4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air, rest. Refer for medical attention.
In case of skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap.
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
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. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aromatic hydrocarbons and related compounds/
5.Fire-fighting measures

Special Hazards of Combustion Products: Irritating hydrogen bromide gas may be formed. Behavior in Fire: Forms vapor that is a powerful tear gas. (USCG, 1999)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautions
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Personal protection: chemical protection suit including self-contained breathing apparatus.
6.3 Methods and materials for containment and cleaning up
Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Ventilate area of spill or leak. ... If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.
7.Handling and storage
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilities
Separated from strong oxidants, strong bases and food and feedstuffs. Dry. Well closed.In general, materials which are toxic as stored or which can decomposition into toxic components due to heat, moisture, acids, or acid fumes, should be stored in cool, well ventilated place, out of sun, away from area of high fire hazard and should be periodically inspected and monitored. Incompatible materials should be isolated.

Eye/face protection
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

12.3 Bioaccumulative potential
An estimated BCF of 39 was calculated in fish for benzyl bromide(SRC), using a log Kow of 2.92(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). However, bioconcentration is expected to be attenuated by hydrolysis(SRC), with a calucalted chemical hydrolysis half-life of 79 minutes(4).
12.4 Mobility in soil
The Koc of benzyl bromide is estimated as 340(SRC), using a log Kow of 2.92(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that benzyl bromide is expected to have moderate mobility in soil. However, adsorption on moist soil is expected to be attenuated by hydrolysis(SRC), with a calucalted chemical hydrolysis half-life of 79 minutes(4).
