Health Hazards Information - Recommended Personal Protective Equipment: Self-contained breathing
apparatus, safety goggles; Symptoms Following Enposure: High vapor concentrations produce eye and
respiratory tract irritation, dizziness, depression. Liquid irritates and may blister skin; can cause
corneal injury to eye; General Treatment for Exposure: INHALATION: remove to fresh air and start
artificial respiration. INGESTION: do NOT induce vomiting; call a doctor. EYES AND SKIN: flush
with water for at least 15 min. Wash skin with soap and water; Toxicity by Inhalation (Threshold Limit
Value): Data not available; Short-Term Exposure Limits: Data not available; Toxicity by Ingestion:
Grade 2; oral rat LD,, 1.2 glkg; Late Toxicity: Data not available; Vapor (Gas) Im’tant Characteristics:
Vapors cause a slight smarting of the eyes and respiratory system if present in high concentrations. The
effect is temporary; Liquid or Solid Irritant Characteristics: Minimum hazard. If spilled on clothing
and allowed to remain, may cause smarting and reddening of the skin; Odor Threshold Data not
available.
