Health Hazards Information - Recommended Personal Protective Equipment: Rubber gloves; safety
goggles; dust mask; Symptoms Following Erposure: Inhalation causes inflammation of upper and lower
respiratory tract, including pneumonitis. Ingestion causes irritation of the mouth, nose, stomach and
intestines; vomiting, purging with bloody stools; slow pulse and low pressure; slow, shallow breathing;
coma and convulsions sometimes followed by death. Contact with eyes causes conjunctivitis. Contact
with skin causes dermatitis and rhinitis; General Treatment for Exposure: If any of the symptoms of
poisoning, even slight, are noticed, the affected individual should be removed from contact with the
chemical and placed under care of a physician. INGESTION: induce vomiting. EYES: flush with water
for at least 15 min. SKIN: wash well with soap and water; Toxicity by Inhalation (Threshold Limit
