Special Protective Equipment for Firefighters: Full protective clothing including self-contained breathing apparatus should be worn
Specific Hazards Arising from Substance: Dust may form explosive mixtures with air under unusual conditions, containers may rupture from heat
Personal Precautions: Avoid breathing dust, ensure adequate ventilation, use personal protection including gloves, goggles, dust mask
Environmental Precautions: Prevent spillage from entering drains or watercourses, collect spillage mechanically
Clean-up Methods: Sweep up and place material in a suitable, clearly labeled container for disposal, avoid creating dusty conditions, wash spill area after removal
Handling: Wear protective equipment, avoid skin and eye contact, prevent dust formation, avoid inhalation of powder
Storage Conditions: Keep container tightly closed in a dry and well-ventilated place, store away from incompatible materials such as strong oxidizers, acids, or moisture sensitive chemicals
Other Recommendations: Store in original packaging, label containers clearly and do not reuse for other chemicals
Exposure Limits: No occupational exposure limits established for this material
Engineering Controls: Use local exhaust ventilation when handling powder, keep work area free from dust accumulation
Personal Protective Equipment: Wear safety goggles, chemical-resistant gloves, lab coat, and use approved dust mask or respirator if dust is generated
