Cl2
Chlorine
Chlorine (Cl2) is a greenish-yellow gas with a sharp, distinctive odour.
While it is not considered an explosive gas by itself, it can react explosively or create combustible compounds when mixed with substances such as acetylene, ether, turpentine, ammonia, hydrogen, and fuel gas.
Chlorine derivatives are widely used for their disinfectant qualities. However, chlorine is extremely toxic, irritating the respiratory system if it is inhaled, and exposure to high concentrations can be rapidly fatal.

Chlorine is toxic and if inhaled or drunk in concentrated quantities, can prove fatal. If chlorine gas is released into the air, people may be exposed through their skin, eyes or through inhalation. Chlorine is not combustible, however can react with most combustibles which poses a fire and explosion risk. It also reacts violently with organic compounds such as ammonia and hydrogen, causing potential fire and explosion.
Acute chlorine gas poisoning will cause difficulty breathing and a cough, as well as sneezing, nose and throat irritation. There may also be skin irritation or chemical burns, as well as eye irritation or conjunctivitis. A person with chlorine gas poisoning may also experience nausea, vomiting, or a headache.
If exposed, remove clothing, wash your entire body with large amounts of soap and water, and rinse eyes with plain water for 10 to 15 minutes.
