Disposal: Collect waste in sealed, labeled containers for specialized disposal
Decontamination: Wash spill area with water and detergent, avoid solvent-based washes for safety
Handling: Use proper ventilation to avoid dust, minimize contact with skin and eyes, wash hands thoroughly after handling, avoid eating or drinking in work area
Storage: Store in original tightly-sealed containers in a cool, dry, well-ventilated place, avoid direct sunlight and sources of heat, keep away from strong oxidizing agents and acids, lock storage area to prevent unauthorized access
Incompatible Materials: Strong acids and bases, oxidizing or reducing agents, moisture
Conditions to Avoid: Humidity, open flames, static discharge
Special Requirements: Ensure labeling remains clear and legible, maintain records of inventory for safe chemical management
Occupational Exposure Limits: No established limits for this substance, use general industry standards for nuisance dust (10 mg/m³ for total dust, 5 mg/m³ for respirable dust)
Engineering Controls: Enclosed processes, exhaust ventilation at dust sources, eye wash stations and emergency showers nearby
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), safety goggles, laboratory coat or chemical apron, dust mask or respirator approved for particulates
Hygiene Measures: Do not eat, drink, or smoke while handling, wash thoroughly with soap after handling, clean work clothing regularly
