Health Hazards Information - Recommended Personal Protective Equipment: Clean, body-covering
clothing and safety glasses with side shields. Respiratory protection: up to 50 ppm, none; 50 ppm to
296, H hr or less, full face mask and canister; greater than 2%, self-contained breathing apparatus;
Symptoms Following Exposure: Inhalation of vapors causes nausea, drunkenness, depression. Contact
of liquid with eyes may produce corneal injury. Prolonged contact with skin may cause a burn; General
Treament for Exposure: INHALATION: if victim is overcome, remove him to fresh air, keep him
quiet and warm, and get medical attention immediately; if breathing stops, give artificial respiration.
INGESTION induce vomiting; call a physician; treat the symptoms. EYES: flush immediately with
copious amounts of flowing water for 15 min. SKIN: remove clothing and wash skin thoroughly with
soap and water; wash contaminated clothing before reuse; Toxicity by Inhalation (Threshold Limit

Characteristics: Vapors cause moderate irritation such that personnel will find high concentrations
unpleasant. The effect is temporary; Liquid or Solid Irritant Characteristics: Causes smarting of the
skin and first-degree burns on short Exposure; may cause secondary burns on long Exposure; Odor
