irritation of eyes and throat and can cause eye and lung injury. Vapors cannot be tolerated even at low
concentrations; Liquid or Solid Irritant Characteristics: Severe skin irritant. Causes second- and third-
degree burns on short contact and is very injurious to the eyes; Odor Threshold: No data. Fire Hazards
- Flash Point: Not flammable, but may cause fire on contact with combustibles; Flammable Limits in
Air (96): Not flammable; Fire Extingw'shing Agents: Dry chemical or carbon dioxide; Fire
Extinguishing Agents Not To Be Used Do not apply water on adjacent fires unless SCBA is used to
protect against toxic vapors; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire:
Vapors are extremely irritating to the eyes and mucous membranes. This product may increase the
intensity of fires; Ignition Temperature: Not pertinent; Electrical Hazard Not pertinent; Burning Rate:
Not pertinent.
