In accordance with Coast Guard Regulations (33 CFR), each pressure gage used in fuel transfer operations must be calibrated to indicate pressure within what percent of the actual pressure?
• 33 CFR fuel transfer equipment requirements • Accuracy requirements for pressure gages used during oil/fuel transfer • Why tight control of pressure is important for pollution prevention
• Is the Coast Guard more concerned with very tight accuracy or just a general indication? Think about how critical pressure readings are during transfers. • Compare the percentages: which values would be considered typical calibration tolerances for safety‑critical instruments? • If a gauge is off by the largest percentage listed, could that realistically allow unsafe over‑pressure without being noticed?
• Look up the specific section in 33 CFR Part 155 that covers transfer hose and pressure gage requirements. • Verify the exact wording about calibration accuracy for each pressure gage used during fuel or oil transfer. • Confirm that the percentage is expressed as a maximum allowable error from the actual pressure.
