Hydrogen sulfide is a highly flammable, explosive gas, and can cause possible life-threatening situations if not properly handled. In addition, hydrogen sulfide gas burns and produces other toxic vapors and gases, such as sulfur dioxide.

Jan 11, 2024 · OSHA Construction and Maritime Industries PEL is 10 ppm (15 mg/m³), as an 8 hr TWA. See 29 CFR 1926.55 Table 1 and 29 CFR 1915.1000 Table Z-Shipyards. Health factors: See NIH-NLM PubChem. ACGIH: Documentation of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs) - Hydrogen sulfide.

Cal/OSHA enforces its PELs in workplaces under its jurisdiction. Cal/OSHA has established occupational exposure limits for compounds not included in the OSHA Z Tables. Please see Cal/OSHA Table AC-1 for additional limits, the most current limits, and other designations such as skin absorption.

Aug 19, 2024 · Permissible Exposure Limit (PEL): OSHA sets a PEL for H₂S at 20 parts per million (ppm) as an 8-hour time-weighted average (TWA). However, a ceiling concentration of 50 ppm is allowed for up to 10 minutes if no other measurable exposure occurs during the work shift.

Description of Substance: Colorless gas with a strong odor of rotten eggs. LEL: 4.0% (10% LEL, 4,000 ppm) Original (SCP) IDLH: 300 ppm.

Colorless gas with a strong odor of rotten eggs. [Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H 2 S. Shipped as a liquefied compressed gas.] Strong oxidizers, strong nitric acid, metals.

Permissible exposure limit (PEL) (10 ppm for H2S)—An exposure limit that is set and enforced by OSHA. The PEL is the maximum amount or concentration of a chemical or agent that a worker may be exposed to.

Sep 28, 2011 · OSHA has accordingly established an 8-hour TWA limit for hydrogen sulfide of 10 ppm and a short-term limit of 15 ppm. These levels have been demonstrated to be effective in preventing irritation and conjunctivitis in the workplace (Poda and Aiken 1966/ Ex. 1-115).

Hydrogen sulfide is included in these lists of toxic and reactive highly hazardous chemicals and is considered to present a potential for a catastrophic event at or above 1500 pounds. Hydrogen sulfide exposure addressed in specific OSHA standards for …
