Clean Up Procedures: Collect in closed, labeled containers, ventilate area, dispose according to regulations
Decontamination: Wash spill area with water and detergent after cleanup
Precautions for Safe Handling: Use in well-ventilated places, ground/bond containers, avoid skin and eye contact, keep away from ignition sources
Storage Conditions: Store in cool, dry, fire-proof areas, tightly closed containers, use lights/exhausts with explosion-proof features
Incompatible Materials: Strong oxidizers, acids, bases, free radical initiators
Special Practices: Keep away from food and drinks, label containers clearly, keep out of reach of children
Occupational Exposure Limits: No specific limits established; minimize exposure as for other acrylate monomers
Engineering Controls: Use local exhaust ventilation, maintain eye wash station, design closed systems for transfers
Personal Protective Equipment: Gloves (nitrile, neoprene), goggles or face shield, chemical resistant clothing, approved respirator for high vapor areas
