Health Hazards Information - Recommended Personal Protective Equipment: Air-supplied mask;
goggles or face shield; rubber gloves; Symptoms Following Exposure: Vapors irritate nose, throat, and
lungs, causing coughing, choking and difficult breathing. Contact with eyes causes several burns.
Clothing wet with chemical causes burns; General Treatment for Exposure: INHALATION: remove
victim to fresh air; give artificial respiration in needed; call a doctor. INGESTION: induce vomiting
if patient is conscious. EYES: flush with water for at least 30 min.; call a doctor. SKIN: flush with
water for at least 30 min.; Toxicity by Inhalation (Threshold Limit Value): 25 ppm; Short-Term
Inhalation Limits: 100 ppm for 30 min.; Toxicity by Ingestion: Grade 3, LD,,50 to 500 mglkg (rat -
LD,460 mg/kg); Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapors cause
moderate irritation, such that personnel will find high concentration unpleasant. The effect is
temporary; Liquid or Solid Im’tant Characteristics: Causes smarting of the skin and first-degree bums
on short exposure; may cause secondary burns on long exposure; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 20 OC; Flammable Limits in Air (9%): 1.2 - 8.0; Fire
Extinguishing Agents: Carbon dioxide or dry chemicals for small fires; alcohol foam for large fires;
Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazara!s of Combustion
