California ICC UST Service Technician Practice Exam

According to Title 23, which piping components must have secondary containment if installed after a specific date?

1. Gravity product piping

2. Buried piping

3. Pressured product piping

4. Gravity flow piping

The correct answer is: Pressured product piping

In accordance with Title 23 regulations, secondary containment for certain piping components is mandated to prevent leaks and spills from reaching the environment. Specifically, pressured product piping is required to have secondary containment if it is installed after the specified date. The rationale behind this requirement is that pressured product piping is utilized to deliver products under pressure, which can lead to more significant risks if there is a failure or leak. Secondary containment systems are designed to capture any leaks or spills from the primary containment, effectively providing an additional layer of environmental protection. The requirement helps ensure that any leaking substances can be contained and managed before they can escape into the surrounding environment, which is crucial for compliance with environmental safety standards. This requirement emphasizes the heightened risks associated with pressured systems compared to gravity flow systems and other types of piping. Understanding which components require secondary containment is essential for UST technicians, as it directly ties into compliance with environmental regulations and the overall safety of underground storage tank systems.
