Silane – SiH4

Here silicon tetrahydride ( SiH4 ) or  silane You can find basic information about: properties, health effects, detection devices and systems – silane gas detector  – and appropriate respiratory protective equipment (self-contained breathing apparatus and supplied-air respirator).

Silane properties (SiH4)

silicon tetrahydride ( SiH4 ) – most commonly silane – known as – is an active gas used primarily to deposit silicon substrates. This process is carried out in the glass industry by pyrolysis: the oxygen-free thermal decomposition of organic materials. It is also used to produce amorphous silicon for photocopiers or solar cells.

Health effects of silane

At ambient temperature silane ( SiH4 ) is a colorless gas with a distinctive odor. Because it is heavier than air, it can displace oxygen in poorly ventilated areas and create suffocating environments. The biggest danger of sila is that it is explosive. Indeed, being extremely flammable, it can spontaneously ignite on contact with air. When heated, it produces hydrogenated silicone, which increases the risk of explosion.

Silane can be inhaled and swallowed. When released, this gas can quickly reach dangerous concentration levels in the air. When inhaled, silane causes headache, nausea, cough, and sore throat. Rapid evaporation of the liquid can cause freezing.

Silane gas detector – SiH4

Although SiH4 can be detected by smell, concentrations of this asphyxiating gas can only be detected in one silane gas detector can measure accurately. Therefore fixed or portable silane gas detection It is recommended to use devices or systems .

Silane calibration gas cylinders are available for calibration and gas testing of your fixed or portable gas detectors.

SiH4 respiratory protection – Silane

Since silane is an asphyxiating gas and poses a high risk of suffocation, open-circuit use should not be used in long-term applications. self-contained breathing apparatus or air supply respirator It is recommended to use .
