Ammonia - NH3

This page presents information about ammonia (NH3) – also known as hydrogen nitride: characteristics, effects on health, detection tools & systems - ammonia detector - and proper respiratory protective equipment (gas mask or powered air purifying respirator with K gas filter).

Ammonia (NH3) properties

Ammonia (NH3) - or hydrogen nitride - is industrially synthetized from nitrogen (N) and hydrogen (H2) using a catalyst (Haber-Bosch process). This substance is a key element for producing fertilizers and is used in the cooling industry. When dissolved into water, ammonia is used to produce household products. it is also exploited in the textile industry and for many other applications.

Ammonia effects on health

Above all ammonia is toxic (even at low concentrations) and very irritating to the eyes and breathing tracts. It can be easily detectable through smell with its pungent and asphyxiating smell. This gas is also flammable and explosive between 15 and 28% volume. Explosive reactions can occur if ammonia meets other substances such as halogens, mercury, or acetaldehyde.
