WHMIS: Workplace Hazardous Materials Information System
- Pictograms indicate the type of hazard associated with a material.
- The flame symbol indicates flammable materials.
- The symbol showing material corroding a hand indicates corrosive materials.
- Biohazardous infectious materials are indicated by a circle with a specific symbol.
- Oxidizers are indicated by a flame over a circle.
- Health hazards are represented by a figure with damage to the torso
- The exclamation point indicates a harmful or irritant material.
- Compressed gasses are indicated by a gas cylinder.
- An exploding bomb represents explosive materials.
- The skull and crossbones indicate toxic materials.
Hazard Symbol Meanings
- An exploding bomb warns of explosion or reactivity hazards.
- A flame signifies fire hazards.
- A flame over a circle indicates oxidizing hazards.
- A gas cylinder identifies gases under pressure.
- Corrosion indicates corrosive damage to metals, skin, and eyes.
- Skull and crossbones mean that the material can cause death or toxicity with short exposure to small amounts.
- Health hazard symbol suggests the material may cause or is suspected of causing serious health effects.
- The exclamation mark indicates a material may cause less serious health effects or damage the ozone layer.
