DC 311 Aqueous Film Forming Foam (AFFF) Transfer Station Operator Practice Test 2026 - Free AFFF Transfer Station Operator Practice Questions and Study Guide

After a transfer, the priority is to finish safely, prevent any residual release, and document what happened so the next shift can pick up without confusion. The best answer includes all the critical actions: check for leaks around fittings and hoses, inspect hoses and connections for wear or damage, verify that valves are closed and the system is isolated, log the transfer details (times, amounts, personnel, conditions), clean up any spills and secure the area to prevent slips and unauthorized access. Each step reduces the chance of environmental contamination, keeps people safe, and ensures proper record-keeping for accountability and regulatory compliance.

The other options miss important parts: testing unrelated equipment isn’t part of the post-transfer check and wastes time; only inspecting the exterior misses internal leaks and connections; skipping documentation removes traceability and could hide incidents or prevent proper handover.
