Other Information: Cool exposed containers with water spray. Remove containers from fire area if safe.
6. Accidental Release Measures
Personal Precautions: Use personal protective equipment. Avoid breathing vapors or dust. Provide adequate ventilation.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains or waterways.
Spill Response: Absorb with inert material (sand, earth, vermiculite). Scoop up and place in appropriate container for disposal. Decontaminate spill area with soap and water.
Reference to Sections: For personal protection see Section 8. For disposal see Section 13.
7. Handling and Storage
Handling: Avoid all contact with eyes, skin, and clothing. Do not breathe in vapors or dust. Use only in well-ventilated areas. Wash hands and exposed skin thoroughly after handling.
Storage: Store in tightly closed, original containers in a cool, well-ventilated area. Keep away from heat, sparks, open flames, and strong oxidizing agents. Do not store with incompatible substances (see section 10).
8. Exposure Controls and Personal Protection
