Chemical tankers commonly use \"closed gauging systems\". What is the particular safety design feature of such equipment?
It allows the contents of a tank to be measured only after the tank has been fully ventilated.
It requires the operator to open a small inspection hatch before taking each measurement.
It allows tank measurements to be taken only when cargo operations have been stopped.
It allows the contents of a tank to be measured without any lids being opened, so protecting the operator from the possible release of any harmful vapours.
What is the purpose of the special two-way valves mounted on towers at a given height above the cargo deck of a chemical tanker?
When appropriately set, they automatically prevent excessive pressure in a cargo tank by venting vapours through the cargo lines and relieve excessive vacuum.
When appropriately set, they automatically maintain a constant pressure in a cargo tank by recirculating vapours into the tank and relieve excessive vacuum.
When appropriately set, they automatically prevent excessive pressure in a cargo tank (carrying harmful vapours away at a safe height) and relieve excessive vacuum.
When appropriately set, they automatically prevent excessive pressure in a cargo tank by venting vapours into the atmosphere at deck level and relieve excessive vacuum.
