No food or smoking in working area. Wash hands and face before eating. At the end of the day, clean the work shoes and shower; clothing should be completely changed. All work clothes should be laundered before being worn again.
Arsine may be accidentally formed by the reaction of arsenic impurities in commercial acids stored in metal tanks, so that a test should be made for arsine before entry is made into such vessels.
Evacuation: If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location, and weather conditions.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ...
