Health Hazards Information - Personal Protective Equipment: Impervious gloves; splash goggles;
self-contained breathing apparatus if exposed to vapors; coveralls. Symptoms Following Exposure:
Inhalation may cause irritation of the mucous membrane. Ingestion causes irritation of mouth and
stomach. Contact with liquid irritates eyes and skin. Treatment for Eicposure: INHALATION: remove
victim to fresh air; apply artificial respiration and oxygen if indicated. INGESTION induce vomiting;
call a physician. EYES: wash with copious quantities of water for 15 min.; call a physician. 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 2; oral LD,
= 4 g/kg (rabbit) Late Toxicity: Causes birth defects in experimental animals Vapor (Gas) Imkm
Characteristics: Data not available Liquid or Solid Irritant Characteristics: Data not available Odor
Threshold: Data not available.
Fire Hazards - Flash Point (deg. F): 85 OC; 80 CC; Flammable Limits in Air (%): 1.8 (LFL); Fire
Extinguishing Agents: Foam, dry chemical, carbon dioxide; Fire Extinguishing Agents Not To Be Used:
Water may be ineffective; Special Hazark of Combustion Products: Data not available; Behavior in
Fire: Sealed container may rupture explosively if hot. Heat can cause a violent polymerization reaction
with rapid release of energy. Vapors are heavier than air and can travel considerable distance to a
source of ignition and flash back; Ignition Temperature (deg. F): 740; Electrical Hazard: Data not
available; Burning Rate: 4.56 mmlmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymeriza?iun: If proper concentration of inhibitor is not present or when material is hot, a violent
polymerization reaction may occur; Inhibitor of Polymerization: Oxygen in the air inhibits
polymerization.
