Question 1030 Deck General

The correct answer is C) 10 feet. The requirement for the minimum vertical height of branch venting from safety relief valves on barges is specified in 46 CFR 39.20-9, which states that the vent outlet must be at least 10 feet above the weather deck. This is to ensure that any released gas is discharged at a safe height, reducing the risk of the gas accumulating on the deck or near potential ignition sources. The other answer choices are incorrect because 6 feet (A) and 8 feet (B) do not meet the 10-foot minimum requirement, while 12 feet (D) exceeds the minimum without providing any additional safety benefit.
