A fire-watcher is best described as:

• A. An individual who can fight fires and perform fire-training duties in the case of a fire hazard
• B. A person who only monitors for smoke and doesn't engage in firefighting
• C. A supervisor who schedules welding shifts
• D. A welder who operates heavy equipment

Answer: (A)

During hot work like welding, a fire watch exists to prevent fires and respond quickly if one starts. The best description is someone who can fight fires and perform fire-training duties in case of a fire hazard because that captures both the proactive and reactive aspects of the role: they are ready to use extinguishing equipment, suppress small fires, and participate in fire safety training and procedures. This goes beyond merely watching for smoke, which would not ensure an immediate firefighting response. It also isn’t a supervisory duty or a welding-operator task, which are unrelated to active fire safety responsibilities.
