2.3 Other hazards

Inhalation: The toxicity of this gas mixture depends upon the amount of nitric oxide present. Generally the only symptoms occurring at the time of exposure are slight cough, fatigue, and nausea. Very concentrated fumes may cause coughing, choking, nausea, headache, abdominal pain and tightness, and burning in the chest. Severe symptoms may be delayed (possibly for several hours) and include cyanosis, increased difficulty in breathing (from hypoxia), irregular respiration, lassitude and eventual death due to pulmonary edema in untreated cases. Repeated exposure to nitric oxide may cause a permanent decrease in pulmonary function (Silo Filler's Disease) or chronic irritation of the respiratory tract with cough, headache, loss of appetite, dyspepsia, tooth corrosion and gradual loss of strength. Nitrogen acts as a simple asphyxiate. Accumulation of high concentrations can displace oxygen content in the air necessary to support life. Skin Contact: May cause irritation. Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color change to gray or white, and blistering. Eye Contact: May cause irritation. Contact with rapidly expanding gas near the point of release may cause frostbite. Ingestion: Not anticipated. Product is a gas at normal conditions. Colorless non-flammable gas. May cause skin, eye, and respiratory irritation. This product contains nitric oxide which is toxic at relatively low concentrations. Symptoms are dependent upon concentration of nitric oxide and duration of exposure and may be delayed. If respiratory, skin or eye irritation occurs when working with this product, inhalation exposure may have already occurred. Nitric oxide can cause chemical pneumonitis, retention of body fluid and swelling in the lungs (edema) or cyanosis. Prompt medical attention is mandatory in all cases of overexposure. Nitrogen acts as a simple asphyxiant by displacing oxygen necessary to support life. Contents under pressure. Use and store below 125 °F (52 °C).
