  • Confirm chemical compatibility of product being stored with that of the polyethylene tank and fittings.
  • Tanks are to be used at atmospheric pressure only. Make sure tanks are vented as required to prevent pressure or vacuum from developing.
  • Prevent excessive heat near or inside the tank. Polyethylene tanks are designed for a maximum continuous temperature of 70° F.*
  • Have and use Material Safety Data Sheets (MSDS) for the product being stored.
  • Regard tanks as confined spaces.Follow proper entry procedures.
  • Do not stand on tank domes as the surface is flexible and slippery.
  • Do not move tanks while holding liquid and never allow personnel under a tank when it is being lifted!


  • Locate the tank wisely. Protect personnel from chemical danger in the event of a leak and protect the tank from traffic damage and excessive heat. Tanks are designed for above ground use only.
  • Utilize adequate secondary containment according to particular chemical danger and governmental and industry requirements.
  • Fully support the entire bottom of the tank on a clean, smooth concrete foundation. Failure to provide proper foundation and support constitutes a misuse of the tank and will void your warranty.
  • Fill the usable capacity of the tank with water and hydro test up to a minimum of 5 hours after installation and before product is introduced to ensure tank and fitting integrity.
  • Install labels for chemical warning that complies with all local, federal and OSHA requirements.


  • Temperature – Tank specific gravity ratings based on product temperature of 70° F.
  • Pressure – Atmospheric pressure must be maintained in tank at all times; vacuum must = 0.
  • Make sure tank is properly vented for the type of material and flow rates expected.
  • Plumbing – Flexible connections REQUIRED to preserve warranty.


  • Tanks should be inspected on a routine basis.
  • Clean the exterior and interior of the tank.You cannot properly inspect a dirty tank.
  • Inspect the exterior and the interior of the tank for cracking and brittle appearance.
  • Pay particular attention to areas around fittings and where different planes of the tank radius into one another.
  • A bright light source should be used to inspect the interior from the man way opening to avoid a confined space entry.
  • Inspect fittings and exterior gaskets for leaks and signs of general corrosion and deterioration.

* EXTREME CAUTION: Consult Customer Service on any applications where continuous use is above 70° F.

DISCLAIMER: Gallonage/size disclaimer volume and unit measurements are subject to variances due to thermal expansion, contraction and general molding tolerances.
