Hydrogen Sulfide – H2S

At work hydrogen sulfide  or sulfur hydrogen ( H2S ) basic information about: properties, health effects, detection devices and systems – hydrogen sulfide detector – and to organic vapors Suitable respiratory protective equipment against – H2S respirator: B with gas filter gas mask or PAPR .

Hydrogen sulfide (H2S) properties

Hydrogen sulfide (H2S) – also known as sulfurous hydrogen – occurs naturally on Earth. This gas is depleted during the decomposition of organic and bacterial material – which explains its large presence in sewers and wastewater treatment plants. It is widely used in the chemical industry to produce inorganic sulfurs and sulfuric acid. H2S can also be found in the steel industry to remove dirt from metals.

Health effects of hydrogen sulfide

Hydrogen sulfide ( H2S), a strong smell of rotten eggs It is a colorless gas with . When this gas is inhaled It is very toxic (R26) and causes cellular hypoxia. Exposure to low concentrations affects the eyes (swelling) and respiratory system (lung burns). Moreover is extremely flammable (R12), especially in contact with oxidizers with explosive limits between 4% and 46% by volume.

Hydrogen sulfide detector – H2S

Even if H2S and organic vapors have a rotten egg odor, there is only one hydrogen sulfide detector can accurately measure concentrations of this highly toxic gas. portable device that performs ppm measurements ( portable 4 gas portable ) or fixed hydrogen sulfide detection It is recommended to use equipment.
Hydrogen sulfide calibration gas cylinders are available for calibration and gas testing of your fixed or portable gas detectors.

H2S respirator – Hydrogen sulfide

To obtain appropriate respiratory protection against hydrogen sulphide, for short interventions The use of an H2S respirator such as a full face mask is recommended. A complete fit for comfort and safety for longer exposure Use PAPR (powered air purifying respirator). Both devices With type B filter cartridges must be equipped . At concentrations exceeding 60 times the OEL, a self-contained breathing apparatus (SCBA or airway system) is mandatory.
