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. |
