Properties of hydrogen selenide (H2Se)

Hydrogen selenide ( H2Se ) – selenium hydride Also known as – is often used in the synthesis of selenium compounds. It can also be found in many industrial applications such as electronics (component manufacturing), steel industry (alloy preparation), glass or paint industry (pigmentation), rubber production (vulcanization) or copper refining.

Health effects of hydrogen selenide

Hydrogen selenide ( H2Se) , eyes , digestion And respiratory systems It is an inorganic compound that can irritate . This prompts at 0.05 ppm with an adjusted TWA (time weighted average) value most toxic It is a selenium compound. Even at very low concentrations, this compound has a very unpleasant horseradish-like odor that turns into a rotten egg smell at higher concentrations.

H2Se gas detector – Hydrogen selenium

Although H2Se can be detected by its very offensive odor, it is only a hydrogen selenide gas detector can accurately measure vapor concentrations of this highly toxic compound. Portable or stationary monitors concentrations in ppm or ppb (SPM FLEX) hydrogen selenide detection It is recommended to use devices.

Hydrogen sulfide respiratory protection – H2Se

Since hydrogen selenide is very irritating, a full face mask or a full face mask should be used for short interventions. B Equipped with a type filter, it is much more comfortable. PAPR It is recommended to install . For higher concentration levels exceeding 60 times the OEL, a self-contained breathing apparatus (SCBA) is mandatory.
