Firefighting Procedures: Cool nearby containers with water spray to reduce pressure build-up, contain run-off to prevent entry to sewers or watercourses
Personal Precautions: Eliminate all ignition sources, use proper personal protective equipment—gloves, goggles, respirator
Environmental Precautions: Prevent spills from entering sewers, waterways, or soil, contact local environmental authorities if large release occurs
Containment Methods: Stop further leakage if safe, dike spilled material with inert absorbent like sand or earth
Cleaning Methods: Collect with non-combustible absorbent, place in suitable containers for disposal, clean area with detergent and water
Safe Handling: Use in well-ventilated areas, avoid creating aerosols or dust, use proper protective clothing, do not eat or drink near product
Storage Conditions: Store tightly closed in original containers, keep in cool, dry place away from direct sunlight and incompatible materials like strong oxidizers
