Health Hazards Information - Recommended Personal Protective Equipment: Full face mask fitted
with organic vapor canister for concentrations over 75 ppm; clean protective clothing; eye protection;
Symptoms Following Exposure: INHALATION irritation of upper respiratory tract; over-exposure may
cause depression and injury to liver and kidney. EYES: pain and mild irritation; General Treatmentfir
Exposure: INHALATION: if any ill effects develop, remove patient to fresh air and get medical
attention. If breathing stops, give artificial respiration. EYES: flush with plenty of water and get
medical attention if ill effects develop. SKIN AND INGESTION: likely no problems; Toxicity by
Inhalation (ThresholdLim't Value): 75 ppm; Short-Tern ExposureLimits: 50 ppm for 60 min.; Toxicity
by Ingestion: Grade 2; LD,, 0.5 to 5 g/kg; Late Toxicity: Data not available; Vapor (Gas) Irritant
Characteristics: Vapors cause moderate irritation such that 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 the skin; Odor
Threshold: 15 - 30 ppm.
