Personal Precautions: Use chemical splash goggles, gloves with adequate breakthrough time, chemical-resistant boots, avoid dust
Environmental Precautions: Prevent from entering waterways, soil, or drains, contain spill with sand or absorbent material
Spill Cleanup: Collect spilled product in sealed containers for disposal, ventilate area, wash site with plenty of water after material pickup, dispose of contaminated absorbent as hazardous waste
Emergency Procedures: Evacuate area of non-essential personnel, stop leak if safe
Handling: Wear eye protection, chemical-resistant gloves and apron, keep containers tightly closed, avoid ingesting or inhaling product
Storage: Store in cool, dry, well-ventilated space, keep away from strong bases, acids, oxidizers, and sunlight, store only in containers approved for chemical storage, inspect regularly for leaks or corrosion
