Nitrogen dioxide - NO2
Carbon dioxide - CO2
This page brings together the main information on carbon dioxide or "carbonic gas" (CO2), its physical characteristics, its effects on health, the means of detecting it (CO2 gas detector) as well as the appropriate respiratory protection equipment (self-contained breathing apparatus or air-supplied systems).
Main characteristics of carbon dioxide (CO2)v
Nitrogen dioxide (NO2 ) is a gas considered responsible for air pollution, and is one of the main indicators of air quality monitoring agencies. It is produced by the internal combustion of diesel engines and is found in all areas where these vehicles are used (mining operations, garages, parking lots, etc.). Widely used in the chemical industry, it allows the synthesis of nitric acid (HNO3).
Health effects of nitrogen dioxide
Nitrogen dioxide is a yellowish-brown gas with a pungent odor from 0.2 ppm. Irritating to the eyes (R36) and respiratory tract (R37), it is an extremely toxic gas by inhalation (R26) and responsible for burns (R34). Non-flammable and non-explosive, nitrogen dioxide is a powerful oxidant, capable of activating combustions and its reactivity with many chemical compounds (chlorinated compounds, benzene) can cause explosive mixtures.
NO2 (Nitrogen Dioxide) Gas Detector
Although identifiable by its smell and color, only a NO2 gas detector can accurately measure the concentrations of this particularly toxic gas, so we will move towards fixed or portable nitrogen dioxide detection .
For the calibration and gas testing of your fixed or portable gas detectors, nitrogen dioxide standard gas cylinders are available.
NO2 (Nitrogen Dioxide) Respiratory Protection
Nitrogen dioxide is toxic and asphyxiating with significant risks of suffocation, so we will move towards an open-circuit self-contained breathing apparatus (ARICO) or an air-supplied system for long-term interventions.
