ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Environmental precautions Methods and materials for containment and cleaning up See section 8 for recommendations on the use of personal protective equipment. Do not let product enter drains. Any release to the environment may be subject to a federal/national or local reporting requirements. Neutralize spill with soda ash or lime. Absorb neutralized spill with vermiculite or other inert absorbent material, then place in a suitable container for disposal. Clean surfaces thoroughly with water to remove residual contamination. Dispose of all waste and cleanup materials in accordance with regulations. Containers, even when empty, will retain residue and vapors. 7. HANDLING AND STORAGE Precautions for safe handling See section 8 for recommendations on the use of personal protective equipment. Use with adequate ventilation. Wash thoroughly after using. Keep container closed when not in use. Conditions for safe storage, including any incompatibilities Store in cool, dry well ventilated area. Keep away from incompatible materials (see section 10 for incompatibilities). 8.
