What are H2S Exposure Limits? - Definition from Safeopedia

· H2S (Hydrogen Sulfide) is a highly toxic gas that can kill or seriously harm human health when exposed to it, even at low concentrations like 10 parts per million (ppm). H2S is normally found in the oil and gas fields (well drilling, servicing, work over, down hole maintenance, plug and abandonment procedures etc.) or in the storage tanks and transports of such substances that releases H2S.
