Health Hazards Information -Recommended Persona2 Protective Equipment Organic vapor canister;
goggles and face shield; rubber gloves; boots and apron; Symptoms Following Exposure: Irritates eyes
and skin. Potent sensitizer and lung irritant if inhaled. May produce bronhospasm (asthma),
pneumonitis, bronchitis, and pulmonary edema. Nocturnal cough and shortness of breath are common.
Repeated low-level exposure may produce chronic lung disease. Oral toxicity is low; General Treatment
for Exposure: INHALATION: remove victim to fresh air; administer artificial respiration and oxygen
if needed; call a doctor. EYES: flush with water; wipe off; with rubbing alcohol; wash with soap and
water; Toxicity by Inhalation (Threshold Limit Value): 0.02 ppm; Short-Tern Exposure Limits: 0.02
ppm for 5 min.; Toxicity by Ingestion: Grade 2, LD,,0.5 to 5 gkg; Late Taxicity: Data not available;
Vqor (Gas) Irritant Characteristics: Vapors is moderately irritating such that personnel will not
usually tolerate moderate or high vapor concentration; Liquid or Solid Irritant Characteristics: Fairly
Severe skin irritant; may cause pain and second-degree burns after a few minutes' contact; Odor
Threshold 0.4-2.14 ppm.
Fire Hazards - Flash Point (deg. F): 270 OC; Flammable Limits in Air (96): 0.9 - 9.5; Fire
Extinguishing Agents: Water, foam, dry chemical, or carbon dioxide; Fire Extinguishing Agents Not
To Be Used: Water or foam may cause frothing; Special Hazardr of Combustion Products: Irritating
vapors are generated upon heating; Behavior in Fire: Not pertinent; Ignition Temperature (deg. F): >
300; Electrical Hard: Not pertinent; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: A non violent reaction occurs forming carbon dioxide
gas and an organic base; Reactivity with Common Materials: No reactions; Stability During Tmport:
Stable; Neutralizing Agents forAcids and Caustics: Not pertinent; Polymerization: Slow polymerization
occurs at temperatures above 113 of. The reaction is not hazardous; Inhibitor of Polymerization: Not
pertinent.
