When are minor repairs and additions not required to be pressure tested?

The correct answer revolves around the protocols established for ensuring safety and compliance regarding gas systems. Minor repairs and additions typically do not require a pressure test when the work is inspected and tested with approved leak-detecting methods. This means that if the repair or addition has been properly assessed using reliable leak detection techniques, it can be considered safe without the need for a full pressure test. This method allows for an efficient approach to ensure safety without unnecessarily extending downtime or complexity of the maintenance process.

Effective leak-detecting methods can accurately identify any potential issues, ensuring that the system remains secure. This is crucial in preventing gas leaks, which can have serious safety implications. Thus, the use of approved leak detection aids in ensuring compliance with safety regulations while allowing for minor work to proceed without the more rigorous process of a pressure test.
