Special Protective Equipment: Firefighters should use self-contained breathing apparatus
Fire Hazards: Melts and may flow, producing dense smoke; dust may present explosion risk
Firefighting Instructions: Cool containers exposed to fire with water; avoid breathing fumes

Accidental Release Measures

Personal Precautions: Wear protective gloves, goggles, dust mask if powder present
Environmental Precautions: Prevent release into drains or watercourses
Methods for Cleanup: Sweep up solid material, avoid dust, use non-sparking tools
Spill Handling: Transfer collected material to suitable waste container
Small Spills: Mop or wipe up, wash residue with water
Large Spills: Use industrial vacuum or shovel, ventilate area

Handling and Storage

Handling: Avoid contact with skin and eyes; avoid creating dust clouds; use with proper ventilation
Storage: Store in cool, dry place away from heat, sparks, open flames, strong oxidizers, acids
Packaging Materials: Use original, tightly closed container
Special Conditions: Protect from moisture and sunlight, keep away from food products
