H2S Hydrogen Sulfide Hazards, Precautions Safety Notes

20190730· The “parts per million” or “ppm”* scale is used to measure the concentration of H2S in the area. It divides the total into 1,000,000 parts and tells us, in parts per million, the concentration of the substance we are looking at. The smallest unit we can measure is one part per million. NOTE: (*) 1% equals 10,000 ppm
