The recommended handling practice for compressed gas cylinders during use is to keep them upright and secured. This approach is crucial for safety reasons. When gas cylinders are stored upright, it reduces the risk of them tipping over, which could cause damage to the cylinder valve or lead to a gas leak. Securing the cylinders with chains, straps, or clamps is also essential to prevent them from falling or being knocked over, especially in active work environments. Maintaining the cylinders in an upright position ensures that the pressure relief device operates correctly and minimizes the potential for accidents or hazards associated with gas leaks.

The other practices mentioned, such as laying them flat on the ground, rolling them for movement, or storing them in direct sunlight, pose significant safety risks. Laying cylinders flat can cause damage to the valve, and rolling them can lead to uncontrolled movement, increasing the risk of accidents. Storing cylinders in direct sunlight can lead to temperature increases that may raise the internal pressure and increase the likelihood of failure or rupture. Therefore, handling compressed gas cylinders upright and secured is vital for ensuring safety in the workplace.
