![]() Self-reactive substances and mixtures – Type B* The WHMIS 2015 signal words and hazard statements for flammable gases, aerosols, liquids and solids are: Hazard Class and Categoryīelow are the signal words and hazard statements for the other WHMIS 2015 hazard classes and categories that are assigned the flame pictogram. What signal words and hazard statements are used? Back to top When flammable products burn, hazardous gases and vapours can be produced (e.g., carbon monoxide, hydrogen cyanide and nitrogen oxides). You also need to consider the potential for hazardous thermal decomposition and combustion products. Once the vapour ignites, the flames or fire can “flash-back”, meaning that the flames travel back to the container or source of the flammable liquid and an explosion can occur. In this case, the vapour can spread a long distance along the ground or floor and eventually be ignited by a distant spark, flame or other source of heat. Flashback – the vapour of most flammable liquids is heavier than air.Release of the static charge from the liquid can ignite flammable products. This charge can occur and accumulate when flammable liquids are poured, pumped, filtered, agitated, stirred or flow through pipes, and these actions can act as an ignition source. Accumulation of static charge – static electricity is the electric charge generated when there is friction between two things made of different materials or substances. ![]() The following hazards are also associated with flammable liquids: It is very important when working with flammable products that these three elements are not present together in the right amounts at any time. heat (e.g., an ignition source such as a spark).a source of fuel (e.g., the flammable product),.Hazardous products with the flame pictogram can be a fire or explosion hazard in the workplace.įor a fire to occur, three elements must be together at the same time and in the right proportions: What are the hazards of products that have a flame pictogram? Back to top Type B is assigned two pictograms – the flame and the exploding bomb. *Note that the most severe hazard category in the self-reactive substances and mixtures hazard class (Type A) is assigned the exploding bomb pictogram. Organic peroxides – Type B*, Type C, Type D, Type E and Type F.Substances and mixtures which, in contact with water, emit flammable gases – Category 1, Category 2 and Category 3.Self-heating substances and mixtures – Category 1 and Category 2.Self-reactive substances and mixtures - Type B*, Type C, Type D, Type E and Type F.There are other hazard classes that use the flame pictogram but products with these hazards are not commonly found in workplaces: Flammable solids – Category 1 and Category 2.Flammable liquids – Category 1, Category 2 and Category 3.Flammable aerosols – Category 1 and Category 2.In most workplaces, you will see this pictogram used on hazardous products for the following hazard classes: Which hazard classes use the flame pictogram?
