of Vaporization: 225, 125, 5.23; Heat of Combustion: (est.) -14,400, -8000, -335; Heat of
Decomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Organic canister or air
pack; rubber gloves; goggles; Symptoms Following Exposure: Headache, dizziness, nausea, irritation
to respiratory passages. Irritates eyes; General Treatment for Exposure: INHALATION: remove from
exposure immediately; call a physician; if breathing is irregular or has stopped, start resuscitation and
administer oxygen. EYE CONTACT: flush with water for at least 15 min.; Toxicity by Inhalation
(Threshold Limit Value) : Data not available; Short-Tern Inhalation Limits: Data not available; Toxicity
by Ingestion: Grade 1; LD,, 5 to 15 g/kg; Late Toxicity: None; Vapor (Gas) Im'tm Characteristics:
Vapors cause moderate irritation such that personnel will find high concentrations unpleasant. The
effect is temporary; Liquid or Solid Irritm Characteristics: Minimum hazard. If spilled on clothing
and allowed to remain, may cause smarting and reddening of skin; Odor Threshold Data not available.

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, and irritates eyes; General Treamrent for Exposure: INHALATION: remove victim to fresh air;
give artificial respiration if needed; call a doctor. SKIN: flush with water. EYES: flood with water for
at least 15 min.; consult a doctor; Toxicity by Inhalation (Threshold Limit Value): 25 ppm; Short-Tern
Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 2, LD,, 0.5 to 5 g/kg (rat); Late
Toxicity: None; 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 skin; Odor lhreshold Data not available.
