However, avoid open flames and high temperatures. Decomposition products may include hydrofluoric and hydrochloric acids, chlorine, fluorine, possible phosgene and carbonyl halids, carbon dioxide, and carbon monoxide.

Cylinders may vent or rupture in fire conditions, leading to decomposition. Use water spray to cool cylinders to prevent bursting or venting under fire conditions.
