Section 5. FIRE-FIGHTING MEASURES
Suitable extinguishing Dry chemical, foam, water spray, carbon dioxide.
media:
Specific hazards arising Explosion risk in case of fire. Fight fire remotely due to the risk of explosion.
from the chemical: Take care as it may decompose upon combustion or in high temperatures to
generate poisonous fume.
Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
method according to the surrounding situation is used. Uninvolved persons should
evacuate to a safe place. In case of fire in the surroundings: Keep containers cool by
spraying with water. Eliminate all ignition sources if safe to do so.
Special protective When extinguishing fire, be sure to wear personal protective equipment.
equipment for firefighters:
Section 6. ACCIDENTAL RELEASE MEASURES
Use personal protective equipment. Keep people away from and upwind of spill/leak.
Personal precautions,
protective equipment and Entry to non-involved personnel should be controlled around the leakage area by
emergency procedures: roping off, etc.
Environmental precautions: Prevent product from entering drains.
Methods and materials for Sweep dust to collect it into an airtight container, taking care not to disperse it.
containment and cleaning Adhered or collected material should be promptly disposed of, in accordance with
up: appropriate laws and regulations.
Prevention of secondary Remove all sources of ignition. Fire-extinguishing devices should be prepared in
hazards: case of a fire. Use spark-proof tools and explosion-proof equipment.
Section 7. HANDLING AND STORAGE
Precautions for safe handling
Technical measures: Handling is performed in a well ventilated place. Wear suitable protective equipment.
Be careful not to cause leakage, overflow, or dispersion. Steam should not be
generated unnecessarily. Keep away from heat/sparks/open flame/hot surfaces. -No
smoking. Take measures to prevent the build up of electrostatic charge. Use
explosion-proof equipment. Avoid shock and friction. Wash hands and face before
breaks and immediately after handling the product.
Use a local exhaust if dust or aerosol will be generated.
Advice on safe handling: Avoid contact with skin, eyes and clothing.
Conditions for safe storage, including any
incompatibilities
