Ammonia PDF Print E-mail
Ammonium hydroxide is alkaline and is part of many cleaning agents (see Bathroom cleaners ). Cloudy ammonia (with soap) and household ammonia contain about 10 per cent ammonia and give off pungent vapours. Ammonia gas is occasionally used as a refrigerant.

Health effects
People with chronic respiratory problems should not use ammonia. The vapours of household ammonia are highly irritating to the eyes and nose. Contact with the solution should be avoided as far as possible. Splashes should be washed off with large amounts of water. If the solution is ingested, drink large amounts of water and/or dilute acids such as lemon or vinegar. Seek medical attention.

Ammonia should never be mixed with chlorine-based cleaners such as bleaches as when mixed they give off toxic chlorine gases.
Ammonia gas in high concentration attacks the lung membranes. The strong smell will give warning of very low concentrations. Seek fresh air immediately.

Environmental effects
Ammonia is not damaging to the environment and is quickly converted to neutral salts like ammonium sulphate, ammonium phosphate or ammonium carbonate.
