Personal Precautions: Use personal protective equipment; avoid contact with skin, eyes, and clothing
Environmental Precautions: Prevent entry into sewers, waterways, or soil; block off spill area to minimize environmental damage
Methods for Cleaning Up: Contain spill with absorbent material (sand, earth, inert absorbent); place in labeled waste containers
Decontamination: Wash spill area with detergent and water; ventilate enclosed spaces well after cleanup
Disposal: Follow waste handling protocols as specified by local regulations
Small Spills: Wipe up with absorbent rags and dispose of responsibly
Large Spills: Evacuate waste as chemical hazardous waste; call spill response team if above release threshold
Handling Precautions: Wear suitable gloves and eye protection; use only with adequate ventilation; avoid inhalation of vapors
Safe Work Practices: Do not eat, drink, or smoke during use; practice routine handwashing before breaks
Storage Conditions: Keep container tightly closed in a cool, dry, well-ventilated place
Compatibility: Store away from oxidizing materials and strong acids
Transfer Instructions: Use pumps or dispensers designed for chemical liquid transfer to minimize spills and splashes
Storage Life: Stable under recommended storage conditions, store away from direct sunlight and high heat for best shelf life
Control Parameters: No occupational exposure limits established for diisobutyl adipate
Engineering Controls: Use adequate local exhaust or general ventilation to control exposure below threshold limit values
