A Fire Watch/Hole Watch is a crucial safety role monitoring hazardous work, like welding (Fire Watch) or confined space entry (Hole Watch), to prevent fires and rescue personnel by watching for hazards, sounding alarms, using firefighting equipment, and halting dangerous activities, with undivided attention to safety and clear communication. This role requires specific training, vigilance, and authority to stop work, ensuring readiness to extinguish small fires or call emergency services immediately during the work and for a period afterward.
