Silane - SiH4
Silane - SiH4
This page brings together the main information on the " silicicon tetrahydride (SIH4) or silane as its physical characteristics, its effects on health, the means to detect it (SIH4 gas detector) as well as adapted respiratory protection equipment (insulating respiratory equipment or air supply system).
Key features of silane (SiH4)
The " silicon tetrahydride (SIH4) better known as a name silane is an active gas, mainly used for silicon-based layer deposition. In the glass industry, this process is carried out by pyrolysis (thermal decomposition of organic matter in the absence of oxygen). It is also used in the manufacture of amorphous silicon for photocopier drums or solar cells.
Effects of silane on health
At room temperature, the Silane (SIH4) is a colorless gas with a characteristic odor. Heavier than air, it can create asphyxiating environments by replacing the oxygen present in the low ventilated areas. The main danger, however, remains its explosibility, of an extremely flammable nature, it can ignite spontaneously in contact with air. While heating, it produces hydrogen silicon, increasing the risk of explosion.
The silane can be absorbed by the body by inhalation. A dangerous concentration of this gas in the air is very quickly reached if it escapes from its container. If it is inhaled, the silane causes headaches, nausea, cough and sore throat. Fast evaporation of the liquid can cause frostbite.
SIH4 gas detection (silane)
Although odor discernable, only a SiH4 gas detector can accurately measure the concentrations of this asphyxiating gas, so we will move towards a fixed or portable silane detection.
For the calibration and gas tests of your fixed or laptop gas detectors, silane gas bottle are available.
Silane Respiratory Protection (SIH4)
Silane is an asphyxious gas with significant risks of suffocation, we will move towards a Respiratory apparatus isolateOpen circuit t (Arico) or an air supply system for long-term interventions.
