If we’re doing the “actually” thing, then actually if someone goes down from suspected h2s poisoning and you go check for a pulse without out an airpac, you’re gonna be laying there beside them, 100 ppm can be a lethal dose if not brought into fresh air, we’ve worked on wells that were up over 40,000 ppm, h2s ain’t something to be fucked with, but also don’t just google shit and start spouting shit, we’ve had monitors going bat shit crazy and they were reading anywhere from 40 to 60 ppm, we just minded the wind, took some Tylenol for the headache we was about to have and kept rolling.
