Hazard Reporting

Report any potential hazard (glowing fuel, visible sparks, electrical shocks, defective grounding/bonding, fluid leaks) to supervision.

Recoverable Products

Handle recoverable products (fuel/oil spills) according to federal, state, and local pollution control laws (AFI 23-201, TO 42B-1-23) through base fire department and civil engineering.

Fuel/Oil Spills

Report spills to base fire department and civil engineering pollution control to comply with local directives.
