After a regulator is installed on an oxygen cylinder, the cylinder valve should always be:

Closed tightly to prevent leakage
Opened all the way to prevent leakage
Opened slightly to prevent leakage
Kept closed until use

The correct answer is: Opened all the way to prevent leakage

The best practice after installing a regulator on an oxygen cylinder is to open the cylinder valve all the way. This ensures that there is a proper flow of oxygen through the regulator and to any connected equipment. By fully opening the valve, any potential leaks that could occur from a partially opened valve are eliminated, as a secure and stable gas supply is established for operations. In addition, an open valve minimizes the risk of the valve seizing or becoming difficult to operate if it is left partially opened for an extended period. Full opening allows the regulator to function effectively at its intended pressure and flow rate, thereby enhancing safety and efficiency in use. It’s important to properly manage cylinder valves, as incorrect handling can lead to dangerous situations, including leaks or pressure loss. Therefore, mastering the procedure of fully opening the valve after regulator installation is crucial for safe operation.
