Firefighting Procedures: Approach from upwind to avoid hazardous vapors; Prevent run-off from entering drains, water courses, or soil
Personal Precautions: Ventilate area, wear appropriate personal protective equipment including gloves and goggles
Environmental Precautions: Prevent further leakage or spillage if safe to do so; Avoid release into water bodies and drains
Cleanup Methods: Collect spilled material mechanically, sweep up and place in suitable closed containers for disposal; Wash contaminated area with plenty of water; Do not flush large quantities into sewage systems
Exposure Controls: Evacuate non-essential personnel; Mark the affected area until clean-up completes
Safe Handling: Handle with care; Avoid generation of dust and prolonged contact with skin or eyes; Wash hands before breaks and after work
Storage Conditions: Store in tightly sealed containers, in a dry, well-ventilated area away from sources of moisture and incompatible substances (strong acids, oxidizing agents)

Hygiene Practices: Do not eat, drink, or smoke during handling; Remove contaminated clothing and protective equipment before entering eating areas
Storage Temperature: Keep between 15°C and 25°C (59°F – 77°F) if possible
Exposure Limits: No established occupational exposure limits; Observe general workplace limits for nuisance dust
Engineering Controls: Use local exhaust or process enclosure ventilation to keep airborne levels below recommended exposure limits
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), splash goggles, lab coat or coveralls; Use a particulate respirator if dust is generated
Thermal Hazards: Protective equipment resistant to corrosive and hygroscopic substances
Hygiene Measures: Routine washing to remove any skin contact, eye wash stations and safety showers in work area
