Class D, Division 2: Poisonous & Infectious Materials - Other Toxic Effects

This division includes materials causing immediate eye and/or skin irritation as well as those which can cause long-term effects in a person repeatedly exposed to small amounts.
WHMIS
Class A: Compressed Gas

This class includes compressed gases, dissolved gases and gases liquified by compression or refrigeration .
WHMIS
Class D, Division 1: Poisonous & Infectious Materials - Immediate and Serious Toxic Effects

This division includes materials causing immediate and serious toxic effects. These materials can cause the death of a person exposed to small amounts.
WHMIS
Class C: Oxidizing Material

This class includes materials which provide oxygen or similar substances and which increase the risk of fire if they come into contact with flammable or combustible materials.
WHMIS
Class F: Dangerously Reactive Material

Class F materials can undergo dangerous reaction if subjected to heat, pressure, shock or allowed to contact water.
WHMIS
Class E: Corrosive Material

Class E materials are acid or caustic materials which can destroy the skin and/or eat through metals.
WHMIS
Class B: Flammable and Combustible Material

This class includes solids, liquids and gases capable of catching fire or exploding in the presence of a source of ignition.
WHMIS
Class D, Division 3: Poisonous & Infectious Materials - Biohazardous infectious material

This division includes materials which contain harmful microorganisms.
WHMIS
Class A: Compressed Gas
Class A materials:
-pose an explosion danger because the gas is being held in a container under pressure;
-may cause its container to explode if heated (such as what would happen in a fire);
-may also cause its container to explode if dropped.

When handling Class A materials you should:
-handle with care, do not drop container;
-keep container away from potential souces of ignition;
-store the container in designated areas.

Examples of Class A materials: gas cylinders for oxyacetylene welding or water disinfection.
Class B: Flammable and Combustible Material
Class B materials:
-will burn and are therefore potential fire hazards.
-may burn at relatively low tempertaues; flammable materials catch fire at lower temperatures than combustible materials.
-may burst into flame spontaneouly in air or may release a flammable gas on contact with water;
-may cause a fire when exposed to heat, sparks, or flames or as a result of friction;

When handling Class B materials you should:
-keep the material away from heat sources and other combustible materials;
-never smoke when working with or near the material;
-store the containers in designated areas.

Examples: white phosphorus, acetone and butane. Flammable liquids such as acetone are more easily ignited than combustible liquids such as kerosene.
Class C: Oxidizing Material
Class C materials:
-pose a fire and/or explosion risk in the presence of flammable or combustible material;
-may cause fire when they come in contact with combusitble materials such as wood;
-may react violently or cause an explosion when they come in contact with combustible materials such as fuels;
-may burn skin and eyes upon contact.

When handling Class C materials you should:
-wear the proper protective equipment, including eye, face, and hand protection and protective clothing;
-keep the material away from combustible materials;
-keep the material away from sources of ignition;
-never smoke when working with or near the material;
-store the containers in designated areas.

Examples: sodium hypochlorite, perchloric acid, inorganic peroxides.
Class D, Division 1: Poisonous & Infectious Materials - Immediate and Serious Toxic Effects
Class D, Division 1 materials:
-are a potentially fatal poisonous substance;
-may cause permanent damage if inhaled or swallowed or if they enter the body through skin contact;
-may burn eyes or skin upon contact.

When handling Class D, Division 1 materials you should:
-handle the material with extreme caution;
-avoid contact with the skin or eyes by wearing the proper protective equipment, including eye, face, and hand protection and protective clothing;
-avoid inhaling by working in well-ventilated areas and/or wearing respiratory equipment;
-wash and shower thoroughly after using;
-store the containers in designated areas.

Examples: sodium cyanide, hydrogen sulphide.
Class D, Division 2: Poisonous & Infectious Materials - Other Toxic Effects
Class D, Division 2 materials:
-are poisonous substances that are not immediately dangerous to health;
-may cause death or permanent damage as a result of repeated exposures over time;
-may be a skin or eye irritant;
-may be a sensitizer, which produces a chemical allergy;
-may cause cancer;
-may cause birth defects or sterility.

When handling Class D, Division 2 materials, you should:
-avoid contact with the skin or eyes by wearing the proper protective equipment, including eye, face, and hand protection and protective clothing;
-avoid inhaling by working in well-ventilated areas and/or wearing respiratory equipment;
-store the containers in designated areas.

Examples: acetone (irritant), asbestos (carcinogen), toluene diisocyanate (senzitizer).
Class D, Division 3: Poisonous & Infectious Materials - Biohazardous infectious material
Class D, Division 3 materials:
-may cause a serious disease resulting in illness or death.

When handling Class D, Division 3 materials, you should:
-take every measure to avoid contamination;
-handle the material only when fully protected by the proper, designated equipment;
-handle the material in designated areas where engineering controls are in place to prevent exposure.

Examples: cultures or diagnostic specimens containing salmonella bacteria or the hepatitis B virus.
Class E: Corrosive Material
Class E materials:
-cause severe eye and skin irritation upon contact;
cause severe tissue damage with prolonged contact;
-may be harmful if inhaled.

When handling Class E materials, you should:
-keep containers tightly closed;
-avoid contact with the skin or eyes by wearing the proper protective equipment, including eye, face, and hand protection and protective clothing;
-avoid inhaling by working in well-ventilated areas and/or wearing respiratory equipment.

Examples: muriatic acid, lye.
Class F: Dangerously Reactive Material
Class F materials:
-are very unstable;
may react with water to release a toxic or flammable gas;
-may explode as a result of shock, friction or increase in temperature;
-may explode if heated when in a closed container;
-may undergo vigorous polymerization.

When handling Class F materials, you should:
-keep material away from heat;
-open containers carefully, do not drop them;
-store the material in a cool, flame-proof designated area.

Examples: plastic monomers such as butadiene and some cyanides.
