Main Routes of Exposure: Inhalation.
- Inhalation: VERY TOXIC, can cause death. Can cause severe irritation of the nose and throat. At high concentrations: can cause life-threatening accumulation of fluid in the lungs (pulmonary edema). Symptoms may include coughing, shortness of breath, difficult breathing and tightness in the chest. A single exposure to a high concentration can cause a long-lasting condition like asthma. If this occurs, many things like other chemicals or cold temperatures can easily irritate the airways. Symptoms may include shortness of breath, tightness in the chest and wheezing. {Reactive Airways Dysfunction Syndrome (RADS)}.
- Skin Contact: CORROSIVE. The gas irritates or burns the skin. Permanent scarring can result. Direct contact with the liquefied gas can chill or freeze the skin (frostbite). Symptoms of mild frostbite include numbness, prickling and itching. Symptoms of more severe frostbite include a burning sensation and stiffness. The skin may become waxy white or yellow. Blistering, tissue death and infection may develop in severe cases.
- Eye Contact: CORROSIVE. The gas irritates or burns the eyes. Permanent damage including blindness can result. Direct contact with the liquefied gas can freeze the eye. Permanent eye damage or blindness can result.
- Ingestion: Not a relevant route of exposure (gas).
- Effects of Long-Term (Chronic) Exposure: May harm the respiratory system. Can irritate and inflame the airways.
- Carcinogenicity: Not known to cause cancer.
International Agency for Research on Cancer (IARC): Group 3 - Not classifiable as to its carcinogenicity to humans.
American Conference for Governmental Industrial Hygienists (ACGIH): A4 - Not classifiable as a human carcinogen.
- Teratogenicity / Embryotoxicity: Not known to harm the unborn child.
- Reproductive Toxicity: Not known to be a reproductive hazard.
- Mutagenicity: Suspect mutagen. May cause genetic damage based on animal information.
