Always use _____ to put out a tire fire.

Always use _____ to put out a tire fire.

• A. A Class A fire extinguisher
• B. Water
• C. A multi-class fire extinguisher
• D. Carbon dioxide

Answer: (B)

When a tire fire is involved, the priority is to remove heat from the burning material so it cannot continue to burn or reflash. Water excels at this because it absorbs a large amount of heat as it turns to steam, rapidly cooling the rubber, steel belts, and other components. This cooling effect helps prevent the fire from spreading to adjacent tires and reduces the chance of rekindling once any flames die down. Other extinguishing agents don’t provide the same deep cooling for a large mass of burning tires. A Class A extinguisher targets ordinary combustibles like wood and paper but doesn’t address the heavy, solid mass of tires as effectively. Carbon dioxide displaces oxygen but doesn’t cool embedded embers or penetrate the tire mass, so it’s less reliable for preventing reignition. A multi-class extinguisher covers various types of fires, but it still relies on agents that won’t cool as efficiently as water for a tire load. So, water is the best option because its cooling power directly reduces heat and stops the fire from continuing or resurfacing.
