Which of the following tasks would NOT typically be performed in a vault?

Storing gas is not a typical task performed in a vault. Vaults are primarily designed for the protection and housing of equipment and components that enable the safe distribution of gas, rather than serving as storage spaces for the gas itself. Instead, gas is usually stored in regulated storage facilities or lines designed to maintain the required pressure and safety standards.

Monitoring pressure, housing regulators, and facilitating maintenance checks are all essential tasks associated with vault operations. Monitoring pressure ensures that the gas system remains within safe operating parameters, housing regulators serves to manage and control gas flow and pressure, and facilitating maintenance checks is crucial for ongoing safety and functionality. Each of these tasks directly relates to the operational and safety requirements necessary for gas distribution, while storing gas is functionally separate from the vault's intended purpose.
