Hazardous Household Product Symbols
Each symbol above may be combined with one of the three severity symbols.
NFPA Hazard Ratings
• Developed by the National Fire Protection Association.
• Provides information regarding the hazards of a material as they relate to handling, fire prevention, exposure, and control.
NFPA Hazard Ratings
WHMIS • This is a Canada wide system aimed at
reducing injuries and illness caused by exposure to hazardous materials.
• The system covers all areas of work, and chemicals.
• The key to this system is knowing and understanding the standardized labelling procedure.

Protective
Equipment
Class A: Compressed Gas
• Keep away from heat. • Do not drop or handle
roughly. • Keep the container tightly
closed. • Eg: Oxygen gas, paint cans.
Class B: Flammable and Combustible Materials • Keep away from heat. • Keep away from sources of ignition. • No smoking. • Avoid static discharge or sparks. • Keep container tightly closed. • Eg: Gasoline, acetone.
Class C: Oxidizing Material
• Keep away from heat. • Keep in a cool place. • Keep away from flammable and
combustible materials. • Avoid shock and friction. • Eg: Bleach, Hydrogen peroxide.
Class D: Poisonous and Infectious Materials Division 1: Materials Causing Immediate and
Serious Toxic Effects
• Cause death when exposed to small amounts.
• Permanent damage when exposed. • Avoid contact; use PPE’s. • Eg: Carbon monoxide, Sodium cyanide,
Hydrogen Sulphide.
Class D: Poisonous and Infectious Materials Division 2: Materials Causing Other Toxic Effects
• Damage caused over prolonged exposure.
• May be carcinogens. • Wear suitable PPE’s. • Eg: Asbestos, Mercury, Lead.

Division 3: Biohazardous Infectious Materials
• Living organisms or toxins. • Cause diseases in living things. • Organisms can live in body tissues. • Eg: AIDS/HIV virus, Hepatitis B,
Salmonella.
Class D: Poisonous and Infectious Materials Class E: Corrosive Material
• Cause severe burns to skin and other tissues.
• Can attack other materials such as clothing and metals.
• Damage is permanent. • Eg: Sulphuric and Nitric acid, Lye,
Ammonia gas.
Class F: Dangerously Reactive Material • React vigorously with water to make
a toxic gas. • Shock sensitive; “unstable’. • Vigorously join with itself
(polymerization), or break down. • Eg: Fiberglass materials.
