G. , Am. J. Ind. 7 The Myth of Harmless Knockdown It is sometimes stated in the literature, especially older reports, that if the victim of H2S poisoning survives, then recovery is prompt and complete [42,51]. There are very many documented cases proving this to be a false assumption [6,49,83]. It is possible that this confusion is the result of conflating two things: • A very large fraction of fatalities occur on the scene. • “Knockdown”—immediate, temporary unconsciousness caused by H2S. 1 Fatalities Occurring on the Scene A very large fraction of fatalities do occur on the scene.

Who may perform the hazard assessment? ) • What tests must be performed before entry? • What must be monitored while workers are in the space? Confined Spaces 13 • Under what conditions can workers enter the space? • Power lockout/tag out. • Mandatory personal protective equipment (PPE). • Standby persons. • Communication routines. • Rescue procedures and equipment. • Training of workers entering the space, standby persons, and rescue workers. • Calibration and maintenance of test equipment, PPE, and rescue equipment.

3. The ACGIH’s threshold limit value (TLV®) for H2S is 1 ppm, 8-hour timeweighted average (before 2010, 10 ppm), and 5 ppm short-term exposure limit (before 2010, 15 ppm). The National Institute for Occupational Safety and Health (NIOSH) has determined the concentration that should be regarded as immediately dangerous to life or health to be 100 ppm. NIOSH has also set a Recommended Exposure Limit (REL) of 10 ppm, which should not be exceeded during any 10-minute work period. 1 Community versus Workplace Standards Community standards or odor nuisance statutes are intended to prevent or ameliorate smells that interfere with the well-being of community residents.
