In non-metered delivery service, what is the required proximity an operator must maintain from the cargo tank while having an unobstructed view of the tank and delivery hose?

The required proximity for an operator in non-metered delivery service to maintain an unobstructed view of the cargo tank and delivery hose is set at 25 feet. This distance is important for ensuring safety during the delivery process. It allows the operator to effectively supervise the operation, monitor any potential hazards, and respond quickly in case of an emergency. The guideline seeks to minimize risks associated with liquefied petroleum gas deliveries by ensuring clear visibility, which is crucial for detecting leaks or other issues that could arise during the transfer process.

Selecting 25 feet as the correct distance aligns with established safety protocols in the NFPA 58 code, emphasizing the need for operators to be close enough to manage the delivery safely yet far enough to avoid potential dangers. This balance is vital for maintaining safety standards during the transfer of propane or other liquefied petroleum gases.
