SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, carbon dioxide or alcohol-resistant foam.
Specific hazards arising from the chemical
Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 30°C explosive vapour/air mixtures may be formed.
Special protective actions for fire-fighters
Use carbon dioxide, special powder, dry sand. NO other agents. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
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
NO open flames, NO sparks and NO smoking. NO contact with halogens, halogenated compounds or oxidizing agents. Above 30°C use a closed system, ventilation and explosion-proof electrical equipment. 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
Fireproof. Separated from strong oxidants, halogens and food and feedstuffs. Cool. Dry. Keep under nitrogen atmosphere.
SECTION 8: Exposure controls/personal protection
Control parameters
TLV: 0.005 ppm as TWA; 0.015 ppm as STEL.MAK: 0.013 mg/m3, 0.005 ppm; peak limitation category: II(2)

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear face shield or eye protection in combination with breathing protection.
Protective gloves. Protective clothing.
Use ventilation, local exhaust or breathing protection.

SECTION 10: Stability and reactivity
Reactivity
no data available
Chemical stability
no data available
Possibility of hazardous reactions
The vapour is heavier than air.Decomposes at 150°C. This produces boron and flammable gas (hydrogen - see ICSC 0001). Decomposes on burning. This produces toxic fumes of boron oxides. Reacts with halogens, halogenated compounds, oils, greases and oxidants. This generates fire and explosion hazard. Impure material ignites spontaneously in air.

STOT-single exposure
The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system and liver. This may result in convulsions, acidosis and liver impairment. Exposure above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
STOT-repeated exposure
no data available
Aspiration hazard
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

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.
