tract and cause nausea, vomiting, dizziness and loss of consciousness. Liquid irritates eyes and may
irritate skin; General Treatment for Eqvosure: INHALATION: remove from exposure; if breathing is
irregular or has stopped, start resuscitation and give oxygen; call a doctor. EYES: flush with water for
at least 15 minutes; Toxicity by Inhalation (Threshold Limit Value): 150 ppm; Short-Tern Inhalation

Vapor (Gas) Irritant Characteristics: Vapors causes a slight smarting of the eyes or respiratory system
if present in high concentrations. 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.
