Hi there,
Well in the chip Fabs in OR. TSMC and Fujitsu they use a lot of it along with some shit that is pyrophoric if it hits oxygen (down in TX afew years ago) a couple techs Expired 
from it being in the tunnel between buildings after a leak. Gases are no joke when not monitored properly, I built a Hydrogen sensor that the company still uses today as our own canary in the UHP gas pad and cabinets…
some of that stuff btt you smell it your DOA!
