WHMIS Pictograms

WHMIS stands for Workplace Hazardous Materials Information System, a crucial safety system for handling hazardous materials in the workplace.
Pictograms are used to visually communicate the hazards associated with chemicals.

Gases Under Pressure

Example: Carbon dioxide gas.
Can explode if exposed to heat or physical shock.

Flammable Materials

Example: Methane (natural gas).
Capable of igniting in the presence of a spark or an open flame.

Oxidizing Materials

Examples: Oxygen gas and hydrogen peroxide (H2O2).
Increases fire risk when in contact with flammable materials.

Acute Health Hazards

Example: Chlorine gas.
Single exposure may lead to immediate serious injury or death.

Less Severe Health Hazards

Example: Dilute acetic acid (vinegar).
Single exposure may cause less severe effects, such as irritation or sensitivity, usually reversible.

Chronic Health Hazards

Example: Mercury.
Long-term exposure can lead to serious health issues, including cancer or organ toxicity.

Corrosive Materials

Example: Hydrochloric acid.
Capable of destroying human tissue and corroding metals.

Explosive Materials

Example: TNT (trinitrotoluene).
May self-react or explode under certain conditions.

Environmental Hazards

Example: Ammonia.
Can cause toxic effects in aquatic organisms.

Biohazardous Materials

Example: HIV virus.
Contains organisms (like bacteria or viruses) that can lead to infections or serious illnesses.

This quiz covers the Pictograms used in the Workplace Hazardous Materials Information System (WHMIS). It includes information about various chemical types, associated hazards, and safety precautions. Test your knowledge of these critical safety symbols and their meanings.
