Water can be used to fight which type of fire on a vehicle?

• A. Tires
• B. Electrical fires
• C. Gasoline fires
• D. Hydraulic fires

Answer: (A)

Water is effective for tire fires because burning tires involve solid rubber, and the main goal is to remove heat from the material to stop the combustion. Water has a high heat absorption capacity, so applying it cools the rubber and the wheel assembly, slowing or halting the chemical reactions that keep the fire going. By cooling the tires, you reduce the chance of the fire spreading to surrounding parts of the vehicle and help prevent re-ignition as the heat drops. Water is not the right choice for electrical fires, because it conducts electricity and can endanger anyone involved if live components are touched or nearby. For gasoline fires, water can actually cause trouble by causing the liquid fuel to spread or float to other areas, spreading the flame rather than smothering it. Hydraulic fires involve oil-based fluids that don’t mix well with water; water won’t effectively suppress those flames and can simply disperse the fuel. So, when facing a fire on a vehicle where the burning material is solid rubber from tires, water’s cooling effect makes it the most appropriate option among the choices given.
