Firefighting Instructions: Remove containers from fire area if safe. Cool exposed containers.
Explosion Data: Dust may form explosive mixture with air under certain conditions.
Personal Precautions: Avoid dust formation. Avoid breathing vapors, mist, or dust. Wear appropriate personal protective equipment such as gloves, goggles, and coveralls.
Environmental Precautions: Prevent further leakage if safe to do so. Do not allow product to enter drains, waterways, or soil.
Methods for Containment and Cleanup: Sweep up, place in suitable, tightly closed, labeled container for disposal. Use non-sparking tools. Wash spill area with water after material pickup is complete.
Reference to Other Sections: See exposure controls and disposal considerations sections for additional guidance.
Safe Handling Advice: Avoid contact with skin, eyes, and clothing. Minimize dust generation. Use only in well-ventilated area. Keep container tightly closed when not in use. Open and handle containers with care.
