When is an additional F-60 fire guard required at a torch operation site?

An additional F-60 fire guard is required when working below a torch operation that could produce sparks because the potential for sparks to ignite nearby combustible materials significantly increases in that scenario. The role of the fire guard is to continuously monitor the area for any signs of fire and to take immediate action if a spark produced by the torch operation poses a threat. This precaution ensures that flammable materials or other potential ignition sources in the vicinity are adequately protected, thereby enhancing overall safety at the torch operation site.
