What pressure is required for fiberglass secondary-containment testing?

For fiberglass secondary-containment testing, a pressure of 10 Psig is required. This pressure level is critical for ensuring that the integrity of the secondary containment system is verified. The testing process assesses the ability of the secondary containment to hold liquid in the event of a leak from the primary tank, thereby preventing environmental contamination.

Maintaining a 10 Psig pressure allows for the identification of any potential weaknesses or breaches in the fiberglass material. This standard is set to ensure that any defects can be detected before the system is put into use, providing a reliable safeguard for stored substances. Thus, adhering to this testing pressure is essential for compliance with safety regulations and for the protection of public health and the environment.
