Overfill devices are critical safety components in fuel storage systems, particularly for underground storage tanks (USTs) at gas stations. These devices are designed to prevent the overfilling of tanks during the transfer of fuel, which can lead to spills, environmental contamination, and safety hazards. Verification of these devices is essential to ensure they are functioning correctly and complying with regulatory standards.

Verification of overfill devices is crucial for preventing accidents and spills in fuel storage systems. Regular testing and maintenance not only help maintain compliance with regulations but also enhance the safety and reliability of fuel operations. Always consult the manufacturer's guidelines and local regulations to ensure that all verification activities are appropriate and thorough.
