OXIDIZERS CHEMICAL HAZARDS & RISK MINIMIZATION

Chlorine is liquified by pressurizing the gas until its critical pressure is reached (critical pressure is the pressure at which the particular gas turns to a liquid). However, the primary concern with chlorine in a liquid spill is the toxicity of the vapor produced. Oxygen and fluorine, on the other hand, are liquified by the process of cooling.
