How many qualified person(s) must be in attendance at a transfer operation?

In the context of liquefied petroleum gas transfer operations, regulations set forth in the NFPA 58 require that at least one qualified person be present during the transfer process. This individual must be trained and knowledgeable about the specific procedures and safety protocols related to handling LP-gas. The presence of a qualified person ensures that operations can be conducted safely and that any potential hazards can be managed effectively.

Having one qualified person present allows for the proper oversight of the transfer operation, ensuring adherence to safety guidelines and responding promptly to any emergency situations that may arise. While more personnel can increase safety and support during the operation, the requirement for at least one qualified individual is critical for compliance with safety standards and regulations governing the handling and transfer of LP-gas.
