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.

Best Guide to H2S Monitors (Hydrogen Sulfide) – Forensics …

06/07/2021· A typical H2S Gas monitor presents hydrogen sulfide readings in ppm, parts per million. The typical scale of concentration for any gas is %vol. The means how much % of the air volume is taken up in volumetric measure by the gas. There are other measures based on weight and mols, but for now, this is not important as gas detection primarily involves readings on a volumetric basis, hence %vol. …
