70% to pass"Portable" oil tank cleaning machines are usually provided with a water supply from the _______________.
Ainert gas scrubber
Bfire main
Cpotable water supply
Dmucking supply system
AI Explanation
The correct answer is B) fire main. Portable oil tank cleaning machines are typically provided with a water supply from the fire main system on board a vessel. The fire main is a system of piping and fire hydrants that provides a ready source of water for firefighting purposes. This water supply is suitable for use in the oil tank cleaning machines, as it is pressurized and readily available throughout the vessel. The other options are incorrect because: A) an inert gas scrubber is not a source of water supply, C) the potable water supply is for drinking water, not industrial uses, and D) a "mucking supply system" is not a standard term and does not refer to a water supply source for oil tank cleaning.
