Actually....
I am an expert.
You only smell it once. H2S paralyzes your olfactory senses. You smell it, then you don't, then if concentration is high enough, bam you're dead.
The OSHA 15 minute Short Term Exposure Limit (STEL) for H2S is 15ppm and the lowest reported odor threshold is 0.13ppm, so you can smell it way before it is harmful....however continuous exposure can lead to olfactory fatigue.

He's (armorpl8chikn) right, you know. If you can't smell H2S, then either you are fine, or you're fucked.

Check for a pulse as a guide to how you are doing. Pulse = good, no pulse = not quite so good.
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.

Just a reminder that this started with talk about H2S from farts. I kinda doubt that fart gas kills many people. I've wanted to snuff (not sniff) farters that tainted my fresh air, to be sure.

I've built research devices that measure H2S and other toxins at low levels, that were used for peer-reviewed studies, so I'm not just spouting Google shit.
