H2s Ppm Limits, Sep 30, 2024 · Learn about hydrogen sulfide (H₂S) hazards, health effects, safety measures, and regulations to ensure safe handling and workplace protection. Workers are primarily exposed to hydrogen sulfide by breathing it. Colourless, flammable, and toxic even at low concentrations, H₂S has earned a notorious reputation across high-risk industries. Permissible Exposure Limit (PEL): The OSHA exposure limit for H2S is 10 parts per million (PPM) over an 8-hour time-weighted average. Where the potential exists for exposure over 1 ppm, use a NIOSH approved full facepiece powered-air purifying respirator with an acid gas cartridge which is specifically approved for Hydrogen Sulfide. 1000 Table Z-2) and is not to be exceeded at any time during an 8-hour shift, except if the exposure is 50 ppm for no more than 10 minutes in an 8-hour shift so long as no other measurable exposure occurs. Exposure to very high concentrations can quickly lead to death. The RAVS is your written H2S program. Short-term (also called acute) symptoms and effects are shown below: H2S, or hydrogen sulfide, is a colorless, flammable gas best known for its strong rotten-egg smell.
