Health Hazards Information - Recommended Personal Protective Equipment: Selfcontained breathing
apparatus for high vapor concentrations; goggles or face shield; rubber gloves; Symptoms Following
Exposure: Inhalation of concentrated vapor may cause irritation of respiratory tract, depression, and
pulmonary edema. Liquid can cause irritation of eyes and (on prolonged contact) irritation and cracking
of skin. Ingestion causes irritation of mouth and stomach. Aspiration causes severe lung irritation,
rapidly developing pulmonary edema, and central nervous system excitement, followed by depression;
General Treamzent for Exposure: INHALATION: remove victim from exposure; apply artificial
respiration if breathing has stopped; call physician if needed. EYES: irrigate with copious quantities
of water for 15 min. SKIN: flush with water; wash with soap and water. INGESTION: do NOT induce
vomiting; call a physician. ASPIRATION: enforce bed rest; give oxygen; get medical attention;
Toxicity by Inhalation (Threshold Limit Value): 440 ppm; Short-Tern Inhalation Limits: 500 ppm for
30 min.; Toxicity by Ingestion: Data not available; Late Toxicity: Data not available; Vapor (Gas)
