U.S. regulations require cargo pump rooms, on tank vessels handling grades A, B, or C liquid cargo, shall be equipped with power ventilation of the exhaust type. in what amount of time should the ventilation effect a complete change of air?

A not more than 1 minute

B not more than 2 minutes

C not more than 3 minutes

D not more than 5 minutes

AI Explanation

The correct answer is C) not more than 3 minutes. According to U.S. regulations, cargo pump rooms on tank vessels handling grades A, B, or C liquid cargo must be equipped with power ventilation of the exhaust type that effects a complete change of air within 3 minutes. This is specified in the regulations to ensure the prompt removal of any flammable vapors that may accumulate in the pump room, reducing the risk of fire or explosion. The other options are incorrect because A) 1 minute is too short a time for a complete air change, and B) 2 minutes and D) 5 minutes do not meet the regulatory requirement of not more than 3 minutes.
