DC 311 Aqueous Film Forming Foam (AFFF) Transfer Station Operator Practice Test

The key idea is to act quickly to control the incident, limit exposure and environmental impact, and document what happened. Start by stopping the transfer and isolating the leak at its source to prevent more product from flowing. Then deploy the spill kit and begin containment to keep the liquid from spreading—use absorbents, barriers, and dikes as appropriate to keep the spill within a controlled area. Next, assess hazards to understand risks to people, property, and the environment, including any flammability, toxicity, and potential interactions with nearby materials or drains. After that, report the incident per the written SOP so the right people are informed and regulatory requirements are met. Finally, document all details of the incident—what was spilled, actions taken, timelines, and any corrective actions—so the event can be reviewed and future prevention planned. These steps are essential; continuing the transfer, rerouting the flow, or ignoring the leak would permit the situation to worsen and increase risk.
