One or two minutes? Lucky guy!
I once had to troubleshoot and fix an industrial PC located in a ***working*** production line in a fish canning factory. The thermometer marked 38ºC and the humidity was >95%. To make things worse, the device was placed into a massive stainless steel box that held lots of other electronics stuff.
Cue an hour or so of contortions in hellish conditions including also very high noise levels, stopping every few minutes to wipe the sweat from my eyes or going out to cool myself down.
In those conditions you feel as if your IQ has been lowered 30 points!
Afterwards, I told the management that I'd never work in those conditions again. They pointed out that the workers in the line worked in those conditions in 4 hours turns and I pointed out that said workers were walking over a metal grid that provided them with a steady flow of dry, cool air; otherwise, they'd be suffering half a dozen cardiac arrests per day!.
They didn't call me again, and good riddance! 8^)
