When an operator is not in attendance, what should be done to the dispenser?

When an operator is not in attendance, the dispenser should be shut down and secured to ensure safety. This practice minimizes the risk of accidents, leaks, and unauthorized use. By shutting down the dispenser, you effectively prevent any potential hazards from occurring while there is no oversight. Securing the dispenser also helps protect against tampering or misuse in the operator's absence, which is crucial in managing flammable substances like LP-gas.

Leaving the dispenser operational or locked open poses significant safety risks, as it could allow for unintended dispensing or potential spills. Disconnecting the dispenser entirely might not be practical or necessary in every situation, especially if it needs to remain ready for immediate use when the operator returns. Hence, the best approach when the operator is away is to ensure the equipment is safely secured.
