What fire watch requirements are specified in NFPA 51B?

[NFPA_51B]

NFPA 51B outlines strict fire watch requirements to prevent fire incidents during and after hot work:

When Required:
A fire watch must be assigned whenever hot work is conducted in areas where fire hazards exist—such as locations with combustible materials, flammable vapors, or dust.

Duration:
The fire watch must be maintained during the hot work and for at least 30 minutes after completion to monitor for smoldering fires or sparks.

Training:
Fire watch personnel must be trained and familiar with fire hazards, the use of portable fire extinguishers, and emergency procedures.

Equipment:
Fire watchers must have immediate access to suitable fire extinguishing equipment such as fire extinguishers or hoses.

Duties:
Their primary responsibility is to continuously monitor the area for signs of fire and take immediate action if a fire starts, including alerting emergency services and attempting initial fire suppression.

Communication:
Fire watch personnel should maintain effective communication with the hot work operators and be empowered to halt work if unsafe conditions arise.
