Section 6: Accidental Release Measures
Use 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.
Use 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
Keep 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. If ingested, seek medical advice
immediately and show the container or the label. Keep away from incompatibles such as oxidizing agents.
Moisture sensitive. Keep container tightly closed. Keep container in a cool, well-ventilated area. Preferably freeze (Store
between -25°C (-13°F) and -30 C). Otherwise, keep refrigerated.
Section 8: Exposure Controls/Personal Protection
Use 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.
Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves (impervious).
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
