Protective Equipment: Firefighters should wear self-contained breathing apparatus and standard protective clothing.
Advice for Firefighters: Move exposed containers from area if it is safe, use water to cool nearby containers, avoid breathing dust or fumes, keep run-off water out of sewers and water sources.

Accidental Release Measures

Personal Precautions: Restrict access to the area, wear appropriate PPE, avoid generating dust.
Environmental Precautions: Prevent contamination of water bodies, drains, or soil.
Method for Clean-up: Sweep up and place in labeled, tightly closed containers for disposal, ventilate the area, wash spill site after material pickup is complete, decontaminate clothing and equipment.
Reference to Other Sections: For disposal see relevant section below.

Handling and Storage

Safe Handling: Handle in well-ventilated space, minimize dust creation, avoid inhalation and skin/eye contact, use local exhaust if available, use with caution and avoid eating, drinking, or smoking.
