What steps should be taken to prevent spills during transfer of AFFF concentrate?

• A. Grounding and bonding during transfer, pump at controlled rate, close valves properly, use secondary containment, keep spill kits ready
• B. Do not ground or bond; transfer rapidly
• C. Only use dry methods; no containment
• D. Do not monitor equipment

Answer: (B)

Preventing spills during AFFF concentrate transfer relies on controlling static electricity, managing the flow, and having containment in place. Grounding and bonding the equipment and hoses dissipates static charges that can build up during transfer, reducing the risk of sparks or igniting vapors. Using a controlled pump rate minimizes splashing, surge pressure, and sudden disconnections that can lead to leaks. Closing valves properly prevents unintended flow when connecting or disconnecting lines. Secondary containment provides a barrier to catch any spills and prevent environmental release. Keeping spill kits and absorbents ready ensures quick cleanup if a spill does occur. The other options miss these critical safety steps: not grounding or bonding and transferring rapidly raises static and spill risks, and skipping containment or monitoring leaves spills unaddressed and harder to manage.
