According to the regulations, what type of gauging is required for a cargo of butadiene?
AI Explanation
The correct answer is B) Restricted.
According to the regulations, cargo of butadiene requires restricted gauging. This means that the cargo tanks must be equipped with restricted tank gauging devices, which only allow for limited access to the cargo tank and restrict the release of cargo vapors. This is necessary for the safe handling and transport of butadiene, which is a flammable and potentially hazardous cargo.
The other options are incorrect because: A) Closed gauging is not required for butadiene, as it is a less restrictive method. C) Open gauging is also not permitted, as it would allow for excessive vapor release. D) There is a specific gauging requirement for butadiene, so "None" is not the correct answer.
