How should cylinders awaiting resale be positioned for storage?

Cylinders awaiting resale should be positioned vertically and upright to ensure safety and integrity. This positioning helps to prevent leaks and allows for proper ventilation. Storing cylinders upright minimizes the risk of puncture or damage that might occur if they were laid flat or stored in a horizontal position, where the weight distribution could lead to instability.

In addition, positioning them upright allows for easier access and inspection, which are critical for identifying any potential issues with the cylinders before they are sold or filled. Vertical storage also aligns with regulatory safety practices, which mandate that LP-gas cylinders be stored in a manner that prevents hazards related to pressure relief valves and other critical safety features.

Overall, this method of storage is the most effective for maintaining safety standards in handling and storing propane cylinders.
