California ICC UST Inspector Practice Exam

Pressurized piping with secondary containment must be tested for a release of what minimum capacity?

1. 0.005 gph

2. 0.01 gph

3. 0.1 gph

4. 0.1 gallons

The correct answer is: 0.1 gph

The requirement for testing pressurized piping with secondary containment is specified to ensure that any potential release of hazardous materials is detected at a minimum capacity. The correct capacity of 0.1 gallons per hour (gph) indicates a level of sensitivity necessary to identify even small leaks that could pose environmental or safety risks. This threshold reflects industry standards aimed at maintaining safety and compliance with regulatory agencies. Smaller release rates, such as 0.005 gph or 0.01 gph, may not provide the same assurance regarding the detection of leaks, which is critical in preventing contamination and safeguarding public health. In the context of pressurized systems, the chosen capacity of 0.1 gph allows for a balance between practical testing methods and the requirement for regulatory compliance. Understanding this value is significant for inspectors, as it informs their testing procedures and helps ensure that facilities adhere to the necessary safety standards.
