Nitric oxide - NO
This page provides information on nitric oxide (NO) – also called nitrogen oxide or nitrogen monoxide: characteristics, effects on health, detection tools - nitric oxide detector or NOX detector - and proper respiratory protective equipment (ABEK1NOCO20-P3 combined filter or a self-contained breathing apparatus).
Nitric oxide (NO) properties
Nitric oxide (NO) – also known as nitrogen oxide – is an anthropogenic gas released by contact between nitric acid and many compounds. It can be found in many industries like wood (sawdust), explosives (dynamite), metals (engraving) and in high heat welding applications. This gas – which is partially responsible for atmospheric pollution – is exhausted by diesel-powered engines; that's why it is present in underground parking garages..

Nitric oxide effects on health
Nitric oxide is a colorless gas featuring a sweet smell that can be pungent starting at 0.3 ppm. As it is slightly soluble into water, it reacts with water molecules to form nitric acid, which is very corrosive. In case of chronic exposure, this gas can have irreversible effects (poison gas); it is also very toxic by inhalation (R26) and might cause chemical burns (R34).
