Personal Precautions: Evacuate area, use personal protective equipment, avoid contact with spilled material
Environmental Precautions: Prevent entry into drains, surface water, soil, or sewers
Containment Methods: Stop leak if safe, dike and absorb with inert material (sand, earth), transfer to closed containers for disposal
Cleanup Procedures: Wipe up small spills, use non-combustible absorbent for large spills, ventilate area and wash spill site after material pickup
Precautions for Safe Handling: Work in well-ventilated areas, avoid inhaling vapors or direct contact, operate away from heat and sparks, ground containers during transfer
Safe Storage Conditions: Store in tightly sealed containers away from incompatible substances such as strong oxidizers and acids, keep in a cool, dry, well-ventilated location, protect from direct sunlight
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Specific Use Considerations: Avoid prolonged storage at elevated temperature, check containers for leaks or damage on a regular basis
