materials.
General fire hazards No unusual fire or explosion hazards noted.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective
equipment and emergency
procedures
Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wear
appropriate protective equipment and clothing during clean-up. Do not touch damaged containers
or spilled material unless wearing appropriate protective clothing. Ensure adequate ventilation.
Local authorities should be advised if significant spillages cannot be contained. For personal
protection, see section 8 of the SDS.
Methods and materials for
containment and cleaning up
Stop the flow of material, if this is without risk. Prevent product from entering drains. Following
product recovery, flush area with water. For waste disposal, see section 13 of the SDS.
Environmental precautions
Avoid release to the environment. Prevent further leakage or spillage if safe to do so. Avoid
discharge into drains, water courses or onto the ground. Inform appropriate managerial or
supervisory personnel of all environmental releases.
SECTION 7. HANDLING AND STORAGE
Precautions for safe handling
Obtain special instructions before use. Do not handle until all safety precautions have been read
and understood. Provide adequate ventilation. Avoid breathing dust/fume/gas/mist/vapors/spray.
Avoid contact with eyes, skin, and clothing. Avoid prolonged exposure. Should be handled in
closed systems, if possible. Wear appropriate personal protective equipment. Avoid release to the
environment. Observe good industrial hygiene practices.
Conditions for safe storage,
including any incompatibilities
Store locked up. Store in original tightly closed container. Store away from incompatible materials
(see Section 10 of the SDS).
