SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, carbon dioxide or alcohol-resistant foam.
Specific hazards arising from the chemical
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from incompatible materials. See Chemical Dangers.

SECTION 10: Stability and reactivity
Reactivity
no data available
Chemical stability
no data available
Possibility of hazardous reactions
No data.Decomposes on heating above the melting point. This produces toxic gases. Reacts with strong oxidants, nitrites, inorganic chlorides, chlorites and perchlorates. This generates fire and explosion hazard.
Conditions to avoid

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
