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).
