Hazard Information

General Description
A colorless liquid with an agreeable odor. Toxic by inhalation and by skin absorption. BENZYL BROMIDE(100-39-0) is slightly soluble in water and denser than water (density 1.44 g/cm3 (Aldrich)). A lachrymator. Corrosive to metals and tissue.
Reactivity Profile
BENZYL BROMIDE reacts with water, alcohols, common metals (except nickel and lead), bases, amines and oxidizing agents. . This material stored over activated 4A molecular sieve burst a bottle due to condensation-polymerization reaction with generation of HBr gas, [Chem. Eng. News, 1979, 57(12), 74].
Air & Water Reactions
Sensitive to exposure to light and moisture. Slightly soluble in water.
Hazard
Highly toxic. Corrosive to skin and tissue. A lachrymator.
Health Hazard
Inhalation causes irritation of nose and throat; severe exposure may cause pulmonary edema. Vapors cause severe eye irritation; liquid can burn eyes. Skin contact causes irritation. Ingestion causes irritation of mouth and stomach.
Potential Exposure
It is used as a chemical intermediate; in organic syntheses; as a foaming and frothing agent.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
Shipping
UN1737 Benzyl Bromide, Hazard class: 6.1; Labels: 6.1—Poisonous materials, 8—Corrosive material.
Incompatibilities
May form explosive mixture with air. Contact with water forms hydrogen bromide and benzyl alcohol. Incompatible with strong oxidizers, bases, magnesium. Attacks metals, except nickel and lead, in the presence of moisture.
Waste Disposal
Pour into vermiculite, sodium bicarbonate, or a sand-soda ash mixture and transfer to paper boxes, then to an open incinerator. Alternatively, mix Benzyl Bromide 417 with flammable solvent and spray into incinerator equipped with after burner and alkali scrubber.
