How long should a fire watch be conducted after extinguishing a vehicle fire?

The correct duration for conducting a fire watch after extinguishing a vehicle fire is typically 45 minutes. This time frame is based on the understanding that vehicle fires can sometimes reignite due to residual heat or smoldering materials that may not have been fully extinguished. A fire watch during this period ensures that any potential flare-ups are quickly detected and addressed, enhancing safety for both the responders and the public.

Extending the fire watch beyond the 45-minute mark may not be necessary unless there are specific conditions or concerns present, such as the possibility of flammable materials near the site or adverse environmental conditions that could contribute to rekindling. In practice, the 45-minute guideline balances vigilance with operational efficiency, allowing the fire watch personnel to manage their time effectively while ensuring safety.

Understanding the rationale behind this duration is crucial for effective fire management and response protocols.
