Which of the following is NOT a role of the responsible person during hot work operations?

In the context of hot work operations, the responsibilities of the responsible person are primarily focused on ensuring safety and compliance with fire prevention measures. While they may need to communicate relevant information to supervisors or required parties, acting as a spokesperson is not a core responsibility.

The responsible person's main duties include issuing hot work authorizations, which involve assessing the work area and conditions before allowing hot work to proceed. They also monitor fire extinguishers to ensure that appropriate equipment is readily available and functional in case of an emergency. Additionally, they are tasked with ensuring that all safety protocols are adhered to during the operations, which includes verifying that necessary precautions are taken to prevent fires or accidents.

Acting as a spokesperson implies a role that involves public relations or communication beyond the immediate context of safety management during hot work, which is why this choice is not aligned with the primary functions expected of a responsible person in these scenarios.
