stomach; General Treatment for Exposure: INHALATION: remove victim to fresh air; if breathing is
difficult, call a physician. EYES: immediately flush with water for 15 min.; get medical attention.
SKIN: wash promptly with soap and water. INGESTION: give large amount of water, and induce
vomiting; follow with gastric lavage and saline cathartics; get medical attention; Toxicity by Inhalation
(Threshold Limit Value) : 5 ppm; Short-Tern Inhulation Limits: 50 ppd30 min. ; Toxicity by Ingestion:
Grade 3; oral LD,, = 132 mg/kg (rat); Lute Toxicity: Data not available; Vapor (Gas) Irritant
Characterisfics: 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: 8 ppm.
Fire Hazards -Flash Point (deg. F): 167 OC, 149 CC; Flammabk Limits in Air (A): 1.8 - 16.3; Fire
