Accidental Release Measures

Personal Precautions: Use protective equipment, ensure adequate ventilation, avoid dust or vapor formation
Environmental Precautions: Prevent entry into drains or waterways. Avoid soil contamination.
Small Spills: Absorb with inert material such as sand or earth, collect for proper disposal
Large Spills: Dike area to prevent spreading, collect and contain for disposal
Clean-Up Methods: Sweep up and shovel into suitable disposal container. Wash the spill site with plenty of water after material pickup.

Handling and Storage

Handling: Avoid inhaling dust, vapor or mist. Prevent contact with eyes and skin. Wear appropriate PPE. Use only in well-ventilated areas.
Storage: Store in tightly closed container, in a dry, cool, and well-ventilated location away from incompatible substances, such as strong oxidizers or acids. Protect from moisture and direct sunlight.
