Spill Response: Absorb spill with inert material (e.g., vermiculite, sand). Collect and seal in containers for disposal.
Environmental Precautions: Contain and avoid release to environment. Prevent entry to waterways, drains, and soil.
Clean-Up: Decontaminate spill area with detergent and water after material removal.
Handling: Work in well-ventilated fume hoods. Avoid contact with skin and eyes. Prevent inhalation of vapor. Ground and bond containers during transfer.
Storage: Store cool, dry, and well-ventilated. Keep away from ignition sources, heat, oxidizing agents, and acids. Use corrosion-resistant containers, clearly labeled.
