Which statement describes Class 3 liquids?

• A. Class 4
• B. Class 3
• C. Class 5
• D. Class 2

Answer: (B)

Liquids are classified by flash point to indicate fire risk. Class 3 liquids are flammable liquids, defined by having a flash point at or below 60°C (140°F). Because their vapors can ignite at relatively low temperatures, they present a higher fire hazard and demand careful handling and storage—keep them away from heat and ignition sources, use approved flammable-liquid containment, bond and ground during transfers, and ensure good ventilation. The other hazard classes describe different risks (solids that ignite, oxidizers that support combustion, or gases), not flammable liquids. In a correctional facility setting, this means being especially vigilant with fuels, solvents, and certain cleaners, labeling them correctly, and having appropriate spill and exposure controls. So the statement that these liquids are flammable liquids with a low flash point is the most accurate description.
