OSHA's Eight Pictograms

OSHA provides eight pictograms to illustrate the different hazard classes:

Flame
Flame over Circle
Exclamation Mark
Exploding Bomb
Corrosion
Gas Cylinder
Health Hazard
Skull and Crossbones

You will learn about each of these pictograms and the classes of chemicals they represent. Note that some of these pictograms pertain to many chemicals or categories of chemicals.

This information is available on OSHA's Guidance for Hazard Determination for Compliance with the OSHA Hazard Communication Standard (29 CFR 1910.1200), as published by the U.S. Department of Labor Occupational Safety and Health Administration and Edwin G. Foulke, Jr., Assistant Secretary of Labor for Occupational Safety and Health.
