pertinent; Heat of Combustion: Not pertinent; Heat of Decomposition: Not pertinent.
Health Hazards Information -Recommended Personul Protective Equipment: Dust mask; goggles or
face shield; protective gloves; Symptom Following Exposure: Inhalation causes irritation of nose and
throat. Ingestion causes severe circulatory collapse and chronic nephritis. Contact with eyes causes
irritation. Contact with skin may cause dermatitis and ulcers; General Treatment for Exposure:
INHALATION: remove to fresh air. INGESTION: give large amounts of water; induce vomiting.
EYES: flush with water for at least 15 min. SKIN: treat local injuries like acid burns; scrub with dilute
(2 %) sodium hyposulfite solution; Toxicity by Inhalation (Threshold Limit Value): 0.1 mg/m3; Short-
Tern Exposure Limits: Data not available; Toxicity by Ingestion: Grade 3: LD,, 50 - 50 mglkg; Late
Toxicity: Lung cancer may develop; Vapor (Gas) Irritant Characteristics: Data not available; Liquid
or Solid Irritant Characteristics: Data not available; Odor Threshold Data not available.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (%): Not flammable; Fire
