A fire watch is necessary during crane operations primarily to monitor and respond to potential fire hazards, especially during hot work activities such as welding, cutting, grinding, or other operations that can produce sparks or heat. The role of a fire watch is crucial because these activities can ignite flammable materials nearby, leading to significant safety risks and potential injuries.

In situations where hot work is being performed, having a dedicated person to keep an eye on the work environment can help detect any early signs of fire, allowing for prompt action to extinguish small fires before they escalate. This proactive measure enhances the overall safety of the operation and ensures that workers remain protected while engaging in tasks that have inherent risks associated with fire.

The other choices represent important aspects of crane operations and workplace safety but do not directly address the specific need for a fire watch during hot work. Supervising the crane operator, ensuring compliance with regulations, and inspecting rigging equipment are all essential protocols, but they do not specifically target fire risk mitigation, which is the primary focus of a fire watch.
