Doesn’t silane like catching fire when it sees an oxygen molecule? The other day I heard about it being used as rocket fuel for lunar ISRU applications.
A rocket and a sandblaster at the same time.
This is no worse than before. All electronic grade silicon is already produced starting from silane or trichlorosilane, and both are about equally hazardous to handle. See this overview of producing purified silicon:
