Question 1 of 27070

On a barge carrying bulk liquid hazardous cargo, remote controls for quick-closing shut off valves are required in how many location(s)?

🔍 Key Concepts

• Quick-closing shutoff valves on barges carrying bulk liquid hazardous cargo • Locations where crew might need to rapidly stop cargo flow in an emergency (think both at the cargo area and away from the danger zone) • Relevant requirements in 46 CFR dealing with remote controls for cargo shutoff on tank barges

💭 Think About

• If there is a fire or spill at the cargo area, from how many different safe places should the crew be able to operate the emergency shutoff? • Consider whether controls only at the manifold (cargo area) are enough, or whether an additional remote location is required for safety. • Think about redundancy: does the regulation favor a single point of control or multiple separated control points?

✅ Before You Answer

• Verify in 46 CFR for tank barges carrying hazardous liquid cargo where remote quick-closing valve controls must be located. • Check whether regulations specify controls at or near the cargo area AND at a remote, safe location such as the control station or accommodation. • Confirm if the rule uses wording like "more than one" or specifies an exact minimum number of locations.
