What is an essential action before connecting a non-flammable gas cylinder for use?

Verifying that the cylinder is free from leaks is essential before connecting a non-flammable gas cylinder for use. This action ensures the safety of the environment and individuals handling the cylinder. Gas leaks can lead to hazardous situations, including the risk of pressure build-up, which can cause the cylinder to rupture or release gas unexpectedly.

Conducting a leak check is a critical safety measure that helps prevent accidents, reduces the risk of injury, and ensures that the gases will perform as expected without the risk of escaping into the atmosphere. This step is a standard procedure in handling pressurized gas cylinders and is emphasized in safety protocols to maintain a safe workspace.

While checking the cylinder for proper branding is important for identifying the type of gas and ensuring appropriate handling procedures, it does not directly address the immediate safety risks associated with leaks. Ensuring that a cylinder is out of date or determining its weight is less relevant for immediate operational safety compared to confirming the integrity of the cylinder and the absence of leaks.
