• Requirements for nonmetallic transfer hoses used for oil under U.S. regulations (46 CFR – verify in current subchapter for tank vessels/transfer hoses) • Difference between a hose defect that makes the hose immediately unacceptable vs. a condition that triggers testing or maintenance • Meaning of hydrostatic testing requirements and inspection intervals for oil transfer hoses

💭 Think About

• Look at each option and ask: does this describe visible physical damage that clearly compromises the hose structure, or a test/inspection issue? • Think about which condition, if seen during a pre-transfer inspection, would require you to reject that hose from service right away, even before any testing. • Consider whether U.S. regulations treat lack of a recent test the same way as obvious structural damage when deciding if a hose is suitable for use.

✅ Before You Answer

• For each option, decide: would this be listed in regulations as a specific reason to remove a hose from service? • Check which conditions clearly expose or damage the reinforcement or indicate serious deterioration of the hose wall. • Verify from the wording whether a failed hydrostatic test and an overdue test date are treated the same way under the suitability criteria.

According to U.S. regulations, which of the following conditions would disqualify a nonmetallic hose as being suitable for use in transferring oil?

A cut in the cover which makes the reinforcement visible

Evidence of internal or external deterioration

A blown gasket when hydrostatic test pressure is applied

The hose has not been tested in the last 180 days
