Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Advice: Cool containers with water from a safe distance, prevent runoff into sewers, follow local firefighting procedures
Personal Precautions: Evacuate unnecessary personnel, ventilate area, use personal protective equipment including gloves and goggles
Environmental Precautions: Prevent access to drains, waterways, soil; report significant spills to authorities
Methods for Containment: Absorb spill with inert material (vermiculite, sand), sweep carefully to minimize dust, collect in appropriate closed container
Cleaning Procedures: Wash area thoroughly after removal, dispose cleaning materials safely under hazardous waste guidelines
Handling: Use only in well-ventilated zones, avoid contact with skin and eyes, prohibit smoking and food consumption around the chemical, recommend closed system transfers for bulk handling
