5. Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray
Unsuitable Media: Direct water jets (may spread molten material)
Specific Hazards: Thermal decomposition and burning may release irritating fumes: carbon monoxide, carbon dioxide, organic acids
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, full protective clothing
Firefighting Instructions: Move containers away from fire area if possible; keep cool with water spray; control runoff; avoid inhaling vapors

6. Accidental Release Measures

Personal Precautions: Wear protective gloves, eye protection, and dust mask to limit contact with skin or inhalation of dust
Environmental Precautions: Do not allow spills to reach waterways; prevent from entering drains, soil, surface water
Methods for Cleanup: For solid or granules, sweep or shovel into suitable, labeled containers; for molten material, allow to cool and solidify, then collect; ventilate area
Other Information: Wash spill area with water and detergent to remove residues; dispose in accordance with local regulations

7. Handling and Storage

Safe Handling: Avoid generating dust; handle in accordance with good industrial hygiene; use adequate local exhaust; keep away from heat and sources of ignition
Storage Recommendations: Store in cool, dry, well-ventilated area; keep containers tightly closed and away from incompatible materials (strong oxidizers, acids); avoid moisture contact
Incompatible Materials: Strong oxidizing agents, acids; store away from open flames or hot surfaces
Specific Design Considerations: Use material suitable for contact with natural resins; reserve storage for original containers
