In the context of UST installations, what is the purpose of a backup safety device?

A backup safety device is essential in underground storage tank (UST) installations primarily to prevent environmental contamination. These devices are designed to act as an additional layer of safety, ensuring that if the primary safety mechanisms fail, there is a secondary system in place to contain any potential leaks or spills. By containing hazardous substances within the tank or controlling their release, backup safety devices help mitigate the risk of soil and groundwater contamination, which can have serious environmental and health implications.

The presence of these devices is crucial in maintaining regulatory compliance and protecting the surrounding ecosystem from harmful substances typically stored in USTs. This proactive approach to safety underscores the importance of not only having primary systems in place but also having adequate backup measures to safeguard against unforeseen failures.
