Define "quick release" in UST terminology.

In UST (Underground Storage Tank) terminology, "quick release" refers to the fast expulsion of product that may lead to overflow or spill incidents. This definition highlights the potential hazards associated with rapid product release, which can occur during operation or maintenance of UST systems. When product is released quickly, there is a significant risk that the spillage may exceed the tank's capacity or the designed safe handling measures, leading to environmental contamination and safety issues.

Quick releases can happen due to equipment failure, human error, or malfunctioning safety systems, and they are a major concern because they can lead to immediate dangers, including fire hazards or adverse environmental impacts. Understanding the implications of a quick release is crucial for UST operators to ensure they can effectively manage risks and implement appropriate safety measures. The focus on the urgency and danger associated with this type of release distinguishes it from other terms related to controlled or standard operations within UST practices.
