44 BENZYL BROMIDE

164, 91, 3.8; Heat of Combustion: -16,260; -9,040; -378; Heat of Decomposition: Not pertinent.
Health Hazards Information -Recommended Personal Protective Equipment: Self-contained bream
apparatus; goggles of face shield; rubber gloves; Symptoms Following Exposure: Inhalation of vapor
causes irritation of mucous membranes of the nose and throat, and lung irritation with respiratory
distress and cough. Headache, nausea, faintness and anxiety can occur. Exposure to vapor produces
eye irritation with lachrymation, conjunctivitis, and corneal edema resulting in halos around lights.
Direct local contact with liquid is known to produce severe and sometimes permanent eye damage and
skin burns. Vapors may also produce primary skin irritation and dermatitis; General Treatment for
Exposure: INHALATION: remove victim from exposure, if breathing is difficult, administer oxygen,
if breathing has stopped, begin artificial respiration. EYES or SKIN wash with copious amounts of
water for 15 min; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Tern
Exposure Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor l%reshold Data not available.
Fire Hazards - Flash Point (deg. F): 168 OC; Flammable Limits in Air (96): No data; Fire
Extinguishing Agents: Alcohol foam, dry chemical, carbon dioxide; Fire Extinguishing Agents Not To
Be Used Water may be ineffective; Special Hazards of Combustion Products: Toxic nitrogen oxides
form in fire situations; Behavior in Fire: No data; Ignition Temperature: No data; Electrical Hazard
No data; Burning Rate: 4.13 dmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: In
presence of moisture may severely corrode some metals. In liquid state this chemical will attack some
plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with
water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus; goggles; rubber gloves; protective clothing; Symptoms Following Exposure: Inhalation
causes irritation of nose and throat; severe exposure may cause pulmonary edema. Vapors cause severe
eyes irritation; liquid can burn eyes. Skin contact cause irritation of mouth and stomach; General
Treatment for Exposure: INHALATION: remove to fresh air. EYES: irrigate with copious amount of
water for 15 min. SKIN: flush with water. INGESTION: do NOT induce vomiting; give large amounts
of water; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Tern Exposure
Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: Data not available;
Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant Characteristics: Data
not available; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 174 CC; Flammable Limits in Air (96): Not pertinent; Fire
Extinguishing Agents: Water, dry chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To
Be Used: Not pertinent; Special Hazards of Combustion Products: Irritating and toxic hydrogen
bromide gas is formed; Behavior in Fire: Forms vapor that is powerful tear gas; Ignition Temperature:
No data; Electrical Hazard No data; Burning Rate: 2.6 mm/min.
Chemical Reactivity - Reactivity with Water: Reacts slowly generating hydrogen bromide
(hydrobromic acid); Reactivity with Common Materials: Decomposes rapidly in the presence of all
common metals except nickel and lead, liberating heat and hydrogen bromide; Stability During
Transport: Stable; Neutralizing Agents for Acids and Caustics: Rinse with sodium bicarbonate or lime
