Ammonia Gas Detection

CAS Number: 7664-41-7
TWA: 25ppm
STEL: 35ppm

Properties

It is a colourless gas with a pungent suffocating odour, which smells like rotten eggs. Ammonia is characterised as a flammable although it is very difficult to ignite. When exposed to heat, an ammonia solution will decompose to form Ammonia gas and oxides of Nitrogen, (NOx).

Dangers

Ammonia will become extremely irritating as concentrations increase. Exposure to high concentrations of ammonia in air causes immediate burning of the nose, throat and respiratory tract, and could cause respiratory distress or failure. Inhalation of lower concentrations can cause coughing, and nose and throat irritation. Ammonia's odour provides adequate early warning of its presence, but ammonia also causes olfactory fatigue (where the human nose blanks out the smell although the gas remains present), reducing awareness of prolonged exposure at low concentrations.

Where is it found

Ammonia (NH3) naturally exists in humans and in the environment. It is produced naturally from decomposition of organic matter, including plants, animals and animal waste. Ammonia is one of the most commonly produced industrial chemicals. that can be found in a variety of common industrial environments such as fertiliser plants, poultry farms, food processing, refrigeration and chemical plants.
