Hazardous Combustion Products: Oxides of nitrogen and carbon, irritant gases
Personal Precautions: Wear suitable protective equipment, limit access to affected area, avoid dust formation
Environmental Precautions: Prevent entry into waterways, drains, or sewers; avoid soil contamination
Containment Methods: Collect spilled product with a dustless method (such as hepa-filter vacuum or wet sweeping), transfer to closed, properly labeled container for disposal
Cleanup Procedures: Ventilate area, wash spill residue with water and detergent, avoid use of solvents
Handling: Wear chemical-resistant gloves, safety goggles, and appropriate lab clothing; avoid inhaling dust or fumes; use local exhaust ventilation when handling bulk material
Precautions: Do not eat, drink, or smoke while handling; wash hands before breaks or at shift end
Storage: Store in tightly closed, clearly labeled containers at controlled room temperature (15–25°C); keep in well-ventilated area, away from incompatible materials such as oxidizers, acids, strong bases
Storage Life: Consult manufacturer for shelf-life data; protect from direct sunlight and excessive heat
Incompatibilities: Acids, alkalis, strong oxidizers may react adversely
