When is it necessary to conduct a fire watch after torch operations?

Conducting a fire watch for at least 30 minutes after the completion of torch operations is essential due to the potential for delayed ignition of combustible materials. Torch operations generate significant heat and sparks that can result in fires long after the actual work is finished. The 30-minute timeframe allows for monitoring the area to ensure that any sparks or hot materials are addressed before they can ignite any flammable substances in the vicinity.

This period is critical as embers or heat sources may remain active, posing a risk of fire if left unattended. Additionally, this proactive measure is a standard safety protocol in many fire safety regulations and guidelines, emphasizing the importance of vigilance immediately following any hot work operations. By maintaining a fire watch during this dedicated time, workers can help prevent incidents that might otherwise occur when the immediate work has concluded, but heat and hazards linger.
