Question 1032 Deck General

The correct answer is A) when the process is started. When cleaning a tank using the Butterworth process, you should begin to pump out the slops (the liquid and sediment mixture) as soon as the Butterworth cleaning process is started. This ensures that the slops are removed from the tank as the cleaning progresses, preventing them from accumulating and potentially causing issues. The other options are incorrect because: B) waiting until the process is finished would allow the slops to build up in the tank, C) waiting until the end of the drop schedule (the predetermined time for the cleaning process) is too late, and D) waiting until the tank is completely clean is also too late in the process.
