Chlorine is greenish yellow gas with a characteristic pungent odor. Although not classified as an explosive gas, chlorine will react explosively or form an explosive compound when combined with substances like acetylene, ether, turpentine, ammonia, hydrogen, and fuel gas.

Chlorine derivatives are commonly used for their disinfectant properties. Chlorine is highly toxic. The toxins take their route through the lungs irritating the respiratory tract. High doses of chlorine gas can cause death quite rapidly.

Effects of Various CL2 Levels  

Chlorine Level in PPM               Resulting Conditions on Humans

.5                                           Permissible Exposure Level (OSHA, ACGIH)

3                                            Irritation of the mucous membranes, eyes, and respiratory tract.

3.5                                         Produces an easily detectable odor

15                                          Causes immediate irritation of the throat

30                                          Maximum exposure for 30 minute period

100-500                               Pain, tightness in the chest, and death results from prolonged exposure
