x (ppm) = 10000 ⋅ 1.7% = 17000 ppm. Percent to ppm … In the past, the most widely recognized occupational exposure limits for hydrogen sulfide (H2S) have referenced an 8-hour TWA of 10 ppm, and a 15-minute STEL of 15 ppm. In February 2010, the American Conference of Governmental Industrial Hygienists (ACGIH®) adopted a new threshold limit value (TLV®) recommendation for H2S, lowering the 8-hour TWA to 1.0 ppm, and the STEL to 5.0 ppm. Release of H2S: All personnel working in an area where concentrations of Hydrogen Sulfide may exceed the 10 Parts Per Million (PPM) should be provided with training before beginning work assignments. Potential Hazard: H2S exposure greater than the Permissible Exposure Limit (PEL). Possible Solutions: ppm to percent converter How to convert percent to ppm.
