What task should never be performed with an LP gas cylinder?

Moving an LP gas cylinder while it is still connected to an appliance poses significant safety risks. When cylinders are connected to appliances, they are under pressure, and any jarring or movement can cause an unsafe situation. This could lead to a potential gas leak, which creates a hazard for combustion or explosion. It is crucial to detach the cylinder from the appliance before moving it to ensure safe handling and minimize the risk of accidents.

Storing LP gas cylinders in an upright position is actually the recommended practice, as this helps maintain stability and safety when the cylinder is being used or stored. Transporting an LP gas cylinder in a vehicle is permissible, provided that proper safety guidelines are followed, such as securing the cylinder and ensuring it is in a well-ventilated space. Regularly inspecting LP gas cylinders for damage is also a critical maintenance task, ensuring any wear or issues are addressed before they lead to failures or leaks.
