What should be done to each gas outlet after installation?

After the installation of each gas outlet, it is crucial to cap or plug it closed immediately to ensure safety and prevent any potential gas leaks. This practice helps to protect the system from contamination and external elements that could compromise its integrity. If outlets are left open or improperly secured, there is a significant risk of gas escaping, which could lead to hazardous situations, including fire or explosion risks. Additionally, capping or plugging the outlet serves as a clear indicator that the outlet is not currently in use, reducing the likelihood of accidental connections or misuse.

Other options may seem plausible but do not offer the same level of safety. For example, leaving an outlet open for inspection can pose immediate risks if gas flow is inadvertently activated. Covering an outlet with a protective shield does not provide the same safety measures as capping it, as it could still be vulnerable to gas leaks. Marking an outlet for future use is useful for labeling, but without proper sealing, it does not mitigate the risks associated with gas outlets.
