The atmosphere that surrounds us is made up of a huge number of gasses. One of them is chlorine gas which is greenish yellow in color and has a bitter odor. This gas is not explosive but when it combines with other substances like acetylene, ether, turpentine and many more, it makes an explosive compound. This gas in itself is inflammable and can be used as oxidizing agent but it is highly toxic in nature. The chlorine irritates the respiratory tract. This gas if taken in high dose can be the reason for death. It is generally used in disinfecting materials due to its disinfectant properties. Chlorine content in the air is considered harmful to the health of humans and with the rise in content of chlorine gas in air the intensity of harm increases proportionately.
