Which of the following is typically NOT a function of secondary containment systems?

1. Prevent leaks from releasing into the environment

2. Assess internal tank vibrations

3. Collect leaked product for recovery

4. Provide additional structural support

The correct answer is: Assess internal tank vibrations

A secondary containment system is primarily designed to prevent leaks from releasing into the environment, collect leaked product for recovery, and provide an extra layer of support to the primary containment system. Its main functions include serving as a barrier that contains any leaks that occur, facilitating the recovery of spilled substances, and ensuring that the structural integrity of the containment area maintains safety and compliance with regulations. Assessing internal tank vibrations is not typically a function of these systems. While monitoring tank conditions is essential for overall safety, controlling vibrations falls more under the domain of tank design and structural engineering, rather than functions specifically attributed to secondary containment systems. Therefore, this option stands out as the function that does not align with the primary roles of secondary containment.
