What are tank vessels handling grade B liquids required to have their cargo pumps separated from all sources of vapor ignition by?
AI Explanation
The correct answer is B) gas tight bulkheads.
Tank vessels handling grade B liquids are required to have their cargo pumps separated from all sources of vapor ignition by gas tight bulkheads. This requirement is specified in the regulations governing the design and construction of tank vessels, as outlined in Title 46 of the Code of Federal Regulations (CFR). The purpose of the gas tight bulkheads is to prevent the potential ignition of flammable vapor-air mixtures that may be present in the cargo area.
The other options, while potentially relevant in other contexts, are not the specific requirement for separating cargo pumps from vapor ignition sources on tank vessels handling grade B liquids. Areas equipped with power ventilation (A), cofferdams (C), and empty cargo spaces (D) do not provide the same level of isolation and containment as gas tight bulkheads.
