What is the purpose of a welding fire watch, and when is one typically required?

• A. To monitor PPE compliance and perform inspections.
• B. To detect and suppress fires from hot work; required for hot-work operations or when welding near flammable materials.
• C. To oversee welding speed and productivity.
• D. To supervise lunch breaks.

Answer: (B)

A welding fire watch exists to spot and suppress fires that can start from hot work, such as welding. Sparks, heat, and molten metal from welding can ignite nearby flammable materials, so having a trained person dedicated to monitoring for fire and ready to respond quickly reduces the risk of a small spark turning into a larger fire. This duty is typically required for hot-work operations or whenever welding is performed near flammable materials, in line with safety rules or site policy. The person on fire watch should have access to extinguishing equipment, know how to use it, and stay on site for a period after the work to ensure no smoldering or reignition occurs.
