H 2 S is heavier than air and therefore often collects in low-lying areas and working sites near the ground. Worth knowing: The characteristics of hydrogen sulfide Vid 100 – 200 ppm uppstår hosta och ögonbesvär. Yrsel fås inom 10 – 20 minuter och vid exponering under flera timmar kan död inträffa.

1 ppb to  Nov 23, 1990 12, 1992] ambient concentrations of 100 ppm H2S at any occupied residence, is not a potential for 100 ppm or of H2S in the gas stream. 1 ppm = 1 part of gas per million parts of air by volume. H2S levels of 100 ppm and higher are considered immediately dangerous to life and health (IDLH). 2) Twelve graphs of H2S concentration, temperature, airflow rate, etc. were printed for each day.
