The revised IDLH for hydrogen sulfide is 100 ppm based on acute inhalation toxicity data in humans What is the American Conference of Governmental Industrial Hygienists ACGIH recommended exposure limit for hydrogen sulfide What are the engineering controls for hydrogen sulfide What Personal Protective
The recently revised UK occupational exposure limits for H2S are designed to protect against the development of such effects The purpose of this paper is to outline the evidence and rationale underpinning the recently H 2 S is toxic at breathable concentrations between 500 1000ppm but death is not instantaneous However at concentrations of greater than 1000ppm H 2 S is rapidly lethal 1

The Occupational Safety and Health Administration OSHA defines Permissible Exposure Limits PELs to H2S gas as follows General Industry Ceiling Limit 20 ppm General Industry Peak Limit 50 ppm up to 10 OSHA Construction and Maritime Industries PEL is 10 ppm 15 mg m as an 8 hr TWA See 29 CFR 1926 55 Table 1 and 29 CFR 1915 1000 Table Z Shipyards Notes
Permissible Exposure Limit PEL OSHA sets a PEL for H S at 20 parts per million ppm as an 8 hour time weighted average TWA However a ceiling concentration of Workplace Exposure Limits OSHA The legal airborne permissible exposure limit PEL is 20 ppm not to be exceeded at any time and 50 ppm as a maximum peak not to be exceeded during
