California ICC UST Inspector Practice Exam

The shear section of a shear valve in the UDC must be located ______ inches above the top surface of the dispenser.

1. 1

2. 1 1/2

3. 1/2

4. 1/4

The correct answer is: 1/2

The correct answer indicates that the shear section of a shear valve must be located 1/2 inch above the top surface of the dispenser. This specific placement is important for several reasons related to safety and functionality. By having the shear section positioned at this precise height, it ensures that the shear valve can effectively break away in the event of an impact, preventing the release of fuel or other hazardous fluids. This height allows the shear valve to operate as intended, maintaining the integrity of the system while minimizing potential spillage or leakage. The choice of 1/2 inch is derived from industry standards and regulations designed to enhance the safety of fuel dispensing systems. Arranging the valve at this height provides sufficient clearance while aligning with established codes that focus on protecting both the equipment and the surrounding environment. The other options do not meet the regulatory standards or best practices for shear valve installation, potentially compromising safety or efficiency in the event of a disruption.
