B the pump room is gas-free
C all other compartments in which flammable vapors and gases may exist are closed and secured
D All of the above
AI Explanation

The correct answer is D) All of the above. The use of portable electrical equipment in the pump room on tank barges is prohibited unless the following conditions are met: 1) Spaces with bulkheads common to the pump room are either gas-free, inert, filled with water, or contain grade E liquid. 2) The pump room itself is gas-free. 3) All other compartments in which flammable vapors and gases may exist are closed and secured. This requirement is specified in the regulations governing the safety of tank vessels, which aim to mitigate the risk of fire and explosion in hazardous areas. The other answer choices do not fully encompass the necessary conditions for allowing portable electrical equipment in the pump room, which is why D) is the correct answer.
