5 6. Accidental Release Measures NB: Wear appropriate protective equipment/clothing including gloves before removing any spills. Small spill: 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. Large spill: 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. 7. Handling and Storage Precautions: Do not breathe dust. Keep away from incompatibles such as oxidizing agents, acids Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area. 8. Exposure Controls/Personal Protection Airborne Exposure Limits: N/A Engineering Controls: 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. Personal Protection: Safety glasses, gloves, lab coat, dust respirator making sure to use an approved/certified respirator or equivalent. Page 5 of 8
