-6,790, -284; Heat of Decomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Protective clothing; eye
protection; Symptoms Following Exposure: Vapors cause irritation of eyes and respiratory tract. Liquid
irritates eyes and skin, may cause dermatitis; General Treatment for Exposure: SKIN OR EYES: flush
immediately with water for 15 min.; call a physician; Toxicity by Inhalation (Threshold Limit Value):
Data not available; Short-Term Inhalation Limits: Data not available; Toxicity by Ingestion: Data not
available; Late Toxicity: Repeated exposure can cause anemia and damage kidney and liver; 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: Causes
smarting of the skin and first-degree burns on short exposure; may cause secondary burns on long
exposure; Odor Threshold 0.0041 mg/m3.

Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Tmport: Stable; Neutralizing Agents for Aciak and Caustics: Flush with
water; Polymerizafion: Not pertinent; Inhibitor of Polymerizm'on: Not pertinent.

Health Hazards Information -Recommended Personul Protective Equipment: Self-contained breathing
apparatus; impervious gloves; chemical safety goggles; impervious apron and boots; Symptoms
Following Exposure: Inhalation of vapor irritates respiratory tract; high concentrations may cause
disturbance of central nervous system. Ingestion causes burns of mouth and stomach. Cause contact
with liquid causes burns of eyes and skin; General Treatment for Exposure: INHALATION: remove
victim to uncontaminated atmosphere; get medical attention. INGESTION: give large amom of water;
do NOT induce vomiting; get medical attention if large amount was swallowed. EYES: flush with water
for 15 min. and get medical attention. SKIN: flush with water; wash with soap and water; Toxicity by
Inhalation (Threshold Limit Value): Data not available; Short-Term Inhalation Limits: Data not
available; Toxicity by Ingestion: Grade 4; oral LD,, = 32 mg/kg (rat): Lute Taxicity: Data not
available; Vapor (Gas) Im'tant Characteristics: Data not available; Liquid or Solid Im'tant
Characteristics: Data not available; Odor Threshold: Data not available.
Fire Hazards - Flash Point (deg. F): 99 OC; Flammable Limits in Air ($6): 1.6 - 2.3; Fire
Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide; Fire Extinguishing Agents Not
To Be Used: Water may be ineffective; Special Hazarak of Combustion Products: Toxic oxides of
nitrogen may form in fires; Behavior in Fire: Vapor is heavier than air and may travel to a source of
ignition and flash back; Ignition Temperature : No data; Electrical Hazard: No data; Burning Rate: No
data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
