray paint; and

    •   For thermal insulating materials, they are sealed with an application of lagging adhesive and canvas
        cloth.

The survey of the building for lead in paint consisted of a walk through and physical examination of suspect
surface materials in the select accessible areas within the building. An examination of typical building
surfaces was performed including but not limited to walls, floors, doors, sills/jambs, windows, stair rails etc.
In addition to painted surfaces, coatings such as urethanes, varnishes and lacquers were also examined.

Surface coatings were treated with Sodium Sulfide to indicate the possibility of the presence of lead.

Asbestos was not identified in the designated section of the building investigated for this report in a
concentration equal to or greater then 0.5%. Asbestos may be present in cement drain pipe located under the
finished floors, in the cores of the various fire-rated, metal and wood doors and in gasket or packing in hot
water heating pipe valves and flange joints. Access under the finished floors, in the door cores and in pipe
valves or flange joints was not possible without demolition. Asbestos may be present in other sections of the
building not investigated with this survey.

A summary of the bulk sampling results is provided on Table 4.1 for this 2010 building survey and the
approximate locations where the samples were selected are located on Floor Plan 4.2. Refer to Appendix A-1
for the Laboratory Analytical Certificates and Chain of Custody Forms. As previously stated Asbestos was
not identified in any of the 26 samples collected and analysed in this 2010 survey in a concentration of 0.5 %
or greater.

No samples were taken of apparent fibrous glass or mineral wool applications. These materials can be
positively identified visually by a distinct yellow or pink colour and in itself was never manufactured with
asbestos.

 A - Materials Identified to Contain Asbestos in the Designated Section of the Building Investigated
Asbestos was not identified in any of the building materials found in the designated section of the building
that was investigated.

        Friable Material - The installation of friable asbestos-containing materials were banned after 1986
        under Ontario Regulation 654/85. No friable asbestos-containing materials were found in the
        designated section of the building that was investigated.

        Non-friable Material - Non-friable material can still be purchased in today’s market with the
        exception of any products containing Crocidolite. The handling of these products must follow type 1,
        2 or 3 procedures depending on the method the material is handled. No actual asbestos-containing
        materials were identified in the designated section of the building that was investigated. However,
        several materials are suspected to contain asbestos. Refer to “B – Materials Suspected to Contain
        Asbestos” in the following.



B - Materials Suspected to Contain Asbestos in the Designated Section of the Building Investigated
No additional materials were found in the designated section of the building that was investigated was
suspected to contain asbestos.

•       Cores in Fire-rated Doors - The core material that may be present in select wood and metal doors
        may contain asbestos. Access to the interior of the doors is not possible as breaking or drilling the
        exterior of the door for sampling may void the UL or ULC fire rating. The doors should not disposed
        of if removed until sampling confirms the status of asbestos in the doors.

•       Cement Pipe – Asbestos-containing cement rainwater leader and drain pipe may be present under the
        finished flooring of the building and may also be present associated with drainage pipe between catch
        basins about the site. Existing drain pipe found above grade in the building were copper and cast iron.

•       Gasket and Packing – The gasket and packing in hot water heating pipe fittings and in flange joints
        may contain asbestos. Even if original material was asbestos free replacement material may contain
        asbestos.



C - Materials That Do Not Contain Asbestos in the Designated Section of the Building Investigated
Asbestos was not identified or suspected in the following materials in the designated section of the building
investigated. Any materials found in the designated section of the building found in the room space, above
suspended ceilings and in millwork as described in this section does not contain asbestos.

        Friable Material

C       Thermal Insulation Applied on Pipe and Duct – The fibrous glass or mineral wool type
        applications readily identified by either a distinct yellow or pink color do not contain Asbestos.

        Non-friable Material

•       Acoustical Suspended Ceiling Tile – Two types of acoustical suspended ceiling tiles of the lay
        above type were found in the various rooms of the designated section of the building investigated
        were confirmed by analysis, not to contain asbestos. The ceiling tiles were manufactured by
        Armstrong Industries and was identified by labeling printed on the back of the tile. These tiles had
        respectively a random fissure pattern or an irregular dot pattern on the finished surface of the tile and
        were of the 895 brand or Resistive brand. Four samples of the first tile brand and three of the seconc
        was selected and confirmed by analysis to not contain asbestos. Although the tiles do not contain
        asbestos they may contain silica in a variety of ways as Mineral Wool, Perlite, Diatomaceous Earth or
        as Quartz.

•       Vinyl Composition Floor Tile - All applications of vinyl floor tile found in the designated section of
        the building were confirmed to contain trace levels of Chrysotile asbestsos, however the
        concentration was less then 0.5 %. The tile exhibited a similar mottled pattern with a cream or brown
        coloration and were of the 12" x 12" in size. There were no stock supplies of the tile. Three samples
        of the tile was collected from Classroom 105 and were all analyzed by transmission electron
        microscopy. In addition under Ontario Regulation 278/05 if the owner can confirm by manufacturers
        literature or material safety data sheets that Asbestos is not present, sampling would not be required.

•       Plaster Joint Filling Compounds – There is a limited amount of this material found in the two
        classrooms respectively applied to a common partition wall between classrooms 104 and 105. The
        plaster joint filling compound was applied to gypsum drywall panels. Three samples were collected
        and analysis confirmed that this material does not contain asbestos

•       Caulking – Caulking was applied around door and window frames. The caulking was similar in color
        and texture. Three samples were collected from each of the original building and building addition
        and analysis confirmed that these materials do not contain asbestos.

4.6.2   REGULATION

This report provides a framework for the maintenance of an Asbestos Management Program to ensure
compliance with Ontario Regulation 278/05 the Regulation respecting Asbestos on Construction Projects and
in Buildings and Repair Operations under the Occupational Health and Safety Act for the building. Ontario
Regulation 278/05 applies to maintenance, renovation or demolition work where asbestos-containing material
is or may be disturbed.

The major requirements to building owners under Ontario Regulation 278/05 include:

1.      Provision of a report outlining the locations and content of asbestos in both friable and non-friable
        material in the building to all prospective contractors who are likely to handle or disturb the material.

2.      Advising workers of the building owner who may work in close proximity to both friable and non-
        friable asbestos-containing material and who may disturb the material of its presence.

3.      Periodic inspection of both friable and non-friable material to determine its condition.

4.      Implementation of appropriate control measures, where required, following the precautions and
        procedures prescribed by the Regulation (Type 1, Type 2 or Type 3 operations). The classification of
        the work depends on the type of material, procedures used and the duration of the operation. Refer to
        Table 3.2 Classification of Asbestos Work for further information.

5.      Establishment of a training program for employees of the owner who are likely to handle the material

6.      Annual submission of an asbestos work report form for each employee working in a Type 2 or Type
        3 operation.

7.      Removal of both friable and non-friable asbestos-containing materials, to the extent practicable, prior
        to demolition of a building, or part thereof.

There are more than 3,000 uses of asbestos reported in the literature; most of these are hard or non-friable
materials. Ontario Regulation 278/05 requires that the location of both friable and non-friable materials be
included in the report.

                           before March 16, 1986.




4.6.3    ASSESSMENT

The condition of the friable and non-friable asbestos-containing materials must be assessed on a periodic
basis, which must be performed annually to detect gradual deterioration. In some instances through
examination more frequent assessments may be required.



4.6.3.1 ASSESSMENT OF ASBESTOS-CONTAINING MATERIALS -METHODOLOGY

The assessment of asbestos-containing materials involves the evaluation by the auditor of a number of factors
including but not limited to the following:

C Asbestos type - Asbestos is associated with various lung diseases however higher risks are associated with
  different types of asbestos, Amosite and Crocidolite are considered more hazardous then Chrysotile.



                                NORROX Technical Services Inc.

St Raphael Catholic Elementary School, Mississauga                                            Section 4 - Page 20




C Asbestos content - The potential for elevated levels of airborne asbestos fibre increases with higher
  concentrations from source materials.
C Friability - This is an appraisal of the integrity of the material, its ability to break apart, the higher the
  friability of the material the greater the potential for damage.

C Condition of the material - Fast deterioration and damage indicate sources of dramatic exposure. Slow
  deterioration is associated with a crumbling and grinding of the surface commonly found with dust debris
  nearby on surfaces. The integrity of the material provides a gauge of potential for fall out

C Accessibility to disturbance - This is an evaluation of the ability to impact the material by intentional or
  accidental contact. Materials within easy reach have a much greater potential for exposure.

C Water Damage existing and potential - Water is commonly used to activate a binder that adheres the
  asbestos in material. A good example of this is fireproofing or thermal pipe insulation. When these
  materials become wet the binders soften and allow the material to fall apart releasing the asbestos fibres in
  the air. Material that has become water damaged is recognisable by noticeable staining.

C Activity and vibration - High levels of activity in an area increase the likelihood of disturbing an
  asbestos-containing material. Vibration is also a concern in particular for thermal insulation where the
  motion may be continuous such as a fan in an air handling unit or a loose pipe near a circulating pump
  which can literally shake the material loose.

C Presence in an air plenum or a direct air stream - Air movement over an asbestos-containing material
  that is in poor condition directly entrains the fibre into the air and disperses it over a wide area.

The points above are taken into consideration by the investigator and assessed based on either actual damage
or the potential for damage. Where the materials are found to be in good condition firmly bound and not
likely to fall then no recommendations for further action will be made and the material will be required to be
examined within a year’s time. For material that has an imminent potential for damage, has deteriorated or is
damaged and which is identified by surface crumbling, blistering, delamination and fallen material in powder
or in pieces further action will be recommended. As per Section 5(4)(b) of the O.Reg.838/90, the following
are the four abatement options that may be specified in this report to correct the asbestos concern. These are
as follows:

4.6.3.2 CLEANING

Cleaning of asbestos-containing debris involves the use of either a High Efficiency Particulate Air (HEPA)
Filtered vacuum cleaner or by damp wiping methods. All fallen asbestos-containing material that has become
friable must be promptly cleaned up. Where the material is falling or will continue to fall because of the
extent of deterioration and/or damage, it must be repaired, sealed, permanently enclosed or removed.


4.6.3.3 REPAIRING / SEALING

Repair of thermal insulation usually consists of the application of a lagging (canvas cloth) and mastic (paint
adhesive) or other suitable material to seal areas of damage. This options is usually selected where damage to
a section of thermal insulation is limited and of a minor nature (such that repair activities are not likely to
cause significant disturbance to the underlying friable material and is not likely to recur due to its accessibility
or for other reasons. Sealing exposed or unwrapped surfaces of thermal insulation by the application of a
lagging and mastic may be performed to reduce the potential for future exposure to asbestos fibre. Repair of
sprayed on fireproofing or acoustical textured applications can involve the application of an encapsulant to
limited areas of abraded damage material to seal loose edges and to prevent potential fibre release. However
the under lying material must be capable of supporting the additional weight of the application of an
encapsulant.


4.6.3.4 ENCLOSING

Enclosing asbestos-containing material involves the construction of a physical barrier typically constructed of
drywall or metal sheeting. This option is recommended where the removal of deteriorated thermal insulation
or fireproofing isn't practicable of where damage is likely to recur without a protective barrier. If the
installation of a barrier is likely to disturb the asbestos-containing material the work must be performed within
an enclosure usually constructed of polyethylene sheeting.


4.6.3.5 REMOVING

Removal of thermal insulation of sprayed on material is recommended as a corrective action in areas where
the asbestos-containing material is damaged beyond repair or where the material is likely to be disturbed
during activities such as renovation or maintenance work. The methods employed in the removal work are
primarily dependent on the amount of material to be removed and the type of asbestos as defined in the
regulation. For limited quantities of thermal pipe insulation Type 2 procedures may be followed which
usually involve performing the work within a glove containment bag or for surfacing materials within a minor
enclosure lined with polyethylene sheeting. Where more than a minor amount of asbestos-containing
materials are to be removed in a given area, more stringent Type 3 procedures are used. Additional
precautionary measures such as the establishment of a negative air pressure differential inside the work area
relative to the exterior and the monitoring of exposure is often used.

4.6.3.6 ASSESSMENT RESULTS & RECOMMENDATIONS FOR CORRECTIVE ACTION

No asbestos-containing materials were confirmed in the designated section of the building that was
investigated. Demolition would be required to access items in the building that are assumed to contain
asbestos.

      •   No further action is recommended in these locations for the continued use of the building.

      •   Prior to demolition or renovation any cement drain or rain water leader pipe found under the finished
          floor of the building, any cores in metal or wood doors and gasket or packing found in hot water
          heating pipe valves or on flange joints should be sampled and analyzed to confirm the status in these
          materials prior to performing any work.

      •   It is recommended that a building audit for asbestos in accordance with the requirements of Ontario
          Regulation 278/05 be performed for all other areas of the school building.

4.6.3.7 RESTRICTIONS

Potential exposure to asbestos fibre may result if precautions listed below are not followed. Personnel subject
to exposure are included with the discussion per each section.

1.        This report is to be made available by the Asbestos Co-ordinator for the building and read by all
          persons, including outside work forces (service personnel and contractors), who may work in close
          proximity to the materials and who may disturb these materials.

2.        All work performed on materials containing asbestos and all work, which may disturb materials
          containing asbestos, must be performed in accordance to the Regulation, and when the particular
          section of the building is cleared of occupants.

3.        Only personnel trained according to an Asbestos Training Program are permitted to work on
          Asbestos-containing Materials. A record of exposure those individuals working on a Type 2 or 3
          Operation must be submitted to the Ontario Ministry of Labour annually or when the employee
          terminates service.

4.        Restrict access where asbestos-containing materials are actively being disturbed or handled.



4.7       BENZENE

No tanks or process operations were observed or appear to have been present in the designated section of the
building that was investigated. Therefore it is not expected that benzene will be present.

4.8       COKE OVEN EMISSIONS

There are no or likely to have been in the building any furnaces, smelting operations or coal stockpiles on the
site. As such coke emissions are not a concern.



4.9       ETHYLENE OXIDE

No tanks or process operations were observed or may have been present in the designated section of the
building that was investigated. Therefore it is not expected that ethylene oxide will be present.



4.10      ISOCYANATES

No tanks or process operations were observed or may have been present in the designated section of the
building that was investigated. Therefore it is not expected that isocyanates will be present.



4.11      LEAD

4.11.1 RESULTS

In general the concentration of lead in paint films was slight in the designated section of the building that was
investigated as the treatment of Sodium Sulphide produced a slight black precipitate on the painted surfaces.
It should be concluded that lead may present in the painted surfaces but in very low concentrations.
Applications such as paint on structural steel were not tested, as it would be expected for the paint to contain
in the order of 80% lead in the solids. Exterior surfaces were also not tested as these were out of the specified
area of the building requiring investigation but expected to have a higher concentration of lead.

The regulations in Ontario are not limited to lead in paint alone. As such it is prudent to assume that lead is
present in the following observed building materials;

      •   As a component of the solder on sweated on joints between copper pipe and fittings including
          domestic water supply pipe;
      •   As a component of the solder on wire connections of electronic components;
      •   As a component in the lead acid storage batteries found in the emergency lighting; and
      •   As a component of the fuse link in the fire dampers.

4.11.2 REGULATORY REQUIREMENTS

Section 10 of the Designated Substance Regulation applies with respect to lead, to every employer and
worker at a workplace where lead is present, produced, processed, used handled or stored and at which a
worker is likely to be exposed to mercury O. Reg. 490/09, s. 10. This obligates employers who have lead in
their workplace perform an assessment in writing of the exposure or likelihood of exposure of workers in the
workplace to the inhalation ingestion and contact with lead.



4.11.3 ASSESSMENT OF PAINT FILMS - METHODOLOGY

The assessment of lead based paint materials involves the evaluation by the auditor of the general condition of
the paint films. Various factors come into play with the evaluation including but not limited to the following:
    • Peeling paint from walls with deposits on surfaces;
    • Cracked substrates;
    • Chalking or flaking; and
    • Water Blistering including rotted wood substrate.



CORRECTIVE ACTION OPTIONS - RATIONAL

The points above are taken into consideration by the investigator and assessed based on either actual damage
or the potential for damage. Where the materials are found to be in good condition firmly bound and not
likely to fall then no recommendations for further action will be made and the material will be required to be
examined within a year’s time. For material that has an imminent potential for damage, has deteriorated or is
damaged and which is identified by surface crumbling, blistering, delamination and fallen material in powder
or in pieces further action will be recommended.

The following are the four abatement options that may be specified in this report to correct the asbestos
concern as follows:



4.11.3.1 CLEANING

Cleaning of lead based paint debris involves the use of either a High Efficiency Particulate Air (HEPA)
Filtered vacuum cleaner or by damp wiping methods. All fallen lead based paint film that has been reduced
and fallen should be promptly cleaned up. Where the material will continue to deteriorate and fall should be
sealed, permanently enclosed or removed.

4.11.3.2 SEALING

Sealing of damage paint surfaces involves the reapplication of new paint over the old film. This option is
acceptable where the underlying paint is sound and further deterioration is not likely such as water
penetration, humidity or the base substrate is not chalking. The lead in the paint may still leech through the
new finish. As such this option is only a temporary solution.



4.11.3.3 ENCLOSING

Enclosure typically involves the application of narrow diameter gypsum or panelling to isolate the old wall
finish. This solution is permanent until demolition. The advantage of this method also has the tendency to
provide a new finish to wall surfaces that may be cracked or uneven.



4.11.3.4 REMOVING

Removal of the paint finish is recommended as a corrective action in areas where the paint is deteriorating,
where other problems are likely such as moisture, high humidity, accidental contact or vandalism. When
removal is contemplated, two options are available scarifying the surfaces or removal by chemical strippers.
Work area isolation within an enclosure lined with polyethylene sheeting and the establishment of a negative
air pressure differential inside the work area relative to the exterior, filtering of the work area air through High
Efficiency Particulate Air (HEPA) filters are recommended.


4.11.4 ASSESSMENT OF EXPOSURE

4.11.4.1 Assessment of Lead in Lead-based Paints

All painted films were found to be intact with only minor chipping observed. No recommendations for further
action are required.

The presence of lead in building finishes left intact or found peeling in a few locations as is this case is not
expected to produce substantial exposure for workers to lead through contact, inhalation or ingestion. Actual
exposure although expected to be low is not within the scope of this assessment and can only be appraised by
air monitoring.

Any operation involving lead-based paints may potentially produce significant exposures to lead if adequate
controls are not provided. Exposure varies with the type of operation being employed.

    •   The presence of lead in building finishes left intact or found peeling in a few locations produces little
        exposure for workers to lead through contact, inhalation or ingestion.

    •   Operations involving the hand sanding and scrapping of lead based paints can elevate exposure
        through inhalation. The use of a negative pressure respirator equipped with high efficiency particulate
        air (HEPA) filters is recommended to reduce exposure.

    •   Operations involving the machine sanding or abrasive cutting of paint and other surface coatings
        containing lead can elevate levels of much finer dust. The spray application of a lead bearing paint or
        coating produces a respirable fume. These operations increase the likelihood of exposure by
        inhalation. A negative pressure air-purifying respirator equipped with HEPA filters is recommended
        for these operations.

    •   Operations involving oxyacetylene torches or other heating operations produce the most significant
        exposure to lead in particular through inhalation and by contact of lead fumes solidifying on skin. A
        powered air-purifying respirator equipped with HEPA filters and full body covering is recommended
        for these operations.



4.11.4.2 Lead Solder

         Water Pipe and Electronic Equipment
Lead found in solder of pipe systems including water supply and lead found in solder in electronic
components poses no threat to the work force from occupancy by inhalation, ingestion or by contact with the
exception of maintenance activities that would result in heating the lead solders. The maintenance of the pipe
or electrical component may produce some exposure to lead fume during the sweating on of lead solders but
for a short duration of time. Inhalation is the source of entry and exposure is not very significant for short
duration work.



4.11.4.3 Waste Disposal

All items identified in this section may be disposed of as regular non-hazardous waste unless concentrated.
Metallic lead may be reclaimed through scrap metal dealers

Disposal of waste paint is covered by the Ministry of Environment, under O. Reg. 347 made under the
Environmental Protection Act. To determine if a waste containing lead poses a disposal problem it must
undergo the "Leachate Extraction Procedure" as defined in the regulation. This test would measure the
susceptibility of lead to leach out of the waste and therefore the potential to contaminate ground water. A
waste producing a leachate containing in excess of 5 mg/L of lead would be considered a Toxic Hazardous
Waste and a leachate containing a level of between 0.5 and 5 mg/L of lead would be considered a

Registerable Waste. A small quantity exemption of 25 kg of waste per month applies where the owner is not
required to register as a waste generator.



4.11.5 RESTRICTIONS

Potential exposure to lead and lead-based paints may result if precautions listed below are not followed.
Personnel subject to exposure are included with the discussion per each section.

1.       This report is to be made available by the Lead Co-ordinator for the building and read by all
         persons, including outside work forces (service personnel and contractors) and those who may disturb
         these materials as lead is a designated substance under the Occupational Health and Safety Act

2.       All work performed on materials containing lead are recommended to comply at this time with the
         procedures specified in the Ontario Ministry of Labour's Guideline for Lead on Construction Projects
         and when the particular section of the building is cleared of occupants.

3.       Only personnel trained according to a Lead Training Program should be permitted to work on
         Lead-containing materials.



4.12   MERCURY
4.12.1 RESULTS

No samples were taken for mercury however based on the age of the building and the common use of
Mercury at this time it is presumed to be present in the following materials:

     •   As a gas in the observed florescent light tubes found in service throughout the area of the building
         investigated; and

     •   As a bactericide or stabiliser in paints or caulking.



4.12.2 REGULATORY REQUIREMENTS

Section 11 of the Designated Substance Regulation applies with respect to mercury subject to subsection (2)
to every employer and work worker at a workplace where mercury is present, produced, processed, used
handled or stored and at which a worker is likely to be exposed to mercury O. Reg. 490/09, s. 11 (1). This
obligates employers who have mercury in their workplace perform an assessment in writing of the exposure
or likelihood of exposure of workers in the workplace to the inhalation ingestion and contact with mercury.

4.12.3 ASSESSMENT
   A - Florescent Light Tubes

Florescent light tubes contain small quantities of mercury gas. These sealed units do not pose any harm in the
workplace except in the case of breakage. There are no liquid or residue present after breakage and spill
cleaning is not a concern. A recommended practice is to evacuate the work area when breakage occurs. The
gas will diffuse in about five to ten minutes and cleanup of the tubes can be performed. Mercury can be taken
into the body by inhalation only from this source.

     B - Mercury in paints

The same precautions as those indicated for lead-based paints would apply to mercury in paints.



4.12.4 WASTE DISPOSAL

Mercury found in light tubes can be recycled and mercury in painted surfaces that have not been concentrated
can be disposed of as regular waste.

Disposal of waste paint is covered by the Ministry of Environment, under O. Reg. 347 made under the
Environmental Protection Act. To determine if a waste containing mercury poses a disposal problem it must
undergo the "Leachate Extraction Procedure" as defined in the regulation. This test would measure the
susceptibility of mercury to leach out of the waste and therefore the potential to contaminate ground water.



4.12.5 RESTRICTIONS

Potential exposure to mercury and mercury-based paints may result if precautions listed below are not
followed. Personnel subject to exposure are included with the discussion per each section.

1.       This report is to be made available by the Mercury Co-ordinator for the building and read by all
         persons, including outside work forces (service personnel and contractors) and those who may disturb
         these materials as mercury is a designated substance under the Occupational Health and Safety Act

2.       Only personnel trained according to a Mercury Training Program should be permitted to work
         on elemental Mercury and Mercury-containing materials.

4.13    SILICA

4.13.1 RESULTS

No samples were taken specifically for silica, however mineral wool, fibrous glass, ceramic fibre and quartz
are found in various building materials and are all forms of silica. Additionally it is presumed to be present in
cement, cement blocks, bricks and mortar of the building. All these forms are not in a respirable size and are
not readily released in the building's air.



4.13.2 REGULATORY REQUIREMENTS

Section 12 of the Designated Substance Regulation applies with respect to silica to every employer and work
worker at a workplace where silica is present, produce, processed, used handled or stored and at which a
worker is likely to be exposed to silica O. Reg. 490/09, s. 13. This obligates employers who have silica in
their workplace perform an assessment in writing of the exposure or likelihood of exposure of workers in the
workplace to the inhalation of silica.



4.13.3 ASSESSMENT

Unless the silica in the specified materials is reduced to respirable size (5 um or less) and the airborne
concentration exceeds the time weighted average exposure of 0.2 milligrams per cubic metre in air, no
adverse health effects are expected to occur. Building construction, renovation and demolition do not
normally raise excessive exposure to silica where the application of water is used to suppress the generated
dust. There is little likelihood for the work force to be exposed to excessive levels of respirable silica dust if
the material is suppressed with water spray.



4.13.4 RESTRICTIONS

Potential exposure to Silica may result if precautions listed below are not followed. Personnel subject to
exposure are included with the discussion per each section.

1.      This report is to be made available by the Silica Co-ordinator for the building and read by all
        persons, including outside work forces (service personnel and contractors) and those who may disturb
        these materials as silica is a designated substance under the Occupational Health and Safety Act

2.      All work performed on materials containing silica are recommended to comply at this time with the
        procedures specified in the Ontario Ministry of Labour's Guideline for Silica on Construction
        Projects and when the particular section of the building is cleared of occupants.

        Materials that may contain Silica.



4.14    VINYL CHLORIDE

No tanks or process operations were observed or appear to have been present in the specified sections of the
building that was investigated. Therefore it is not expected that vinyl chloride will be present.

5.0     RECOMMENDATIONS

The two areas of the building investigated will undergo renovations and the following recommendations are
provided for the continued use of the structure and for renovation. Following these recommendations
applying to the designated areas of the building that were investigated will ensure that an effective control
program in dealing with designated substances is maintained:



5.1     FOR CONTINUED USE OF EXISTING BUILDING

The following precautions apply to the building as it stands:

        Asbestos:

C       Comply with the requirements of the Asbestos Management Control Program for the Dufferin-Peel
        Catholic District School Board (Latest Edition)

C       A copy of this report must be kept and maintained on the premises to clearly identify the locations of
        the suspect asbestos-containing materials (Cement pipe possibly found under the finished floors,
        cores in doors and gasket & packing in hot water heating pipe valves and flange joints in the select
        locations of the building. The report must be altered to reflect removals performed in order of
        ensuring that the status of the select locations of the building are kept current.

C       The handling of suspect non-friable asbestos-containing cement drain or rainwater leader pipe, cores
        in doors and gasket or packing, should comply with the requirements of a Type 1. Type 2 or Type 3
        operation depending on the following
        C       Quantity of material that will be removed;
        C       Whether hand tools or power tools (if equipped with a dust collection device and equipped
                with HEPA filters); or
        C       Whether the material will be wetted.

C       A record should also be maintained of any abatement work performed in the building. The records
        should detail who performed the work, methods employed and records including a notice of project
        for Type 3 operations for non-friable material where cut, shaped or abraded with a power tool not
        equipped with a dust collection device and fitted with a HEPA filter. Waste disposal records should
        also be maintained.

C       Should any asbestos-containing materials be removed from the building this material may be stored
        on site in a secure location. After three months the Ministry of Environment and Energy should be
        contacted for extension of storage time if required.

        Lead:

C       Although lead is likely present in the building in various materials including paint, the likelihood of
        exposure is low if these materials are not physically disturbed. Given this situation, a management
        program should be established, concerning lead and lead-containing materials.

C       Painted surfaces are the most probable sources for lead exposure and should be hand sanded or
        scrapped and patched in preparation for new paint. Fallen and peeling paint surfaces should be
        collected with a high efficiency particulate air (HEPA) filtered vacuum.

C       Where power tools or torches are used to remove painted surfaces or to cut through painted surfaces,
        the work force should be required to wear a high efficiency particulate air filtered respirator (negative
        pressure for power tool use & powered positive pressure for hot work) and dust tight protective
        clothing. For extensive renovations the work area should be isolated from other parts of the building
        and a negative pressure differential should be established with respect to the rest of the building. The
        air with in the work area should be collected through a filter fan unit equipped with HEPA filters and
        discharged outside of the building. All surfaces contaminated with lead dust should be cleaned with
        HEPA filtered vacuum cleaners or by damp wiping.

C       If lead or lead-containing materials have been concentrated on the property in excess of 25 kg per
        month registration with the Ministry of Environment and Energy is required and before any disposal
        of the concentrated materials a leachate toxicity test will be required.


        Mercury:

C       Mercury is also likely to be present in the building and the same recommendations as presented for
        lead in paint will also apply to mercury in paint.

C       Indoor breakage of fluorescent light tubes should be avoided, where this occurs the area should be
        evacuated for a short period of time to permit the mercury gas to dissipate.


        Silica:

C       Silica is likely present bound within concrete, mortar and other materials in the building structure.
        Unless these materials are released and fractured through sandblasting and or other abrasive action to
        resperable size no further action is recommended.

5.2     FOR EXTENSIVE RENOVATION OR PARTIAL DEMOLITION OF BUILDING

Except for asbestos all the other Designated Substance Regulations apply to industrial establishments and not
to construction. Because of the lack of regulatory control it is imperative that a contractor retained for
demolition has a proven record in managing designated substance and operates under a control program so
that a problem does not occur by mismanagement. As various specific areas of the building is slated for
renovation or demolition special precautions are required for the removal of specific designated substances as
follows:

        Asbestos:

C       The removal of Asbestos-containing materials, including friable material and non-friable materials
        must precede all demolition work and must be removed to the extent practicable.



        Other Designated Substances:

C       The other designated substances can be removed as part of the demolition process including:

        C        Lead in solders of electrical components and lead as solders in pipes can be recycled and is
                 not a restricted substance when disposed of through metal recycling;

        C        Lead and mercury in paint should be handled as follows:
                 C      For fallen and peeling paint surfaces the debris should be collected with a high
                        efficiency particulate air (HEPA) filtered vacuum. ; and

                 C        For intact painted surfaces the materials likely can be disposed of intact without any
                          further action.

                 The Ontario Ministry of Labour's Guideline for Lead on Construction Projects should be
                 followed

        •        Mercury in fluorescent light tubes should be recycled.

        •        Silica in building materials. (Normal building renovation or demolition activities are not a
                 concern and dust suppression is easily accomplished by water spray. Concrete, cement block
                 and brick should not be cut dry with power tools. Respiratory protection is dependent, on the
                 type and airborne concentration of resperable silica present in the particular work
                 environment.)

                 should be followed.

Prior to the disposal of building materials a leachate toxicity test in compliance with R.R.O. 1990 / Regulation
347 as revised by Ontario Regulation 558/00 may be required by the local waste receiving site or the Ontario
Ministry of Environment. Prior to disposal, these authorities should be consulted with and tests performed
where required.

Bulk samples were analyzed using Polarized Light M icroscopy with Dispersion Staining Techniques. This analysis is performed in accordance with the procedures specified in the
“US Environmental Protection Agency. Test Method EPA/600/R-93/116: Method for the Determination of Asbestos in Bulk Building M aterials. June 1993", specified in Ontario
Regulation 278/05 made under the Occupational Health and Safety Act, “Designated Substances - Asbestos on Construction Projects and in Buildings and Repair Operations. Asbestos
fibre and other material components are identified by a combination of morphology, pleo-chroism and colors present, refractive indices, birefringence, extinction angle, sign of
elongation, and colors under specific refractive fluids. The % composition of asbestos and non-asbestos fibres reported are measured by subjective visual means based on specialized
training, experience and comparison to standard area projections. The limit of detection for routine analysis is 0.5%.

All results pertain only to the material tested.
