Protective Equipment: Firefighters to wear self-contained breathing apparatus and full protective gear
Firefighting Instructions: Move containers from area if safe, prevent run-off from entry into waterways
Personal Precautions: Wear proper protective equipment to minimize dust exposure
Environmental Precautions: Prevent material from entering drains, surface or ground water
Methods of Clean-Up: Sweep or vacuum spillage while avoiding dust; collect in a suitable, labeled container; ventilate area well during clean-up
Handling: Minimize dust generation and accumulation; keep away from incompatible substances; handle with gloves and goggles
Storage Conditions: Store in well-ventilated, dry area away from acids, moisture, and extreme temperatures; tightly seal original container
Incompatibilities: Strong acids and oxidizing agents; prolonged moisture exposure can degrade product
Occupational Exposure Limits: Not established for this compound; general nuisance dust limit: 10 mg/m3 (inhalable), 3 mg/m3 (respirable)
Engineering Controls: Use appropriate local exhaust ventilation or containment
Personal Protective Equipment: Chemical safety goggles, lab coat, suitable gloves (nitrile recommended), dust mask or respirator for handling powders
