Compressed gas cylinders should be stored upright and secured to prevent tipping for several important safety reasons. Storing cylinders upright helps to ensure that the valve remains at the top, which is crucial since the valve is the part that controls the flow of the gas. If a cylinder were to fall over and the valve were to break, it could lead to rapid gas release, potentially creating a hazard.

Additionally, upright storage minimizes the risk of the cylinder rolling or sliding, which can happen if they are stored horizontally. Securing the cylinders, whether to a wall or a dedicated rack, further enhances safety by preventing them from moving or falling during routine activities or in the event of an earthquake or other disturbances. Properly securing the cylinders also helps to keep them organized and easily accessible for use.

The other options, while they may offer some level of protection, do not provide the same degree of safety. For instance, storing cylinders horizontally could put them at risk of leaking or damage, while a locked cabinet does not address the stability of the cylinders when in use. Lastly, open shelves may lack the necessary restraints to keep the cylinders secure. Therefore, the best practice remains to store compressed gas cylinders upright and secure.
