Health Hazards Information - Recommended Personal Protective Equipment: Air pack or organic
canister mask; rubber gloves; goggles or face shield; Symptoms Following Exposure: Vapor irritates
eyes and nose; may cause anesthesia. Prolonged contact with liquid causes irritation and cracking of
skin; also irritates eyes; General Treatment for Exposure: INHALATION remove to fresh air; give
artificial respiration if needed; call a doctor. SKIN: flush with water. EYES: flush with water for at
least 15 min.; consult a doctor; Toxicity by Inhalation Freshold Lim't Value): 25 ppm; Short-Term
Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5 to 5 glkg (rat); Late

personnel will find high concentrations unpleasant. 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 skin; Odor Threshold Data not available.
