What is the proper sequence for shutting down a foam transfer line in an emergency?

• A. Stop pump, close discharge valves, isolate power, secure area, begin containment/cleanup, document actions
• B. Open all valves and restart the pump
• C. Disable all safety systems and leave
• D. Notify supervisor only

Answer: (A)

In an emergency, the priority is to quickly stop the foam transfer and secure the area before anything else. Start by stopping the pump to immediately halt fluid movement and reduce pressure. Then close the discharge valves to isolate the line and prevent further discharge or backflow. Next, isolate power to the transfer system to prevent any accidental re-starts and to reduce electrical hazards. Once the system is secured, move to secure the area so that personnel are kept safe and responders can work without interference. After that, begin containment and cleanup to confine the foam and any spilled material and to minimize environmental impact. Finally, document all actions taken for accountability and compliance.
