Trichlorosilane (HCl3Si) is a colorless fuming liquid with a pungent odor. The chemical's vapors and liquids cause burns. It is more dense than water and its vapors are heavier than air. Because it is flammable, we recommend a safe chemical storage building that meets specific regulations for storing Trichlorosilane.
