What is Ammonia?
Ammonia is a colorless gas, with a pungent odor. It is widely used as a refrigerant and for the manufacture of products such as pesticides, fertilizer, plastic and other chemicals. Exposure to ammonia in small amounts can cause irritation to the eyes, nose and throat. At higher levels, ammonia may turn fatal due to throat swelling or chemical burns to the lungs. Ammonia is also highly corrosive. With an increased use of ammonia in recent years as a refrigerant, it is important to ensure worker safety by providing proper safety identification.
