SECTION 2: Hazards identification

EMERGENCY OVERVIEW Irritating or corrosive to exposed tissues. Inhalation of vapors may result in pulmonary edema and chemical pneumonitis. Slightly flammable.

Potential health effects

Exposure Limits Irritant Sensitization Yes No Teratogen Reproductive Hazard Mutagen No Yes Synergistic Effects None Reported Carcinogenicity -- NTP No IARC No OSHA No EYE EFFECTS: Mild concentrations of product will cause conjunctivitis. Contact with higher concentrations of product will cause swelling of the eyes and lesions with a possible loss of vision. SKIN EFFECTS: Mild concentrations of product will cause dermatitis or conjunctivitis. Contact with higher concentrations of product will cause caustic-like dermal burns and inflammation. Toxic level exposure may cause skin lesions resulting in early necrosis and scarring. INGESTION EFFECTS: Since product is a gas at room temperature, ingestion is unlikely. INHALATION EFFECTS: Corrosive and irritating to the upper respiratory system and all mucous type tissue. Depending on the concentration inhaled, it may cause burning sensations, coughing, wheezing, shortness of breath, headache, nausea, with eventual collapse. Inhalation of excessive amounts affects the upper airway (larynx and bronchi) by causing caustic-like burning resulting in edema and chemical pneumonitis. If it enters the deep lung, pulmonary edema will result. Pulmonary edema and chemical pneumonitis are potentially fatal conditions.
