What should be done if an unexpected pressure drop occurs during the delivery process?

In the event of an unexpected pressure drop during the delivery of LP gas, the proper course of action is to stop the transfer immediately and investigate the cause. This is critical for safety and operational integrity. A pressure drop can indicate a potential leak, a valve malfunction, or other issues that could pose hazards, including the risk of fire or explosion. Stopping the delivery allows for a thorough inspection to identify any problems that may have arisen, ensuring that corrective actions can be taken before resuming operations.

Continuing the delivery without addressing the pressure drop could exacerbate any existing issues and put personnel and equipment at risk. Increasing the flow rate could also lead to dangerous conditions or further complicate an already concerning situation. Simply documenting the incident without investigating it ignores the potential risks associated with LP gas handling and compromises both safety and compliance with regulations. Thus, halting the transfer and investigating is the appropriate and responsible response.
