What types of flammable liquid are classified under Class 3?

• A. Liquids with flash point below 60°C (140°F)
• B. Liquids that are non-combustible
• C. Liquids that are solid at room temperature
• D. Liquids with a flash point above 200°C (392°F)

Answer: (A)

Class 3 flammable liquids specifically includes those liquids that have a flash point below 60°C (140°F). The flash point is the lowest temperature at which a liquid can form an ignitable mixture in the air, and liquids with flash points below this temperature are considered to pose a significant fire hazard. This classification is vital for the safe storage, transport, and handling of these substances, as it requires stringent precautions to prevent fire and explosion risks. The other types mentioned—non-combustible liquids, solids at room temperature, and liquids with a high flash point—do not fall under Class 3 because they either do not ignite easily or simply do not meet the criteria for flammability as defined by the regulations for dangerous goods.
