Gas outlets that do not connect to appliances or future laboratories shall be capped tight, except for which type of devices?

• A. Listed/ labeled, flush-mounted, quick-disconnect devices and gas convenience-outlet.
• B. All outlets must be capped.
• C. Only outdoor outlets may remain uncapped.
• D. Outlets must be open for testing.

Answer: (A)

Unused gas outlets must be capped to prevent leaks, but there is an important exception for devices designed for safe temporary use. If the outlet is a listed or labeled device that is flush-mounted, a quick-disconnect type, or a gas convenience outlet, it may remain available for connection or testing rather than being capped. These devices are manufactured to minimize leak risk and allow safe, controlled temporary use; flush-mounted designs reduce physical hazards, quick-disconnect fittings provide a guarded way to connect and disconnect, and gas convenience outlets are intended for temporary gas needs in labs or similar setups. The other options ignore these safety provisions: some outlets aren’t universally required to be capped, and outdoor-only or testing-only requirements don’t apply as stated.
