 What in the back of your half ton
• Exposure to chemicals poses serious problems
  for many workers. Chemical exposure may
  cause or contribute to many serious health
  effects such as heart ailments, kidney and lung
  damage, sterility, cancer, burns, and rashes.
  Some chemicals may also be safety hazards
  and have the potential to cause fires,
  explosions, and other serious accidents

   – Hazardous Material Identification Guide (System)
• NFPA
   – National Fire Protection Agency
• DOT
   – Department of Transporation




               P bar Y Safety Consultants Alberta Canada
   NFPA vs. HMIS

• Both systems have three color-coded fields to indicate the
  flammability (red), health (blue), and reactivity (yellow) hazards
  associated with the material.
• Both use a system of five numbers, ranging from 0 to 4, to indicate
  the severity of hazard, with 0 being the least and 4 being the most
  hazardous.




                       P bar Y Safety Consultants Alberta Canada
    NFPA vs. HMIS

• Differ in the fourth, white field
   – special handling in the NFPA system
   – protective equipment in the HMIG system).
• HMIS is intended as an HCS compliance tool
   – employees who must handle hazardous chemicals in the workplace
      are the intended audience
• NFPA was designed for first responders.
   – numbers assigned in the NFPA system assume that a fire, spill, or
      emergency is present

  enforced by government, developed by ACGIH. (American
  Conference of Governmental Industrial Hygienists)

• RELs - Recommended Exposure Limits, established by NIOSH,
  for review by OSHA for revising PELs.  (Natl. Institute of
  Occupational Safety & Health)

• STEL – Short Tern Exposure Limit, time weighted average
  concentration to which worker can be continuously exposed
  for a short period (typically 15 minutes).

                        P bar Y Safety Consultants Alberta Canada
       Hazard Specific Regulations:
       Airborne Contaminants cont.
• C – Ceiling Limit, not a time weighted average, but
  instead a maximum concentration that should not be
  exceed at any time.
• IDLH – Immediately Dangerous to Life or Health,
  defined as a concentration or condition that poses an
  immediate threat to life or health.
• Difference between PEL & TLV – with various
  designations: OSHA – PEL, PEL-TWA, PEL-C, PEL-
  STEL, ACGIH – TLV-TWA, TLV-STEL, & TLV-C.

                  P bar Y Safety Consultants Alberta Canada
 Other Hazard Specific Regulations
• Relating to risks associated with energy, noise, heat,
  cold, radiation, vibration, repetitive motion, dust,
  and oxygen deficient environments
• Example: Ergonomic regulations to alleviate the the
  development of Carpal Tunnel Syndrome
• Example: OSHA Standard for oxygen deficient
  atmosphere is <19.5% oxygen, ACGIH defines it at
  18%
   – At what concentration do we see physiological effects of
     oxygen deficiency ?

                     P bar Y Safety Consultants Alberta Canada
        HazCom: Workplace Hazard
        Communication Standards

  elements of hazard communication programs
• The Laboratory Safety Standard is a hazard
  communication program for laboratories only
• HazWoper covers hazardous waste clean-up workers
  TSD facilities, and emergency responders to chemical
  spills
   – 40-hr H&S training offered as part of OCC’s degree
     program falls under the HazWoper Standard.

  individuals who are likely to witness or
  discover a hazardous substance release and
  who have been trained to initiate an
  emergency response sequence by notifying
  the proper authorities of the release
• They would take no further action beyond
  notifying the authorities of the release

             P bar Y Safety Consultants Alberta Canada
       First Responder Operations
                  Level
• Trained to respond in a
  defensive fashion without
  actually trying to stop the
  release
• Function is to contain the
  release from a safe
  distance, keep it from
  spreading and to prevent
  exposures

             Purpose of OSHA’s
      Hazard Communication Standard

 OSHA’s Hazard Communication Standard (HCS) is
  designed to ensure that information about hazards
  chemicals disseminated.
 Chemical manufacturers are required to evaluate
  the hazards of the chemicals they produce, and to
  provide information about them through labels and
  material safety data sheets (MSDS’s).
 Employers who use hazardous chemicals in their
  workplaces must follow this Standard to assure
  employee safety.

  recommended by the chemical manufacturer,
  importer or employer are required”




              P bar Y Safety Consultants Alberta Canada
              Carcinogenicity
• If a chemical is listed as carcinogen by IARC or
  NTP, it must be noted on the SDS

• If OSHA finds a chemical to be a carcinogen, it
  must be noted on the SDS




                 P bar Y Safety Consultants Alberta Canada
           GHS Hazard Classification

– Acute Toxicity (any route of exposure)
– Skin Corrosion or Irritation
– Serious Eye Damage or Eye Irritation

                 P bar Y Safety Consultants Alberta Canada
             GHS Hazard Classification

• The list of chemicals presenting a ‘Physical’ hazard
  was deleted from the current HCS and the proposed
  HCS has identified a new listing

• A ‘Physical Hazard’ means a chemical that is
  classified as posing one of the following hazardous
  effects:




                   P bar Y Safety Consultants Alberta Canada
             GHS Hazard Classification

–   Explosive
–   Flammable (gases, aerosols, liquids, or solids)

                   P bar Y Safety Consultants Alberta Canada
              GHS Hazard Classification

• The HCS does not address environmental hazards
  and OSHA does not have jurisdiction over that. There
  are environmental hazard classifications:
   – Hazardous to the Aquatic Environment
      • Acute Aquatic Toxicity
      • Chronic Aquatic Toxicity
         – Bioaccumulation Potential
         – Rapid Degradability




                     P bar Y Safety Consultants Alberta Canada
          Hazardous Chemical
• OSHA classified as Hazardous Chemicals:
  – Pyrophoric gases, signal word “danger”, “catches
    fire spontaneously if exposed to air”*
  – Simple asphyxiants, signal word “warning”, “may
    displace oxygen and cause rapid suffocation”*
  – Combustible dust, signal word “warning”, “May
    form combustible dust concentrations in the air”*
  *Hazard Statements

o Uniform format by June 1, 2015 with 11
  required sections:
 Section 1, Identification                      Section 7, Handling and storage
 Section 2, Hazard(s)                           Section 8, Exposure
 Section 3, Composition/information                controls/personal protection
    on ingredients                              Section 9, Physical and chemical
 Section 4, First-aid measures                     properties.
 Section 5, Fire-fighting measures              Section 10, Stability and reactivity
 Section 6, Accidental release                  Section 11, Toxicological
    measures                                       information




                       P bar Y Safety Consultants Alberta Canada
The New Safety Data Sheets (cont.)
o Other sections on the new SDS:
   • Section 12, Ecological information*
   • Section 13, Disposal considerations*
   • Section 14, Transport information*
   • Section 15, Regulatory information*
   • Section 16, Other information, includes the date of
       preparation or last revision.
o Only 1 set of data sheets is required. May be a time where
  MSDSs/SDSs under both standards will be present in the
  workplace. This situation is acceptable to OSHA, and employers
  will not be required to maintain two sets of MSDSs/SDSs.
*Since other agencies regulate this information, OSHA will not enforce
   Sections 12 through 15; however, the SDS must include at least the
   heading names for those sections.

                       P bar Y Safety Consultants Alberta Canada
  Hazard Communication Standard
             Label
• Labels will be required to have
  pictograms (to convey hazards about
  the chemical), a signal word, hazard
  and precautionary statements, the
  product identifier, and supplier
  identification.
• NFPA and HMIS labels are permitted;
  however, the information provided
  must be consistent with the new HCS.
