What a timely topic.
What you guys have been describing is fire-watch duty.
In a Nuke plant, if there is any torch cutting, welding or grinding to be done.
There has to be a qualified person to watch the area as you weld.

I'll be welding/grinding on a dock ramp tomorrow morning about a foot over the water.
Someone will be with me, to keep an eye on things, the whole time.
