600 ppm h2s

Kills smell in 3 to 15 minutes. Causes GAS EYE and throat injury. Reacts violently with dental mercury amalgam fillings. Percentages and ppm in gases are normally based on molar ratios (solids are usually mass ratios, liquids may be mass, volume or even mass/volume). So it is 9.36%; however 1% = 10000 ppm (1% of one million parts), so 93600 ppm. GASCO Hydrogen Sulfide (H2S) Calibration Gas also known as Cal Gas, is used for the Calibration and Maintenance of Gas Detectors and Sensors. All of our GASCO Calibration Gas Cylinders ship with a Certificate of Analysis (COA).

H2S is efficiently purged from the test sample by a combination of heat and agitation, and is measured by a proprietary advanced gas specific detector.

Normal ranges in sour gas facilities usually range between 1 to 3 ppm levels OSHA Permissible Exposure Limits (PEL) for H2S are listed below for conditions stated: General industry - up to 20 ppm. Exceptions - may exceed 20 ppm if no other exposures during 8 hour work shift, but not more than 50 ppm for a single time exposure for 10 minutes. Construction industry - up to 10 ppm.

Det är politiskt dyrt att begränsa den valfrihet vi vant oss vid.
