WHMIS Classification Symbols

Controlled products are divided into six classes; all have a distinctive hazard symbol assigned to assist in identifying the associated
risks.
Safe Handling Measures
Any product that is normally a gas at room  Keep container closed tightly and ensure valves Compressed
temperature and kept in a container under  If ruptured or broken may rocket or torpedo  Keep from heat or changes in temperature.  Must be secured and may require flashback  Liquefied compressed gas can cause severe Includes any solid, liquid or gas that will burn.  Keep away from heat or sources of ignition Flammable &
 May burn at relatively low temperatures Combustible
 May burst into flame spontaneously when in  Avoid static discharges or impacts that could Material
 May release flammable gas when in contact  May cause a fire if exposed to heat, sparks, Oxidizers cause other substances to burn or Oxidizing
