Who must check the discharge system components prior to unloading from a cargo tank motor vehicle?

The correct answer emphasizes that a qualified person is responsible for checking the discharge system components prior to unloading from a cargo tank motor vehicle. This requirement is critical in ensuring that all components are in safe working order before the unloading process begins. The term "qualified person" refers to someone who has the necessary training, experience, and expertise to assess the equipment and implement proper safety protocols.

By having a qualified individual perform this task, the likelihood of accidents or leaks during the unloading process is significantly reduced. This role typically includes assessing hoses, valves, fittings, and connections for mechanical integrity and ensuring compliance with safety and operational standards set forth by NFPA 58 and other relevant regulations.

While drivers, maintenance technicians, and discharge coordinators play important roles in the overall handling and transporting of liquefied petroleum gas, the specific responsibility of checking the discharge system components is designated to individuals who possess a certain level of expertise to ensure operations are carried out safely. Their specialized knowledge allows for informed judgments about the condition and suitability of the equipment for use during unloading.
