Step-by-step explanation:
Prior to unloading from a cargo tank motor vehicle, the driver must check the components of the discharge system, including the delivery hose assemblies and piping. This is done to ensure that the system is functioning properly and there are no leaks or damages that could lead to accidents or spills.
The driver should visually inspect the hoses and piping for any signs of wear and tear, such as cracks, bulges, or loose fittings. They should also check for any signs of leakage, such as drips or stains. If any issues are identified, the driver should report them immediately and take appropriate actions to rectify the situation.
In addition to visual inspections, drivers may also need to perform pressure tests to check the integrity of the delivery hose assemblies and piping. This involves pressurizing the system and checking for any drop in pressure, indicating a leak. Pressure tests should be conducted according to industry standards and regulations.
