Question 1 of 27070

Q

Each pressure gage used in an oil transfer operation must be accurate to within what percent?

🔍 Key Concepts

• 46 CFR oil transfer and pollution prevention equipment requirements • Manufacturer’s required accuracy tolerance for pressure gages used in cargo/transfer service • Why tighter accuracy is important for overpressure and spill prevention

💭 Think About

• Think about how precise a pressure gage needs to be to safely monitor an oil transfer line near its maximum allowable working pressure. • Compare each percentage with what would be considered practical and realistic for an installed mechanical gage in a marine environment. • Ask yourself: if the gage were off by this percentage, could it reasonably lead to a hazardous overpressure without being noticed?

✅ Before You Answer

• Check 46 CFR Part 39 and related sections for specific pressure gage accuracy language. • Verify whether the regulation specifies accuracy as a percent of full scale, not of the current reading. • Confirm that the required accuracy is tight enough to provide early warning of abnormal line pressure during transfers.
