Nitrogen Tetroxide Exposure

Dinitrogen Tetroxide


Presentation

  • The present report is the committee's 18th interim report.[books.google.com]
  • This readable text presents the findings from the life science experiments conducted during and after space missions.[books.google.com]
  • Such compounds must be prepared in anhydrous conditions, since the nitrate ion is a much weaker ligand than water, and if water is present the simple hydrated nitrate will form.[en.wikipedia.org]
  • The nitrates present in silage crops are converted to nitrites through the fermentation process; they, in turn, react with the organic acids in the silage to form nitrous acid (HNO 3 ).[www1.agric.gov.ab.ca]
  • Vapor 90 90 90 420 Nitrogen tetroxide ( 95%, liquid, 21 C) 10544-72-6 Liquid 450 Special Warnings from DuPont Serged and bound seams are degraded by some hazardous liquid chemicals, such as strong acids, and should not be worn when these chemicals are present[cameochemicals.noaa.gov]
Weakness
  • The N-N distance corresponds to a weak bond, since it is significantly longer than the average N-N single bond length of 1.45 Å. [4] Unlike NO 2, N 2 O 4 is diamagnetic since it has no unpaired electrons. [5] The liquid is also colorless but can appear[en.wikipedia.org]
  • At 150 C, NO 2 decomposes withrelease of oxygen via an endothermic process (ΔH 114 kJ/mol): 2 NO 2 2 NO O 2 As suggested by the weakness of the N-O bond, 2 NO 2 is a good oxidizer and will sustain the combustion,sometimes explosively, with many compounds[jjstech.com]
  • After symptom-free period of 5-72 hours, pulmonary edema gradually develops, causing fatigue, restlessness, coughing, difficulty in breathing, frothy expectoration, mental confusion, lethargy, bluish skin, and weak, rapid pulse.[cameochemicals.noaa.gov]
Swelling
  • Exposure at high concentrations could cause asphyxiation due to swelling in the throat. Inhalation of the gas or vapour may cause lung oedema. See Notes. Exposure far above the OEL could cause death. The effects may be delayed.[inchem.org]
  • DuPont KLX-16001 exhibits lower volume swell, lower weight gain, and improved physical properties versus 1045, after long- term exposure to nitrogen tetroxide at 35 C.[gallagherseals.com]
  • Pulmonary edema involves fluid accumulation and swelling in the lungs that may be fatal or may lead to lasting respiratory problems.[www1.agric.gov.ab.ca]
Surgical Procedure
  • N 5002385 8709318 8711017 3294857497&rt r3 Electronics From customer service to airplanes to surgical procedures, the world continues to become more automated. Software and electronics are at the forefront of the revolution.[solutions.3m.com]
Nausea
  • Nitrogen dioxide exposure in low doses can cause irritation of the eyes and throat, headache, nausea, and gradual loss of strength. High doses of NO2 can cause pulmonary edema (water in the lungs) and death.[indsci.com]
  • […] using diesel powered machinery, garages, chemical plants Effects of Various NO 2 Levels Nitric Dioxide Level in PPM Resulting Conditions on Humans .2-1 Permissible Exposure Limit (OSHA) 1 Headache, dizziness, unsteadiness 5-10 Feeling of suffocation, nausea[jjstech.com]
  • (USCG, 1999) Health Hazard Very concentrated fumes produce coughing, choking, headache, nausea, pain in chest and abdomen; otherwise, few symtoms appear at time of exposure.[cameochemicals.noaa.gov]
Vomiting
  • After the water is swallowed, try to get the person to vomit by having him touch the back of his throat with his finger. Do not make an unconscious person vomit. Get medical attention immediately. ‏[books.google.com]
Choking
  • (USCG, 1999) Health Hazard Very concentrated fumes produce coughing, choking, headache, nausea, pain in chest and abdomen; otherwise, few symtoms appear at time of exposure.[cameochemicals.noaa.gov]
Vomiting
  • After the water is swallowed, try to get the person to vomit by having him touch the back of his throat with his finger. Do not make an unconscious person vomit. Get medical attention immediately. ‏[books.google.com]
Irritability
  • BACKGROUND: Reactive airways dysfunction syndrome (RADS) is characterized by persistent bronchial hyperreactivity and asthmatic symptoms in a previously healthy individual after a single intense exposure to an irritant fume, vapor, or gas.[ncbi.nlm.nih.gov]
  • 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[indsci.com]
  • Immediately leave the area and get into the fresh air if any nose or throat irritation or shortness of breath is experienced. Should the irritation or shortness of breath continue, seek medical attention promptly. Reference Pratt, D. S. 1993.[www1.agric.gov.ab.ca]
  • In 1975, three Apollo Soyuz astronauts were hospitalized for five days and treated for lung irritation after nitrogen tetroxide leaked from the steering jets into the cabin during reentry.[pbs.org]

Treatment

  • During that time, investigations have been conducted on both humans and animal models to study the bone demineralization and muscle deconditioning, space motion sickness, the causes and possible treatment of postflight orthostatic intolerance, the changes[books.google.com]
  • Other sources of nitrogen dioxide include petroleum and metal refining, electricity generation from coal-fired power stations, other manufacturing industries, and wastewater treatment plants.[indsci.com]

Epidemiology

  • There is limited evidence from epidemiological studies that individuals with asthma show steeper concentration-response relationships.[greenfacts.org]

Prevention

  • Measurement of C-reactive protein for the targeting of statin therapy in the primary prevention of acute coronary events. ‏ الصفحة 254 - At constant temperature, the volume of a gas is inversely proportional to the pressure upon it. ‏[books.google.com]
  • Close the feed room door to the barn to prevent contaminating the barn areas with nitrogen dioxide gas. 11. Post "DANGER - DEADLY SILO GAS" signs around the base of the silo to warn visitors, family members and workers to stay away. 12.[www1.agric.gov.ab.ca]
  • Prevent entry into waterways, sewers, basements or confined areas. Isolate area until gas has dispersed. Ventilate the area.[cameochemicals.noaa.gov]
