NEW Globally Harmonized System of Classification and Labeling of Chemicals (GHS) Intent - To provide employees with information to help them make knowledgeable decisions about chemical hazards in their workplace Timeline December 1, 2013: Train employers on the new label elements and SDS format. December 1, 2015: Distributors may ship products labeled by manufacturers under the old system until December 1, 2015. June 1, 2016: Update alternative workplace labeling and hazard communication program as necessary. Provide additional employee training for newly identified physical or health hazards.
“Globally Harmonized System” created by the United Nations Also known as “GHS” A system for standardizing chemical classification and labeling for world-wide implementation Labels: Signal words (Danger/Warning) Hazard statements Precautionary statements Pictograms (9) SDS-16 categories Training http://www.osha.gov/Publication s/HazComm_QuickCard_Safet yData.html http://www.osha.gov/Publication s/HazComm_QuickCard_Safet yData.html
New SDS (formerly MSDS) format: http://www.osha.gov/Publications/HazComm_QuickCard_SafetyDat a.htmlhttp://www.osha.gov/Publications/HazComm_QuickCard_SafetyDat a.html Hazard classification of chemical hazards Revised labeling provisions that include requirements for: requirements for: – Standardized signal words Pictograms Hazard statements Precautionary statements
GHS looks at: o Class-nature of hazard o Category-degree of severity A chemical can pose a “physical hazard” or a “health hazard” Physical hazards are exhibited by certain chemicals because of their physical properties (e.g. flammability, reactivity, etc.) These chemicals fall into the following classes: o Flammable liquids or solids o Combustible liquids o Compressed gases o Explosives Organic peroxide: May react explosively to temperature/pressure changes Oxidizers: Chemicals that initiate or promote combustion in other materials Pyrophoric materials: May ignite spontaneously in air temperatures of 130ºF or below Unstable materials Water reactive materials
Health hazard - Occurs when a chemical produces an acute or chronic health effect on exposed employees
