What is the purpose of integral secondary containment in a protected aboveground tank?

The purpose of integral secondary containment in a protected aboveground tank is to prevent spills from reaching the environment. This type of containment system is designed to catch any leaks or spills that may occur from the primary tank, ensuring that hazardous substances do not escape into the surrounding area. This is crucial for environmental protection and helps mitigate the risk of soil and water contamination, which could have significant health and ecological consequences.

Secondary containment is often a regulatory requirement, especially for tanks that store hazardous liquid materials. It is an essential component of safety management practices in facilities that handle potentially harmful chemicals or substances, and it plays a key role in risk management strategies. The primary focus is on protecting the environment and public health, making this option the most relevant to the function of integral secondary containment.
