Cleanup Methods: Absorb with inert material (sand, earth), collect in suitable containers, clean contaminated area with water and detergent
Precaution During Handling Spills: Avoid breathing vapor or mist, ventilate spill area

7. Handling and Storage

Handling: Use with local exhaust ventilation; avoid prolonged or repeated skin contact
Storage Requirements: Keep container tightly closed in a cool, dry, well-ventilated area, away from sources of ignition, strong acids, and oxidizing agents

Other Precautions: Maintain good industrial hygiene standards, wash thoroughly after handling

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific limits established by OSHA, ACGIH, or EU authorities
Engineering Controls: Ensure adequate ventilation; use process enclosures or local exhaust
Personal Protective Equipment - Eyes: Safety glasses with side-shields or goggles
Personal Protective Equipment - Skin: Chemical-resistant gloves (nitrile or neoprene), protective clothing
Personal Protective Equipment - Respiratory: Not normally required unless generation of vapor, aerosol, or mist; then use a NIOSH-approved respirator
Hygiene Measures: Avoid contact with skin, eyes, and clothing; wash hands after handling
