The immediate concern with combustible liquid spills is to

• A. Apply AFFF to the combustible liquid
• B. Prevent ignition
• C. Dike storm drains along collection route
• D. Ignite fuel to allow the combustible materials to burn off

Answer: (B)

Preventing ignition is the immediate concern with a combustible liquid spill. Combustible liquids release vapors that can form flammable mixtures, and those vapors can ignite from static electricity, sparks, hot surfaces, or other ignition sources. The quickest way to reduce risk is to remove ignition sources and stop or control the release, then contain and recover the liquid as a follow-up step. Using firefighting foam first is inappropriate because foam is for extinguishing fires, not for preventing ignition during a spill. Containing the spill by diking drains is important for environmental protection, but it doesn’t directly address the fire hazard. Igniting the fuel to burn it off is dangerous and must be avoided.
