Hazards
Silane is explosive when mixed with air (1 – 98% SiH4). Other lower silanes can also form explosive mixtures with air. The lighter liquid silanes are highly flammable, this risk increases with the length of the silicon chain.
Considerations for detection/risk control:
- Silane is slightly heavier than air (possibility of pooling at ground levels/pits)
- Disilane is heavier than air (possibility of pooling at ground levels/pits)
- Trisilane is heavier than air (possibility of pooling at ground levels/pits)
