Hydrogen Sulfide - H2S

Hydrogen Sulfide - H2S

Key information on hydrogen sulfide or " hydrogen sulfide " (H2S) such as its physical characteristics, its effects on health, the means of detecting it (H2S gas detector) as well as the appropriate respiratory protection equipment (gas mask or assisted ventilation device with type B anti-gas filter ).

Main characteristics of hydrogen sulfide (H2S)

Hydrogen sulfide (H2S), also called " hydrogen sulfide ", is a gas naturally present on earth. This gas results from the decomposition of organic and bacterial matter, which explains its massive presence in sewers and treatment plants. Widely used in the chemical industry to produce inorganic sulfurs and sulfuric acid , it is also used in metallurgy to remove impurities from certain minerals.

Health Effects of Hydrogen Sulfide

Colorless , hydrogen sulfide (H2S) is a gas characterized by its rotten egg odor. It is a highly toxic gas by inhalation (R26) and responsible for cellular hypoxia. Exposure to low concentrations slightly affects the ocular mucous membranes (swelling around the eyes) and respiratory tract (burning in the lungs). It is also extremely flammable (R12), especially in contact with oxidants with explosive limits between 4 and 46% volume.

H2S (Hydrogen Sulfide) gas detection

Although hydrogen sulfide is an odorous gas (rotten egg smell), only an H2S gas detector can accurately measure the concentrations of this extremely toxic gas, so we will move towards portable hydrogen sulfide detection (portable 4 gas detector) or fixed in ppm.

For the calibration and gas testing of your fixed or portable gas detectors, hydrogen sulfide standard gas cylinders are available.

Hydrogen sulfide (H2S) respiratory protection

For effective respiratory protection against hydrogen sulfide, we will opt for a half mask or a full mask for short-term interventions or for a more comfortable assisted ventilation device with type B anti-gas filters.
