6. Accidental release measures
Personal precautions,
protective equipment and
emergency procedures
Use only non-sparking tools. Keep unnecessary personnel away. Keep people away from and
upwind of spill/leak. Dust deposits should not be allowed to accumulate on surfaces, as these may
form an explosive mixture if they are released into the atmosphere in sufficient concentration.
Wear appropriate protective equipment and clothing during clean-up. 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
Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Take
precautionary measures against static discharge. Use only non-sparking tools. Avoid dispersal of
dust in the air (i.e., clearing dust surfaces with compressed air). Stop the flow of material, if this is
without risk.
Large Spills: Wet down with water and dike for later disposal. Shovel the material into waste
container. Following product recovery, flush area with water.
Small Spills: Sweep up or vacuum up spillage and collect in suitable container for disposal.
Never return spills to original containers for re-use. 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.
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. Minimize dust generation and accumulation. Avoid significant deposits of
material, especially on horizontal surfaces, which may become airborne and form combustible dust
clouds and may contribute to secondary explosions. Routine housekeeping should be instituted to
ensure that dusts do not accumulate on surfaces. Keep away from heat/sparks/open flames/hot
surfaces. - No smoking. Explosion-proof general and local exhaust ventilation. Avoid prolonged
exposure. Wear appropriate personal protective equipment. Avoid release to the environment. Do
not burn preserved wood. Do not use preserved wood as Mulch. Observe good industrial hygiene
practices.
Conditions for safe storage,
including any incompatibilities
Keep away from heat, spark, open flames and other sources of ignition. Store away from
incompatible materials (see Section 10 of the SDS).
