Hazardous Material Symbols
compressed gas symbol CLASS A: COMPRESSED GAS
This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration.
ammable and combustible material symbol CLASS B: FLAMMABLE AND COMBUSTIBLE MATERIAL
This class includes solids, liquids, and gases capable of catching fire in the presence of a spark or open flame under normal working conditions.
idizing material symbol CLASS C: OXIDIZING MATERIAL
These materials increase the risk of fire if they come in contact with flammable or combustible materials.
isonous and infectious meterial Division 1: Materials Causing Immediate and Serious Toxic Effects symbol CLASS D: POISONOUS AND INFECTIOUS MATERIAL
Division 1: Materials Causing Immediate and Serious Toxic Effects
These materials can cause death or immediate injury when a person is exposed to small amounts. Examples: sodium cyanide, hydrogen sulphide
isonous and infectious material division 2: materials causing other toxic effects symbol CLASS D: POISONOUS AND INFECTIOUS MATERIAL
Division 2: Materials Causing Other Toxic EFFECTS
These materials can cause life-threatening and serious long-term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts.
ASS D: POISONOUS AND INFECTIOUS MATERIAL Division 3: Biohazardous Infectious MATERIAL symbol CLASS D: POISONOUS AND INFECTIOUS MATERIAL
Division 3: Biohazardous Infectious Material
These materials contain an organism that has been shown to cause disease or to be a probable cause of disease in persons or animals.
ASS E: CORROSIVE MATERIAL symbol CLASS E: CORROSIVE MATERIAL
This class includes caustic and acid materials that can destroy the skin or eat through metals. Examples: sodium hydroxide, hydrochloric acid, nitric acid métaux.
ngerously reactive material symbol CLASS F: DANGEROUSLY REACTIVE MATERIAL
These products may self-react dangerously (for example, they may explode) upon standing or when exposed to physical shock or to increased pressure or temperature, or they emit toxic gases when exposed to water.
