First-aid measures
A 24-HOUR MEDICAL SURVEILLANCE PERIOD IS MANDATORY IN ALL CASES OF EXPOSURE TO METHYL
BROMIDE, EVEN IN THE ABSENCE OF ANY IMMEDIATE SIGNS OF POISONING.
Eye contact: Holding the eyelids apart, flush eyes promptly with copious flowing water for at least 20 minutes. Get medical attention immediately.
Skin contact: Wash skin thoroughly with mild soap and plenty of water for at least 15 minutes. Get medical attention immediately. All leather items should be discarded. Other contaminated clothing must either be discarded or thoroughly ventilated and washed before re-use.
Inhalation: In case of inhalation, remove person to fresh air. Keep him quiet and warm. Apply artificial respiration if necessary and get medical
attention immediately.
Ingestion: If swallowed, wash mouth thoroughly with plenty of water. Get medical attention immediately.
NOTE: Never give an unconscious person anything to drink.
Most important symptoms and effects, both acute and delayed
Ocular: Severe irritant. Contact with liquid or high concentrations of gas with the eyes may cause severe but usually reversible injury involving temporary blindness.
Dermal: Liquid splashed on clothing or leather or high gas concentrations held in contact with skin may cause skin burns with large blisters appearing after several hours. Less severe exposures may cause itching skin rash even after several days. May be absorbed through the skin in sufficient amount to cause systemic toxicity.
Inhalation: Acute poisoning from methyl bromide is characterized by marked irritation to the respiratory tract which may lead, in severe cases, to pulmonary edema. High concentrations may damage the liver, kidneys and central nervous system. Symptoms of poisoning include headache, dizziness, somnolence, vertigo, blurred vision, slurred speech, nausea and vomiting and possibly convulsions and coma.
ONSET OF TOXIC SYMPTOMS MAY BE DELAYED FROM 30 MINUTES TO SEVERAL DAYS.
Ingestion: Severe irritant to mucous membranes and toxic poison if ingested, although ingestion
is highly unlikely.
Fire-fighting measures
Extinguishing media - Carbon dioxide, dry chemicals, foam, water spray (fog).
Special hazards arising from the substance or mixture - Although it is considered practically nonflammable, methyl bromide can be ignited
with a high energy source of ignition. Containers may rupture violently if exposed to fire or excessive heat for sufficient time. In confined spaces such as buildings or sewers, there is a danger of vapour accumulation, which may result in explosion in the presence of an ignition source. Will decompose from ca. 400°C releasing poisonous and corrosive fumes of carbon monoxide and hydrogen bromide.
Advice for fire-fighters- Wear self-contained breathing apparatus in positive pressure mode and appropriate protective clothing. If possible stop material flow immediately. Do not extinguish burning gas unless flow can be shut off immediately. Use water spray, fog nozzle or CO2 to keep cylinder cool. If there is no risk, move cylinder away from fire.
Accidental release measures
Personal precautions, protective equipment and emergency procedures - Evacuate area and keep personnel upwind. Wear self-contained breathing apparatus in positive pressure mode.
Methods and materials for containment and cleaning up - If practicable, stop flow of vapour. Ventilate and/or allow to evaporate, keeping people away from the area until safe reentry levels are shown by halide detector.
Handling and storage
Precautions for safe handling - Avoid bodily contact. Use an appropriate monitoring instrument for methyl bromide in any area where it is being stored or handled. Move and transport containers with requisite care. Do not use hooks, rope sling, etc. to unload. Use hand or fork trucks to firmly cradle cylinders. Do not bump or drag them.
Conditions for safe storage, including any incompatibilities - Store containers upright, in a secure manner, either outdoors under ambient
conditions, or indoors in a well ventilated area, away from seeds, foods/feedstuffs and human and animal habitation. Post as a pesticide storage area. Test periodically for leaks by halide leak detector.
Specific end use(s) - Feedstock only.

Exposure controls / personal protection
Exposure controls
Ventilation requirements Ventilation must be sufficient to maintain atmospheric concentration below recommended exposure limit.
Mechanical ventilation is recommended. Use local exhaust at source of vapour.
Personal protective equipment
- Respiratory protection For escape - Gas mask with a new organic vapour canister. For any detectable concentration - Self-contained breathing apparatus or supplied-air respirator with a full face-piece.
- Hand protection DO NOT WEAR GLOVES when working with MBr because of the danger that liquid or concentrated vapour may be trapped inside them.
- Eye protection Splash-proof safety glasses. CONTACT LENSES SHOULD NOT BE WORN WHEN WORKING WITH THIS CHEMICAL.
- Skin and body protection No specially designed protective clothing is available.
Do not wear gloves, impervious boots, finger rings or adhesive bandages on hands when handling this material.
Stability and reactivity
Reactivity - Decomposes above 400°C
Chemical stability - Stable in sealed containers and under normal conditions
Possibility of hazardous reactions - Hazardous polymerisation will not occur
Conditions to avoid - Keep away from ignition sources. Avoid contamination by water.
Incompatible materials - Strong oxidizers, aluminum, tin, zinc and magnesium metals and their alloys, natural rubber and certain types of plastics.
Hazardous decomposition products - CO, HBr
Disposal considerations
The recommended method is incineration. If a suitable designated combustion chamber is not available, return MARKED containers to supplier.
Contact local and/or state environmental authorities to insure proper compliance. Observe all federal, state and local environmental regulations whendisposing of this material.
