Disposal of Waste: Place material in sealed containers for proper disposal under local regulations
Safe Handling Advice: Handle in well-ventilated areas, use appropriate personal protective equipment, avoid inhalation and skin contact
Technical Measures: Use local exhaust ventilation for dusty operations, seal containers tightly after each use
Incompatible Materials: Strong oxidizers, bases, sodium hypochlorite
Hygiene Measures: Wash hands after handling, do not eat or drink in work area, change contaminated clothing
Storage Conditions: Store in a cool, dry, well-ventilated space, keep away from incompatible chemicals, protect from moisture
Packaging: Use original container or one made of compatible material
Occupational Exposure Limits: No established regulatory limit, keep airborne levels below nuisance dust recommendations (typically 10 mg/m³ total, 3 mg/m³ respirable)
Engineering Controls: Use fume hood or adequate ventilation
Eye Protection: Chemical safety goggles
Hand Protection: Nitrile, latex, or PVC gloves
Respiratory Protection: Dust mask (P2 or N95 recommended) if dust is present
