"How about if he connects the *blow* end of a shop vac to it? Push air
into the pipe and the methane gas away from where he's heating. "
I wouldn't be that worried about it, but doing as you suggested for 15
secs or so before starting to unsolder it sure wouldn't hurt. That
would blow any methane away from the area, at least for awhile. Of
course, this presumes the line is properly vented. If not, you may
turn the toilets into bidets.
