🔍 Key Concepts

• 46 CFR requirements for cargo tank barges and venting of cargo vapors • Purpose of branch venting from safety relief valves (getting vapors away from people and ignition sources) • Typical minimum vertical clearance above the weather deck for gas discharge on tank barges

💭 Think About

• Think about why vapors must be discharged well above the deck — what are we trying to protect, and how far away from personnel and equipment is usually considered safe in the regulations? • Consider whether the Coast Guard usually picks lower or higher heights when dealing with flammable or toxic vapors over a working deck. • Compare the answer choices to what you remember from other vent height requirements on tank vessels and barges — are they usually just a little above head height, or significantly higher?

✅ Before You Answer

• Identify the specific 46 CFR part that covers design and construction of cargo tank barges and vent systems (not general deck equipment). • Verify the exact wording: "branch venting from safety relief valves on barges shall be constructed to discharge the gas" at what minimum vertical height above the weather deck. • Check that the value you choose is clearly above normal person height and consistent with similar vent/relief discharge height requirements in the same part.
