NB: the olfactory perception is detectable at very low concentration but does not constitute a sufficient alert threshold because it diminishes until disappearing as the gas concentration increases (olfactory sideration effect).

I guarantee that the staff have detectors in the installations concerned. It is true that this generally does not smell of rose, and that it is therefore difficult to spot this additional odor - unlike the pet in the salon of the Marquise!
But we agree: it is not a fart that will dissipate very quickly that will poison us, nor a stinking ball ... As it is not CO2 of a Coke or when its making its bread that will suffocate us ...
I followed (in) training on the job on the subject with training in the use of H2S detectors.
We are in an anaerobic bacterial mechanism = rather in ** humid ** premises at a sufficient temperature for the development of bacteria and lack of ventilation of the premises ... this is a common situation with us, and we had a case (mild) H2S intoxication (which triggered the flurry of training ...)
Very little risk in our garden activities.
