Cleanup Procedures: Collect residue in suitable closed containers for disposal, wash area with soap and water, ventilate thoroughly, dispose waste under local regulations
Preventative Actions: Isolate hazard zone, use spark-proof tools, remove ignition sources, keep unnecessary personnel from contamination
Handling Precautions: Wear personal protective equipment including gloves, safety goggles, lab coat; use only in well-ventilated area; avoid inhaling vapors and skin contact; never eat, drink, or smoke during use; ground and bond containers; prevent static discharge
Storage Conditions: Keep container tightly closed in a cool, dry, and well-ventilated place; store away from direct sunlight, UV sources, heat, and moisture; separate from oxidizing agents, acids, and peroxides; store in original or compatible approved packaging
Incompatibilities: Strong oxidizing materials, strong acids, free radical initiators, and UV-light sources
Specific Storage Requirements: Maintain temperature between 15 and 25°C; install local monitoring instruments for vapor detection if large quantities are stored
Additional Precautions: Keep only in original container, regularly check for container leaks, avoid overfilling containers
Exposure Limits: No established exposure limits for 1,10-Decanediol Diacrylate; monitor for acrylate vapors in working area
Engineering Controls: Use local exhaust or process enclosure to limit vapors; install explosion-proof ventilation; employ air monitoring if handling large volumes
Respiratory Protection: Wear full-face organic vapor cartridge respirators for high concentrations or inadequate ventilation

Aquatic Toxicity: Harmful to aquatic life, toxic to fish and aquatic invertebrates with possible long-term adverse effects
Persistence and Degradability: Not readily biodegradable, breaks down slowly in soil or water by abiotic and microbial action
Bioaccumulation: Low potential, moderate partition coefficient (log Kow 3.5-4.5), but repeated exposure may still pose risk in aquatic environments
