Another fun Silane fact for you - The auto-ignition temperature is right around room temperature / a bit lower, and pure silane burns with "invisible" colorless flames! I worked at a semiconductor equipment manufacturer, and the silane gas delivery systems had to have separate flame detectors (from the normal one's we used) in the gas boxes for cutting off the gas supply because of this risk. We also had special strobe lights in the building with a sign below them indicating "Silane Pad on Fire if flashing", to let us know the gas bottle out behind the building (gas was piped in) was likely burning, since you wouldn't know from looking out the door / window unless you got close enough to feel the heat! Luckily, I never experienced a silane fire, but for a point, I did design and implement the safety system for an experimental ion implant system, which used silane along with other nasty process gases containing arsenic, boron and other dopants. Cool job, but the stress of "make sure you get this right" was a lot higher than other software jobs I've had, haha!
