Major sources of NO2 are internal combustion engines (diesel engines), and thermal power stations. Other sources of nitrogen dioxide include petroleum and metal refining, electricity generation from coal-fired power stations, other manufacturing industries, and wastewater treatment plants. Regardless of industry or application, Industrial Scientific offers a wide range of nitrogen dioxide gas detection instruments including the Tango® TX1 and GasBadge® Pro single-gas detectors, the Ventis® Pro, Ventis® MX4, MX6 iBrid® multi-gas detectors, as well as the Radius® BZ1 Area Monitor. Talk to an Expert RELATED GAS DETECTORS - NITROGEN DIOXIDE Radius BZ1 Ventis Pro MX6 iBrid Ventis MX4 Tango TX1 GasBadge Pro NITROGEN DIOXIDE - NO2 Hazard: Flammable - Will not explode Classification: Health - Extremely toxic Oxidizing - Oxidizing agent Synonyms: Dinitrogen tetroxide, nitrogen peroxide nitrogen tetroxide, and NTO Exposure limits: (OSHA) PEL\TWA: 5 ppm (ACGIH) STEL: 5 ppm/ 15 min. (OSHA) IDLH: 50 ppm / 30 min. Industries: Mining using diesel powered machinery, garages, chemical plants Nitrogen dioxide is a yellow-brown gas with a characteristic pungent, acrid odor. Nitrogen dioxide is soluble in water at which time it reacts to form nitric acid. NO2 can be found in industries where the burning of diesel fuel takes place. The most toxic component in diesel emissions is nitrogen dioxide. Nitrogen dioxide exposure in low doses can irritate the eyes and throat, or cause a headache, nausea, and gradual loss of strength. High doses of NO2 can cause pulmonary edema (water in the lungs) and death. Effects of Various NO2 Levels Nitric Dioxide Level in PPM Resulting Conditions on Humans .2-1 Detectable by pungent, acrid odor. 1 Permissible Exposure Level (OSHA, ACGIH). 5-10 Irritation of the nose and throat. 20 Irritation of the eyes. 50 Maximum exposure for a 30 minute period. 100-200 Tightness in the chest, acute bronchitis, and death from prolonged exposure.
