What action is required if a cargo tank is found to have an unsafe condition before unloading?

When a cargo tank is found to have an unsafe condition before unloading, it is essential that a qualified person assesses the situation. This action is crucial because a qualified person has the necessary training and expertise to evaluate the specific issues with the tank, understand the risks involved, and determine the appropriate corrective measures. This ensures the safety of the unloading operation and protects both personnel and the environment from potential hazards associated with liquefied petroleum gas (LPG).

Ensuring a proper assessment by qualified personnel aligns with safety protocols laid out in NFPA 58 and other regulations that emphasize risk management and the prevention of incidents. Simply proceeding with minor repairs or notifying the dispatcher without a thorough assessment could lead to overlooking significant safety issues that could escalate during the unloading process. Therefore, assessing the overall condition and safety of the tank by qualified personnel is a critical step before any further action is taken.
