It is extremely flammable and highly toxic. Hydrogen sulfide is used or produced in a number of industries, such as. Oil and gas refining; Mining; Tanning; Pulp and paper processing Chart corrected 1/12/2002, due to e-mail from a victim of H2S poisoning 0.03 ppm: Can smell. Safe for 8 hours exposure 4 ppm: May cause eye irritation. Mask must be used as it damages metabolism. 10 ppm : Maximum exposure 10 minutes. Kills smell in 3 to 15 minutes.

12/08/1999 09:02:47 … The H2S Analyser can measure H2S concentrations from 0 to 250 mg/kg (ppm) in the liquid phase. 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. 2017-12-12 Power Consumption V+ = 3.0 V 0.15 12 mW CROSS SENSITIVITY The following table lists the relative response of common potential interfering gases, and the concentration at which the data was gathered.

CONVERT PPM TO MG/M 3 H2S has a wide flammability limit between 4.3 and 46 Vol%. Exposure can cause mild headaches, eye / nose / throat / respiratory system irritation to very severe, loss of consciousness and death. It is an irritant and chemical asphyxiating, i.e. it has effects on both oxygen utilization and the central nervous system. Measurement Of H2s:.
