How would you develop an emergency response plan for a chemical spill at an industrial facility?

Emergency response plan elements: hazard identification (chemical inventory, properties, quantities), vulnerability mapping (drainage, groundwater, receptors), prevention measures (containment, monitoring, maintenance). Response procedures: spill detection and notification, initial containment (booms, berms, absorbents), evacuation protocols, PPE requirements, cleanup procedures, and waste disposal. Team structure with responsibilities, communication protocols, and external coordination (fire, pollution control, hospitals). Training and drills schedule. Post-incident assessment and reporting requirements. Documentation of equipment and supplies locations. Integration with facility EHS management system.
