Oil Spill Onion Tank

spill containment tankThis spill containment tank provides you with a self-supporting structure that can contain leaks, collect materials during a decontamination process, or even be used as secondary containment for hazardous materials.

Made with an onion or pumpkin shaped structure, these foam collar tanks rise to adapt to the amount of liquid they need to hold. This means that in the event of an spill or leak, tanks can be implemented immediately without any kind of assembly.

Onion tanks are made using fabrics such as PVC or Elvaloy and offer as high resistance to oil and many chemicals. Accessories include cloths and liners for use on rougher surfaces, and drain fittings for easy cleanup.
