Does standard firewatch require two people one on the torch and one doing the firewatch?

My knowledge base does not contain specific documentation on firewatch safety regulations mandating two personnel for fire watch during torch operations. However, I can provide general safety guidance based on industry best practices.

Generally, a fire watch is required when welding, cutting, or heating operations are performed in locations where normal fire prevention precautions are not sufficient. The fire watch personnel should be trained in the specific fire hazards anticipated and in the use of the firefighting equipment provided.
