Signs and symptoms vary depending on how the person was exposed, the amount of chlorine (mass), and the length of time of the exposure. When chlorine gas comes into contact with moist tissues such as the eyes, throat, and lungs, an acid is produced that can damage these tissues. Most people will smell a noxious odor or feel irritation that indicates exposure to chlorine, but low-level exposure for a long time may affect their ability to sense the chemical.

Chlorine is also commonly used in a liquid form as sodium hypochlorite, such as household bleach.Chlorine can react explosively or form explosive compounds with many common substances such as acetylene, ether, turpentine, ammonia, fuel gas, hydrogen, and finely divided metals.

However, repeated exposure to chlorine reduces the ability to detect the odor. Chlorine gas can be recognized by its pungent, irritating odor, which is like the odor of bleach.When liquid chlorine is released, it quickly turns into a gas that stays close to the ground and spreads rapidly.Chlorine can also be pressurized and cooled to change into a liquid so it can be stored and transported. At room temperature, chlorine is a yellow-green gas under normal conditions and can be dissolved in water.

When chlorine gas comes into contact with moist tissues such as the eyes, throat, and lungs, an acid is produced that can damage these tissues.Chlorine is a chemical element commonly used in industry and found in some household products.
