Why must you
take this training?
It’s the law.
Right to Know Hazardous Waste
Laboratory Safety Std. Clean Air
There are University policies and
procedures that you need to understand.
There are also extremists who vandalize workplaces where they
suspect animal research is being conducted and others who try to
gain access where toxins or other hazardous materials are used.
Protect your lab and your research:
• NEVER prop open any card or key
access corridor doors.
•Don’t let people ‘piggy-back’ to gain
access to restricted areas.
• Keep your lab doors closed and locked
•Question strangers, and report suspicious
activity to campus security.
There are two general hazard classes that
must be evaluated when assessing the
safety of a chemical:
The nature of the chemical itself… how it behaves
How an exposure might affect you
Compressed Gas - cylinders of compressed gas are under
Corrosivity – strong acids and bases can cause visible
destruction of metal at the site of contact.
Flammability - both solid and liquid chemicals can serve as
fuel sources to support a fire. Flammability is based on flash
points. The flash point of a liquid is the minimum temperature
that a liquid gives off enough vapor to ignite if an ignition
source such as heat, flame or spark is present.
Oxidizability – ability to give off oxygen as the compound
decomposes which will help sustain combustion
Reactivity - many substances will react violently if allowed
contact with air, water or other chemicals. Friction, shock,
light or heat can be enough to trigger some reactions.
Gas Cylinder Safety
Storage and Handling
Gas cylinders should not be stored in exits
or egress routes or blocking any safety
equipment such as eyewashes, safety
showers or fire extinguishers.
Gas cylinders (excluding lecture bottles)
should be stored in an upright position and
with safety caps in place unless in use.
Use only the appropriate regulator for the
Gas cylinders must be secured with a
chain or appropriate belt above the
midpoint but below the shoulder of the
cylinder. See picture.
Irritants - cause reversible inflammation of skin, eyes or nasal passages.
Sensitizers - cause allergic reaction after repeated exposures. Individual
sensitivities vary. Can cause watering or itching eyes, reddening of the skin, hives
even an asthmatic attack.
Carcinogens - alter DNA or cause cells with altered DNA to multiply or cancer
Systemic or Target Organ Toxins - typically target a specific organ or system
(liver, kidney, blood, nervous system, reproductive system, etc.).
Corrosives –acid, bases and some organics that can burn the skin, eyes, mucous
membranes and respiratory tract. HF not your typical mineral acid. It attacks the
Toxins – anything that can be poisonous to your body, toxicity is based on
No Exposure, No Problem
Working with or around hazardous chemicals does not
necessarily mean that a person’s health will be affected.
The link between hazardous chemicals and adverse health
effects lies in exposure.
Routes of Entry
Road map to the body
Breathing it in
Ingestion- Getting it on skin
Getting it in mouth
puncture, needle stick or a chemical getting into
an open cut
a rapid, sudden exposure
the harmful effects are immediate
repeated, small exposures
the harmful effects are delayed
sometimes as long as 40 years
the time between the exposure and the effect
Personal Protective Equipment (PPE)
Gloves - No single glove material is appropriate for all chemicals
- Choose glove with lowest permeability to the chemical you are using
- Consult CHP as a guide
Clothing – minimize areas of exposed skin
Eye Protection – If chemicals or infectious agents could be splashed
into your face, protect your eyes with glasses, goggles or a face shield.
REQUIREMENTS AT NOTRE DAME
Gloves are required anytime you are handling chemicals,
biological agents,and/or radioactives.
Eye protection is required anytime you are working with
chemicals, biological agents outside a Biosafety cabinet, Radioactive
materials or involved with sanding or grinding operations
Goggles should be worn when working with corrosives or if a splash
hazard is present.
Lab coat is required if you are working with biological or radioactive
Material Safety Data Sheet
You have a right to information about every chemical in
your workplace, and the format created to convey this
information is the Material Safety Data Sheet (MSDS).
Included in every shipment of hazardous chemicals
Required to be in every work location where chemicals exist
Created by chemical manufacturers
NOT all created equal
- Identity of material (chemical name, synonyms)
- Physical and chemical properties
- Health hazards and “safe” exposure levels
- Symptoms of exposure
- Applicable routes of entry to the body
- Carcinogen listing
- Name, address, and emergency phone number of
- Precautions for safe handling
- Control measures, PPE
Finding an MSDS
Chemical manufacturers and distributors
CANNOT refuse a request for an MSDS.
There are excellent on-line MSDS
University of Notre Dame
Chemical Hygiene Plan (CHP)
Roles and Responsibilities
Contains information and procedures that laboratory
personnel can use to protect themselves from the chemicals
they work with
First place to look for answers to questions you might have
regarding chemical or laboratory issues
- Glove selection - Emergency Response
- Chemical compatibility -Waste Management
- Standard Operating Procedures (SOPs)
- Pre-approval notifications
Maintain all electrical equipment in proper and good working
Routinely examine all wiring, plugs power strips and
extension cords for signs of exposed wire or deteriorating
No tripping or hanging hazards
Chemical Fume Hood
Airflow into the hood prevents
chemicals inside from migrating
out into your breathing zone.
If air velocity into the hood is
impeded or slowed, the hoods
ability to capture chemicals is
Factors that affect airflow:
•Bulky objects inside
Fires/accidents 911 or 574-631-5555 from cell phone
(Risk Management and Safety)
After Hours Spills 911 or 631-5555 from cell phone
State the type of emergency and the exact location of
emergency – Building and Room number
If a chemical is involved spell the chemical name to the
If you are leaving the area, give a phone number where
responders can contact you.
Needle Sticks: Ocular Exposures: Dermal Exposures:
•Wash thoroughly •Rinse at eyewash at •Rinse under water at
with soap and water least 15 minutes least 15 minutes
•If large area of body
•Identify source of •Hold eye open to is involved, use

wash drench yourself.
•Seek Medical Treatment contaminated clothing
•If you are an employee, your supervisor must fill out an
Safety Shower and Eyewash
•Do I know where they are located?
•Do I know how they work?
•Do I know that they work?
•Are they accessible?
Identify the chemical
Assess your ability to safely
contain and clean up the spill:
(spill size, chemical toxicity)
I CAN safely I CANNOT safely
clean it up clean it up
Notify coworkers and Notify coworkers and
secure the area vacate/secure the area
Use spill kit to contain and clean
up the spill (MSDS helps) Call Risk Management
Lab Workers are responsible to clean up spill if:
- It is a chemical that they work with
- They have the proper personal protective equipment available
- Lab size quantities
How to Use a Fire Extinguisher

Intuitively we should all understand that potentially harmful chemicals cannot be disposed
of with the regular trash…
USEPA has set strict regulations governing
the disposal of hazardous chemicals.
$27,500 per violation, per day!
Orange Biohazard Bags
Orange Biohazard Bags
contaminated waste that
has been decontaminated
(autoclaved) by lab
personnel. May be
disposed of in regular
trash if brown bagged.
Biohazard bags cannot be
used for disposal of

Risk Management and
All other waste…
Gloves, paper, etc if not contaminated:
disposed of in regular (clear) trash bags and
bags are to be removed by custodians daily.
Broken Glass: if clean, should be disposed of in
a puncture proof box marked “Broken Glass”.
Empty bottles must be triple rinsed, label
defaced and cap removed for building services
to remove them.
Shipments of chemicals, biological agents/samples, and
radioisotopes pose a hazard to everyone involved in the
transportation process. For this reason there are very strict
regulations regarding packaging, labeling and documenting
such shipments. AT LEAST 48 business hours notification
PRIOR to desired ship date IS REQUIRED
Chemical Always contact Lisa Phillips in RM&S prior to
Shipments attempting to ship a chemical.
Biological Always contact Lisa Phillips in RM&S prior to
Shipments shipping biological/infectious materials.
Radioactive Always Andy Welding in RM&S prior to attempting
Shipments to ship a radioactive material.
