What additional precaution must be taken when conducting hot work operations?

When conducting hot work operations, establishing a fire watch is critical for ensuring safety. A fire watch involves having a trained individual present to monitor the area for any signs of fire or hazards while the hot work is being performed. This person is responsible for being on the lookout for potential ignition sources and is prepared to take immediate action in case a fire does occur, such as using a fire extinguisher or alerting emergency services.

The importance of having a fire watch cannot be overstated, as hot work can generate sparks and heat that may ignite flammable materials nearby. A dedicated fire watch provides an additional layer of protection, complementing other safety measures such as ensuring the area is free from combustible materials and using appropriate personal protective equipment.

In contrast, while options like using a cooling spray, wearing heat-resistant gloves, or performing operations at night can contribute to overall safety, they do not address the immediate risk of fire in the same manner that a fire watch does. Thus, establishing a fire watch is a fundamental and necessary requirement in hot work operations.
