Nitrogen Dioxide – NO2

This page nitrogen dioxide ( NO2 ), suitable detection tools – nitrogen dioxide detector – and provides information on respiratory protective equipment (self-contained breathing apparatus and supplied-air respirator).

Nitrogen Dioxide (NO2) properties

Nitrogen dioxide ( NO2 ), is considered responsible for atmospheric pollution. As a result, this gas is an important indicator for air quality monitoring agencies. It is produced especially by the internal combustion of diesel engines and can be found in every area (mines, garages, parking lots…) where these vehicles are located. NO2 is also used in the chemical industry e.g. nitric acid (HNO3) synthesis It is widely used for .

Health effects of nitrogen dioxide

Nitrogen dioxide, from 0.2 ppm sharp It is a yellow-brown gas with an odor. This gas is irritating to the eyes (R36) and respiratory system (R37). Moreover very toxic when inhaled (R26) and may cause burns (R34). Nitrogen dioxide, which is flammable and non-explosive, can ignite combustion is a strong oxidizer . Reaction with many chemical compounds (chloride compounds, benzene) can produce explosive gas mixtures.

Nitrogen dioxide gas detector

Although NO2 gas can be detected by its color and odor, only one A nitrogen dioxide detector can accurately measure concentrations of this particularly toxic gas. Therefore fixed or portable nitrogen dioxide detection It is recommended to use equipment .
Nitrogen dioxide calibration gas cylinders are available for the calibration and gas testing of your fixed or portable gas detectors.

NO2 respiratory protection (nitrogen dioxide)

Nitrogen dioxide is a toxic and suffocating gas with significant suffocation risks. Open circuit for long term applications self-contained breathing apparatus (SCBA) or a respirator that provides air It is recommended to use .
