Question 83Safety & Environmental - Assistant Engineer

The correct answer is B) cargo tank during Butterworthing. During the Butterworthing process, which is a method of tank cleaning, the agitation of the liquid in the cargo tank can create an electrically charged mist. This charged mist is a result of the electrostatic charge buildup that occurs due to the rapid movement and vaporization of the liquid. The other options are incorrect because they do not involve the specific conditions that lead to the formation of an electrically charged mist, such as the tank cleaning process in a cargo tank.
