Protective Equipment: Self-contained breathing apparatus, full protective gear
Advice for Firefighters: Move containers from fire area if safe, avoid inhalation of combustion fumes

Accidental Release Measures

Personal Precautions: Keep unprotected personnel away, provide adequate ventilation, wear protective equipment
Spill Response: Absorb with inert material such as sand or vermiculite, scoop into labeled containers, seal for waste disposal
Environmental Precautions: Prevent material entering waterways, drains, or soil
Clean-Up Procedures: Detergent and water for area decontamination, dispose waste safely

Handling and Storage

Handling: Use in a chemical fume hood or controlled setting, avoid inhaling dust or vapors, prevent skin and eye contact, keep containers tightly closed
Storage: Store in a cool, dry, well-ventilated place away from incompatible materials, protect from light and moisture, secure storage area to prevent unauthorized access
Incompatibilities: Strong oxidizers, reducing agents, acids, bases, metals
