Tulane University - Office of Environmental Health & Safety (OEHS) Objectives An overview of the Globally Harmonized System of classification & labeling of chemicals (GHS) The 2012 revisions to the OSHA Hazard Communication Standard New requirements for labeling of chemicals New specified format for safety data sheets To become familiar with:
4
Tulane University - Office of Environmental Health & Safety (OEHS) What is GHS? A worldwide initiative to promote standard criteria for classifying chemicals Based on criteria-based definitions of physical, health, and environmental hazards OSHA has not adopted environmental aspects because it does not have jurisdiction over environmental matters
5
Tulane University - Office of Environmental Health & Safety (OEHS) OSHA HAZARD COMMUNICATION STANDARD Revised March 26, 2012 (29 CFR 1910.1200) Includes certain aspects of globally harmonized system of classification and labeling of chemicals (GHS) Purpose: To understand chemical hazards in the workplace and how to protect yourself
6
Tulane University - Office of Environmental Health & Safety (OEHS) OSHA HAZARD COMMUNICATION STANDARD Major changes include: “Right to Know” changes to “Right to Understand” Several definitions revised, changed, or deleted “Hazard determination” now “hazard classification” Significant changes to labels Specified format for safety data sheets (formerly MSDSs)
7
Tulane University - Office of Environmental Health & Safety (OEHS) OSHA HAZARD COMMUNICATION STANDARD Under the OSHA HAZCOM standard, manufacturers of chemicals are required to classify the chemicals they produce and transmit that information to customers on labels and Safety Data Sheets (SDSs)

Tulane University - Office of Environmental Health & Safety (OEHS) Chemical Classifications Aquatic Toxicity – The ability of a chemical to be hazardous to the aquatic environment Note: This pictogram is not enforced by OSHA. Environment
29
Tulane University - Office of Environmental Health & Safety (OEHS) Chemical Classifications Under the GHS classifications, chemicals are also placed into categories. (It should be noted that these categories are OPPOSITE from the numbering systems that have traditionally been used in the U.S. such as the NFPA or HMIS ratings in which 4 was the most hazardous and 0 or 1 the least hazardous.) In the GHS system, Category 1 would be the most hazardous.
30
