Silanes
Silane is a colorless gas that reacts with air and can cause asphyxiation. The gas usually comes into contact with the air and causes combustion and emits a very thick white amorphous silica fume. Its main danger to health is that its spontaneously combusting flames can cause severe thermal burns, which can be fatal even if severe. If a flame or high temperature acts on a part of the silane cylinder, the cylinder will be before the safety valve is activated**. If the pressure is too high or too fast when the silane is released, this will cause a delay**. If the leaking silane does not spontaneously ignite, it is very dangerous. Emergency personnel must be equipped with personal protective equipment and firefighting equipment appropriate to the situation. Do not attempt to extinguish the fire until the gas supply is interrupted.

Silane gas is an indispensable material in the manufacture of solar cells because it is the most efficient way to attach silicon molecules to the surface of the cell. In environments above 400 °C, silane gas decomposes into gaseous silicon and hydrogen. After the hydrogen is burned, what is left is pure silicon. In addition, it can be said that silane gas is everywhere. In addition to the photovoltaic industry, there are many manufacturing plants that use silane gases, such as flat panel screens, semiconductors, and even coated glass manufacturers.
