Commercial drivers must recognize and execute specific emergency procedures depending on the source of a vehicle fire. Match each commercial vehicle fire scenario on the left with its correct initial response procedure on the right.
- Engine compartment fireKeep the hood closed and aim a dry chemical extinguisher through the grille or louvers.
- Burning dual tireCool extensively with water and isolate or remove the wheel assembly if safe.
- Electrical cab system fireCut the electrical supply by turning off the ignition or master switch, and use a dry chemical extinguisher without water.
- Spilled fuel fire on the roadwaySweep a B:C dry chemical extinguisher across the base of the flames, avoiding water to prevent spreading.
Answer
Engine compartment fire matches keeping the hood closed and spraying through louvers; Burning dual tire matches cooling with water and isolating the tire; Electrical cab system fire matches turning off the power switch and using dry chemical without water; Spilled fuel fire matches sweeping a B:C extinguisher at the base of the fire.
Each fire source requires a specific countermeasure: engine fires require containment without opening the hood; tire fires require cooling with water; electrical fires require de-energizing the circuit and using non-conductive agents; and liquid fuel fires require dry chemical extinguishing at the base of the fire.
