Material Safety Data Sheet HYDROGEN SULFIDE

Jul 17, 2019 · AVAILABLE IN: English. In the past, the most widely recognized occupational exposure limits for hydrogen sulfide (H 2 S) have referenced an 8-hour TWA of 10 ppm, and a 15-minute Short-Term Exposure Limit (STEL) of 15 ppm. In February 2010, the American Conference of Governmental Industrial Hygienists (ACGIH ®) adopted a new Threshold Limit Value (TLV ®) recommendation for H 2 S, lowering the 8-hour TWA to 1.0 ppm, …

UL Develops New Standard for Gas-Fired Packaged Boiler

If a single-phase liquid is in equilibrium with a gas phase, where the gas phase H 2 S partial pressure exceeds 0.05 psia, then that liquid is also considered to be sour. If the liquid is not in equilibrium with the gas phase, then the liquid is considered sour, if this bubble point gas phase H 2 S partial pressure exceeds 0.05 psia. The presence of water is not required for a gas and/or liquid to be considered to be sour nor is there a minimum pressure to avoid designating a gas …
