Environmental Precautions: Contain spill, prevent spread into watercourses, notify relevant authorities if substantial spill occurs
Clean-up Methods: Collect released powder or gel with shovel or vacuum, sweep up and transfer to labeled waste container, wipe area with damp cloth, dispose of in accordance with local regulations
Spill Containment: Use absorbent materials for larger releases, avoid producing dust
Handling: Use in well-ventilated area, avoid dust, do not eat, drink or smoke during use, wash hands after handling, keep containers tightly closed
Storage: Store in cool, dry place, away from direct sunlight and heat, keep separate from strong acids or oxidizers, do not store near food or beverages, use corrosion-resistant containers
Transfer Precautions: Use spill trays or secondary containment
Packaging Materials: High-density polyethylene or glass for prolonged stability
Exposure Limits: No established OSHA/NIOSH limits for chitosan-catechol
Engineering Controls: Local exhaust ventilation, lab fume-hood usage, minimize aerosol generation
