What is the purpose of a fire watch in welding operations?

• A. To inspect welds for porosity after cooling.
• B. To document welding activity for safety audits.
• C. To monitor for sparks and potential fire hazards and to take immediate action if a fire starts.
• D. To measure weld temperature during the process.

Answer: (C)

Fire watch is there to prevent fires during welding by actively looking for sparks, heat, and other ignition sources and being ready to act immediately if a fire starts. Welding can fling sparks and molten metal, and nearby flammable materials can ignite quickly, so a trained person monitors the area, keeps extinguishing equipment on hand, and can stop work or alert others as needed. This role also includes knowing what to do to suppress a fire and staying in the area long enough after welding to ensure no smoldering ignition remains. The other tasks—inspecting welds after cooling, documenting activity for audits, or measuring temperature during the process—are important safety or quality duties, but they aren’t the primary purpose of a fire watch.
