California UST System Operator Practice Test

What is required for pressurized piping in terms of leak detection?

1. An automatic line leak detector must be used

2. Manual checks are sufficient

3. Inspection every month

4. No specific requirements

The correct answer is: An automatic line leak detector must be used

For pressurized piping systems, an automatic line leak detector is crucial because it continuously monitors for leaks and provides immediate alerts if a leak is detected. This automatic detection system is required by regulations to ensure the integrity of the piping and to prevent environmental contamination. The use of automatic monitors minimizes the chances of human error that can occur with manual checks and ensures that any leaks are identified and addressed promptly. This is particularly important in a pressurized system where the risk of spillage is higher and can lead to significant safety and environmental hazards. While manual checks and inspections can be useful, they typically do not provide the same level of assurance as automatic detection methods, which are designed to operate continuously and respond in real time. Regulations are structured to prioritize safety, and the implementation of automatic leak detection fulfills this requirement effectively. Therefore, the necessity of having an automatic line leak detection system stands out as a critical measure for maintaining the safety of pressurized piping in the UST system.
