Environmental Precautions: Prevent liquid from going to drains, soil, waterways, alert authorities if significant spill occurs
Methods for Clean-up: Absorb spill with inert material (sand, earth, vermiculite), collect and place in suitable container, seal and label waste, wash area with detergent and water
Spill Response: Isolate area, restrict entry, stop leak if possible, contain with dikes
Waste Disposal: Consult regulatory waste handler for instructions
Precautions for Safe Handling: Use only in areas with proper ventilation or fume extraction, avoid inhaling vapors or skin contact, do not eat or drink while using

Special Provisions: Label storage area, secure to prevent unauthorized access
Occupational Exposure Limits: Consult regional authorities (e.g., ACGIH TLV, OSHA PEL for related monomers)
Engineering Controls: Local exhaust ventilation, closed handling systems preferred
Personal Protective Equipment:
- Eye/face protection: Chemical safety goggles, face shield for large scale work
