Which hazard class includes flammable liquids?

• A. Class 1
• B. Class 2
• C. Class 3
• D. Class 4

Answer: (C)

Flammable liquids fall under Class 3 of the hazard classification system. This class specifically pertains to materials that can ignite easily and burn rapidly. The defining characteristic of flammable liquids is that they have a flash point of 60 °C (140 °F) or below, which signifies the lowest temperature at which the liquid can vaporize to form an ignitable mixture in air. The importance of this classification lies in the properties of flammable liquids and the potential risks they pose during transportation and storage. Proper handling, labeling, and emergency response measures are essential to ensure safety when dealing with materials classified as Class 3. In contrast, other classes address different types of hazards. Class 1 includes explosives, Class 2 encompasses gases (including flammable, non-flammable, and toxic gases), and Class 4 is focused on solids that are flammable or spontaneously combustible. Each class is distinguished by unique chemical properties and associated risks.
