Health Hazards Information - Recommended Personal Protective Equipment: All-service canister
mask; rubber gloves; chemical safety goggles andor shield; overalls or a neoprene apron; barrier
creams; Symptoms Following Exposure: Vapors cause moderate irritation of nose and throat. Liquid
cause severe burns of eyes and reddening and itching of skin. Prolonged contact with skin can cause
burns. Ingestion causes salivation, vomiting, respiratory difficulties, thready pulse, vertigo, headache,
loss of pupillary reflexes, hypothermia, cyanosis, mild convulsions; General Treamzent for Exposure:
INHALATION: remove victim to fresh air; if he is not breathing, give artificial respiration, preferably
mouth-to-mouth; if breathing is difficult, give oxygen; call a physician. EYES: flush immediately with
plenty of water for at least 15 min. And call a physician. SKIN: wipe with vegetable oil or margarine;
then wash with soap and water. INGESTION: have victim drink water or milk; do NOT induce
vomiting; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Tern Exposure
Limits: Data not available; Toxicity by Ingestion: Grade 2; LD,,0.5 to 5 glkg; Lute Toxicity: Repeated
exposures may cause cancer of skin; Vapor (Gas) Irritant Characteristics: Vapor cause moderate
irritation such that personnel will find high concentrations unpleasant. The effect is temporary: Liquid
or Solid Irritant Characteristics: Fairy severe skin irritant. May cause pain and second-degree burns
after a few minutes’ contact; Odor llreshold Data not available.
Fire Hazards - Flash Point (deg. F): > 160 CC; Flammable Limits in Air (56): Not pertinent; Fire
Extinguishing Agents: Dry chemical, carbon dioxide, or foam; Fire Extinguishing Agents Not To Be
Used Water may be ineffective; Special Hazards ofcombustion Products: Data not available; Behavior

-342.5 to -342.9; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Organic vapor canister
unit; rubber gloves; chemical safety goggles; face shield; coveralls andor rubber apron; rubber shoes
or boots; Symptoms Following Eqosure: Vapors cause irritation of eyes, nose, and throat. Contact with
skin or eyes causes severe burns. Chemical is rapidly absorbed through skin; General Treatment for
Exposure: Call a physician. INHALATION: remove to fresh air. INGESTION: have victim drink
water or milk; do not induce vomiting. SKIN OR EYES: flush immediately with plenty of water for
