Question 1304 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 153.525(b), which states that the vent "must terminate at a vertical height above the weather deck of at least 10 feet." This regulation ensures that any gas or vapor released from the safety relief valves is discharged at a sufficient height to prevent potential ignition sources or hazards on the weather deck. The other answer choices are incorrect because they do not meet the minimum 10-foot requirement set forth in the Coast Guard regulations for this type of venting configuration on barges.
