Environmental Precautions: Prevent entry to drains, surface water, and ground water, signal to local environment protection departments if significant quantity is released
Safe Handling: Wear protective equipment during all handling, avoid breathing dust, practice good industrial hygiene such as washing hands after use
Technical Measures: Use effective exhaust ventilation or local air extraction, keep work surfaces clean
Storage Conditions: Store in original tightly closed container, dry, cool, and well-ventilated facility, separate from oxidizers and acids
Incompatible Materials: Strong oxidizers, strong acids, avoid storage near reactive chemicals
Other Precautions: Keep out of reach of children and untrained personnel
Engineering Controls: Mechanical ventilation, laboratory fume hood as primary means to reduce exposure
Respiratory Protection: Use properly fitted particle respirator or mask at least N95 standard if handling powders
Hand Protection: Chemical-resistant gloves such as nitrile or neoprene
Eye Protection: Safety goggles with side shields, face shield for large scale operations
Skin Protection: Laboratory coat, long sleeves, full-length trousers, closed shoes
Hygiene Measures: Wash hands before eating, refrain from touching mouth or face after handling, remove contaminated garments before entering communal areas
