Health Hazards Information - Recommended Personal Protective Equipment: Goggles or face mask;
rubber suit, apron, sleeves, andor gloves; rubber or leather safety shoes; air-line mask, positive-
pressure hose mask, self-contaminated breathiig apparatus, or industrial canister-type gas mask;
Symptoms Following Exposure: Inhalation causes irritation of nose and throat, followed by violent
sneezing, burning sensation in throat, coughing, constriction of larynx and difficulty in breathing,
pulmonary congestion, edema of the lung, and conjunctivitis. Contact with liquid burn eyes and skin.
(Severe exposure may cause blindness.) Vapors may cause dermatitis. Ingestion causes burns of the
mouth, throat, and esophagus; General Treatment for Exposure: Get medical attention for anyone
overcome or injured by exposure to this compound. INHALATION: remove victim to fresh air at once;
apply artificial respiration if breathing has stopped; administer oxygen. EYES: flush with water for at
least 15 min. SKIN: flush with water; if skin is burned do not use ointments or cover for 24 hours.
INGESTION: do NOT induce vomiting; give large amount of water; Toxicity by Inhalation (Threshold
Limit Value): 10 ppm; Short-Tern Inhalation Limits: Data not available; Toxicity by Ingestion: Grade
2, LD,, 0.5 to 5 glkg; Late Toxicity: Data not available; Vapor (Gas) Im’tant Characteristics: Vapors
are moderately irritating such that personnel will not usually tolerate moderate or high concentrations;
Liquid or Solid Zn-itant Characteristics: Causes smarting of the skin and first-degree burns on short
exposure; may cause secondary burns on long exposure; Odor Threshold: 0.021 ppm.
Fire Hazards - Flash Point : Not pertinent (flammable liquefied compressed gas); Flammable Limits
