(Used with permission of WorkSafeBC)Ĭhemicals that cause burns are identified by the symbol shown in Figure 12 and are also part of Class E, corrosive material. This division covers caustic or acid materials, which can destroy the skin or eat through metals (Figure 11).Įxamples: cleaning agents and degreasing agents. Corrosive material symbol (Used with permission of WorkSafeBC) It applies to materials that contain harmful micro-organisms.Įxamples: Some foods that can support bacterial growth such as salmonella bacteria or E. Biohazardous infectious materials symbol (Used with permission of WorkSafeBC)īiohazardous infectious materials are in this division (Figure 10). Others can cause long-term effects in a person who is repeatedly exposed to small amounts.Įxamples: Pesticides and rodenticides. Some cause immediate skin or eye irritation. In this division are materials that cause other toxic effects (Figure 9). Other toxic effects symbol (Used with permission of WorkSafeBC) They can cause the death of a person exposed to small amounts.Įxamples: Cleaning chemicals. This division covers materials that cause immediate and serious toxic effects (Figure 8). Immediate and serious toxic effects symbol (Used with permission of WorkSafeBC) There are three divisions in Class D: Division 1, Division 2, and Division 3. Class D – Poisonous and Infectious Materials In this class are unstable substances that combine with oxygen and increase the risk of fire if they come in contact with flammable or combustible materials (Figure 7).Įxamples: Cleaning chemicals. Oxidizing material symbol (Used with permission of WorkSafeBC) ![]() Take the necessary precautions to ensure using these flammable liquids safely. Fire extinguishers should also be on hand and in operating order. When concentrations of flammable liquids are present, there is a great risk of these fumes being ignited by an open flame or spark. Flammable liquids such as sterno is more easily ignited than combustible liquids such as lamp oil for fondues. Division 6: reactive flammable materialsĮxamples: White phosphorus, acetone, and butane.In this class are solids, liquids, and gases capable of catching fire or exploding in the presence of a source of ignition (Figure 6). ![]() Flammable and combustible material symbol (Used with permission of WorkSafeBC) Class B – Flammable and Combustible Material Figure 6. Whether the tank is full or empty, it still contains tremendous pressure. Protective caps should be kept on the tanks when they are not in use. Bottles of compressed gas, propane, and other gases must be handled with extreme care. The explosion symbol is often found on small consumer containers of products stored under pressure. Explosion symbol (Used with permission of WorkSafeBC)Īlthough not a part of the WHMIS 1988 program, this symbol (Figure 5) is a part of the new WHMIS 2015 program and the GHS. This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration (Figure 4).Įxamples: Gas cylinders for barbeques, small blow torches, and butane lighters all contain compressed gas. Compressed gas symbol (Used with permission of WorkSafeBC) These are used on products that are usually sold to individual consumers in small quantities. The hazard symbols in triangles are set by Consumer and Corporate Affairs. These are generally found on products that are usually sold in large quantities to manufacturers and contractors, and they must carry the correct labels. The symbols in circles indicate hazard classes and divisions set by WHMIS. Listed below are symbols used to identify hazardous materials, which all workers should be familiar with. ![]()
