In handling gas cylinders, which practice is recommended?

Securing gas cylinders upright is crucial for safety. When gas cylinders are stored or handled, keeping them in an upright position minimizes the risk of tipping over and helps prevent potential leaks or accidents. It also allows for safe and efficient access to the cylinder valves, ensuring that they can be operated properly without obstruction.

Properly securing the cylinders can involve using chains, brackets, or appropriate storage cages to hold the cylinders in place. This practice is particularly important because if a cylinder were to fall, it could sustain damage to the valve or body, leading to hazardous gas leaks or even explosive situations.

While leaving gas cylinders unattended or stacking them poses significant safety risks, and temperature control may be necessary in some contexts but is not as immediately critical as securing them upright. Therefore, the recommended best practice among the choices provided focuses on maintaining order and safety in handling gas cylinders.
