Fire and Explosion Hazards: Vapors are heavier than air, may travel along the ground to ignition sources; container may explode in heat of fire
Advice for Firefighters: Use water spray to cool containers, keep out of drains to prevent environmental contamination
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors, use protective equipment including gloves and goggles
Environmental Precautions: Prevent spillage into rivers, drains, soil; notify authorities if significant amount enters watercourse
Clean-up Methods: Contain spill with inert material such as sand or vermiculite, collect in closed labeled containers for disposal, wash spill site with plenty of water after material pickup completed
Reference to Other Sections: See Sections on Handling, Disposal and Exposure Controls for detail
Good Practice: Handle in well-ventilated area, avoid contact with skin, eyes, clothing; ground/bond container and equipment to prevent static discharge
