Section 6. Accidental Release Measures
Small SpillUse appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according to local and regional authority
requirements.
Large SpillUse a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water
on the contaminated surface and allow to evacuate through the sanitary system.

Section 7. Handling and Storage
PrecautionsKeep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the
residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe dust.
Avoid contact with eyes Wear suitable protective clothing If ingested, seek medical advice immediately and show
the container or the label. Keep away from incompatibles such as oxidizing agents.
StorageKeep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly
closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat
and away from strong oxidizing agents.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
