How the Bladder Cabinet System Works:

drum secondary containment cabinetTo use, please use the following system as a guideline:

  1. First raise the drum cabinet 8” from the floor
  2. Slide the fuel storage secondary containment bladder underneath
  3. Finally lower the cabinet on top of it. The inner steel framework is strong enough to keep the cabinet stable. 

How does it work? Small spills are captured inside the polyethylene sump, but what if there is a large spill? This is where the bladder starts working. The bladder will automatically unfurl as the sump fills up to catch overflow for truly complete secondary containment.
