What must be inspected on a pressurized hose assembly?

Inspection of a pressurized hose assembly is crucial for ensuring safety and reliability in operations involving liquefied petroleum gas (LPG). The correct answer emphasizes that cuts, scratches, blisters, and other physical defects must be thoroughly checked.

These imperfections can compromise the integrity of the hose, making it susceptible to leaks or failures under pressure. Regular inspection helps to identify any wear and tear that could lead to hazardous situations, ensuring that the hose assembly remains safe to operate.

While other aspects such as connectors, hose length, and color coding can also be important, they do not directly relate to the immediate structural condition and safety of the hose itself. The focus on visible damage like cuts and blisters is critical for preventing accidents and ensuring that the hose assembly performs as intended under pressurized conditions.
