Will affect nearly 40 million workers and 5 million
workplaces

•
It is estimated that
implementing the GHS will
prevent 43 fatalities and 585
injuries and illnesses annually

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

In OSHA’s rule there is a hazard category called
“Hazards not otherwise classified” which is not in
the UN GHS system
–
… a substance that has an identified hazard,
but does not meet classification criteria for
physical or health hazard under GHS
–
These substances are covered by the current
hazard communication law---so OSHA did not
want GHS to result in a less protective law
–
OSHA added pyrophorics, combustible dust,
and asphyxiant s to the definition of “hazardous
chemical”

This content discusses the changes introduced by the Global Harmonized System in Hazard Communication Standards (HCS). It highlights the impact on classifications, labels, safety data sheets, and information and training requirements. The GHS aims to enhance workplace safety by providing a standardized framework for hazard communication, affecting millions of workers and workplaces globally. The Hazard Classification criteria for both health and physical hazards are outlined, emphasizing the importance of these classifications in promoting a safe work environment.

Hazard Communication and the Global Harmonized System Joann Natarajan OSHA Austin Area Office
What Has Changed? Issued March 26, 2012 Affects 29 CFR 1910.1200 Affects other regulations: Welding Flammables, and substance specific standards Label and hazard warnings were harmonized in the substance specific regulations 2
GHS The major changes to the HCS: Hazard Classification Labels Safety Data Sheets Information and Training Will affect nearly 40 million workers and 5 million workplaces
GHS It is estimated that implementing the GHS will prevent 43 fatalities and 585 injuries and illnesses annually The DOT has already modified their requirements for classification and labeling to be consistent with UN transport requirements and the GHS
GHS Hazard Classification The list of chemicals presenting a Health hazard was deleted from the current HCS and the proposed HCS has identified a new listing A Health Hazard means a chemical which is classified as posing one of the following hazardous effects:
GHS Hazard Classification Acute Toxicity (any route of exposure) Skin Corrosion or Irritation Serious Eye Damage or Eye Irritation Respiratory or Skin Sensitization Germ Cell Mutagenicity Carcinogenicity Reproductive Toxicity Specific Target Organ Toxicity (single or repeated exposure) Aspiration Hazard
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:
GHS Hazard Classification Explosive Flammable (gases, aerosols, liquids, or solids) Oxidizer (liquid, solid, or gas) Self-Reactive Pyrophoric (liquid or solid) Self-Heating Organic Peroxide Corrosive To Metal Gas Under Pressure Contact With Water Emits Flammable Gas
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
OSHA Hazard Classification In OSHA s rule there is a hazard category called Hazards not otherwise classified which is not in the UN GHS system a substance that has an identified hazard, but does not meet classification criteria for physical or health hazard under GHS These substances are covered by the current hazard communication law---so OSHA did not want GHS to result in a less protective law OSHA added pyrophorics, combustible dust, and asphyxiant s to the definition of hazardous chemical
HNOC Hazards not otherwise classified will not be required to be labeled Hazards will be disclosed on the SDS 11
Carcinogens & Trade secrets Mixture is considered to be carcinogenic if it contains .1% by volume criteria (unless the mixture has health effects at less than .1% carcinogen) Trade secret information is limited to the names of chemicals and their concentrations in mixtures. 12
GHS Labels Three standardized GHS label elements: Symbols (Hazard Pictograms) that convey health, physical, and environmental hazard information assigned to a GHS hazard class and category Signal Words Danger or Warning used to emphasize hazards and relative level of severity of the hazard and assigned to a GHS hazard class and category Hazard Statements which are standard phrases assigned to a hazard class and category that describe the nature of the hazard

NFPA and HMIS Labeling Systems While alternatives are permitted for workplace containers, the information supplied must be consistent with the revised law. Hazard classifications must be revised as necessary to conform with the final rule, and the other information provided must be revised accordingly to ensure the appropriate message is conveyed. 18

Spray Finishing There is no flash point cut off in 1910.107, so to be consistent with GHS, OSHA refers to liquids with flashpoints above 199.4 degrees F The term combustible liquids will no longer be used. 25
Flammables in Construction Temperature cut off for 1910 is 100 degree F In construction, temperature cut off is 140 degrees F Changed the definition of flammable category 3 to have flashpoints between 74 and 140 degrees F, so coverage is unchanged in construction. 26

Transition Period to the effective completion dates noted above May comply with either 29 CFR 1910.1200 (the final standard), or the current standard, or both Chemical manufacturers, importers, distributors, and employers
