SuperSafe's Inherent Prevention by Design. The SuperSafe Tank Overfill Protection System employs six redundant safety features in its design and assembly. These standard features include:

  • A large-faced volume gauge calibrated in feet and inches to demonstrate the available The SuperSafe Tank Overfill Protection Systemremaining capacity within the primary tank.
  • A weather-tight sticking hatch on top of the Cylindrical Dike so that the manual fuel level determination can be made (required per API).
  • A fail-safe high-level alarm, not dependent on the volume gauge, that will sound an alarm, flash a beacon and stop the pump motor, Per: NFPA-30 2-10.1b.
  • A fail-safe high-level hydraulic valve built to ANSI B16.5 Standard and meets NFPA-30 2-10.1.1 Emergency independent shutdown system.
  • Emergency overflow vent directly funneling fuel into the annular interstitial space which has a 25% greater capacity than the primary tank.
  • Annular Interstitial liquid sensor to recognize a nonstandard condition and sound an alarm, flash a beacon and stop the pump motor.

The SuperSafe Spill Protection System is composed of:

  • Kamlock and dry-break couplers.
  • Filling adapters installed at an elevated 45 degree angle so that even the smallest drop isn't lost during hose disconnect.
  • Spring loaded full port inlet check valve ensure prevention of reverse flow.
  • A slow-closing hydraulic high-level shutdown valve prevents hydraulic shock to up-stream components.
  • Tank sumping and product supply pipingDispensing or suction piping that is configured utilizing down-stream components of solenoid valves, fire-link valves and shear valves as appropriate.
  • Tank sumping and product supply piping are protected from fuel siphoning with the SuperSafe Antisipon System.
  • All fill, suction, dispensing and vapor recovery piping is secondarily contained in weather-tight, liquid-tight compartment with monitoring ports or liquid detecting sensors where necessary.

The SuperSafe Spill Protection System

The SuperSafe Leak Protection System:

  • Ensures that in the unlikely event of a tank leak, the escaping product would be captured within the Cylindrical Dike. A fail-safe engineered self diagnostic liquid sensor in the dike sump will recognize the non- standard condition and sound an alarm.
  • Features piping that is integral and or fully contained within the weather- tight pumping compartment. The liquid-tight secondary containment capacity is twice the sum of the liquid bearing components' volumetric capacity.

The SuperSafe Vandalism Protection System is a design of prevention.

  • All access to the stored product is lockable - fill and pump compartment doors, all pipe adapter caps, inspection and sticking hatches.
  • Threaded or bolted access is torqued to the maximum allowable - volumetric gauge, bolted ingress manhole, exposed electrical junction boxes, emergency and working vents.
