Clean-up Methods: Sweep or vacuum up, minimize dust, place material in closed container for disposal
Additional Advice: Ventilate area, prevent exposure to children and pets
Handling: Handle in a well-ventilated area, minimize dust, wear personal protective equipment as needed
Storage: Store in tightly sealed container, keep cool and dry, avoid moisture or direct sunlight
Safe Packaging: Use original packaging or airtight containers to prevent contamination
Incompatible Materials: Strong oxidizers, acids, moisture
Hygiene Measures: Wash hands before eating, avoid smoking or drinking near storage/handling zones
Occupational Exposure Limits: No established OELs, general dust limit: 10 mg/m³ TWA (total dust)
Engineering Controls: Use local exhaust ventilation for dust control
Eye Protection: Safety goggles or face shield if dust risk exists
Skin Protection: Laboratory gloves, long sleeves
Respiratory Protection: NIOSH-approved dust mask if airborne dust likely
General Protection: Regular work clothing is usually sufficient in low-risk environments
Environmental Controls: Wastewater treatment and dust filtration for large-scale operations
