NAC445A.436. Minimum design criteria: Vats, tanks and other containers which confine process fluids.  


Latest version.
  • Vats, tanks and other containers which confine process fluids and can be inspected for leaks visually do not require double liners if an area for secondary containment equal to 110 percent of the largest container is provided. Vats, tanks or other containers that are partially buried and cannot be visually inspected must have a system to detect leaks.
