Health Hazards Information - Personal Protective Equipment: Self-contained breathing apparatus;
goggles or face shield; rubber gloves. Symptoms Following Exposure: Inhalation or ingestion causes
headache, increased pulse rate, decreased blood pressure, and unconsciousness. Contact with liquid
irritates eyes and skin; Treatment for Exposure: INHALATION: remove victim from exposure; if
breathing has stopped, give artificial respiration; call physician. EYES: flush with water, wash with
soap and water. INGESTION do not induce vomiting; call physician. Toxicity by Inhalation (Threshold

Ingestion: Data not available; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics:
Data not available; Liquid or Solid Im’tm Characteristics: Data not available; Odor Threshold: Data
not available.
Fire Hazards - Fhh Point (deg. F): -31 CC; Flammable Limits in Air (%): 3 - >SO; Fire
Extinguishing Agents: Water dry chemical, carbon dioxide, water, foam; Fire Extinguishing Agents Not
To Be Used: Not pertinent; Special Hazards of Combustion Products: Toxic oxides of nitrogen are
generated; Behavior in Fire: Vapors are heavier than air and may travel a considerable distance to a
source of ignition and flash back; can decompose violently above 194“ F; containers may explode in
a fire; Ignition Temperature (deg. F): 194; Electrical Hazard: Data not available; Burning Rate: 2.6
dmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No

Health Hazards Information - Personal Protective Equipment: Air pack or organic canister respirator;
rubber gloves; goggles; clothing to prevent body contact with liquid. Symptoms Following Exposure:
Vapors irritate eyes and nose. Ingestion or skin contact causes headache, nausea, vomiting, dizziness.
Treatment for Exposure: INHALATION: remove to fresh air and call a physician. SKIN OR EYES:
immediately flush with plenty of water; get medical care for eyes. Toxicity by Inhalation (Threshold
Limit Value): 50 ppm Short-Tern Inhalation Limits: Data not available Toxicity by Ingestion: Grade 2;
LD,,O.5 to 5 g/kg (rat) Late Toxicity: Data not available Vapor (Gas) Irritant Characteristics: Vapors
cause 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 the skin. Odor Threshold: Data not available.
