What does the term "cap all outlets" require regarding gas outlet installations?

Close all outlets with a valve
Seal outlets with a cap or plug immediately after installation
Isolate all outlets with manual shut-off valves
Label all outlets for identification

The correct answer is: Seal outlets with a cap or plug immediately after installation

The term "cap all outlets" specifically refers to the requirement to seal gas outlets with a cap or plug immediately after installation. This practice is essential for safety and to prevent the unintended release of gas. By sealing the outlets, you ensure that no leaks can occur before the system is connected to a gas appliance or before it is put into service. This is a preventive measure to protect against hazards such as fire or explosion, which can arise from gas leaks. Other considerations regarding gas installations might include closing outlets with valves, isolating them with shut-off valves, or labeling for identification; however, these do not directly address the immediate need to secure the outlets post-installation. Therefore, the focus of the term here is on the immediate physical sealing of outlets as a critical safety step in the installation process.
