At what pressure should fiberglass secondary-containment be tested?

Fiberglass secondary-containment systems are often tested for structural integrity by applying pressure. The standard procedure typically involves a pressure test to ensure that the system can withstand potential leaks and maintain safety and compliance with regulations. A pressure of 10 Psig is commonly accepted in the field for testing fiberglass secondary containment. This pressure is sufficient to identify any weaknesses or potential failures in the containment system without being excessively high, which could risk damage. Testing at this pressure aligns with industry standards and best practices, ensuring that the containment system is reliable and effective for its intended use.
