Environmentally Safe, Chemical-Free Fire Protection Systems
- NEW BUILD
The Safespill floor for hangars contains and removes ignitable liquid spills before developing into a pool fire. When a spill occurs, the liquid flows into the hollow floor profiles through specially machined drain holes on the top surface. The internal flushing and suction system then pumps the contained liquid into external containment.
- Solution for new build and existing retrofit (military and commercial) hangars
- PFAS-free with no environmental risk because it is a 100% closed system, using only water
- 5-year warranty with optional renewal
- FM approved, under standard 6090
- Adopted in NFPA 409 2022 Edition as Ignitable Liquid Drainage Floor Assembly (ILDFA)
- On average 20-30 days, dependent on aircraft type, quantity, and hangar type and size
- Minimized downtime
- Solutions available to avoid cutting or modifying existing concrete substrate
- Centrifugal pumps to remove the spilled liquid
- 480V/460V for centrifugal pumps and 120V/110V for control panel
(Not Fire Water)
- 180 GPM (max), including a booster pump or pressure reducer ensuring the correct pressure
- The Safespill floor is designed to utilize municipal water supply.
- A 9” x 16” Safespill floor area can handle 96,000 lbs. or 666 PSI
Spill Containment Tank
- Spilled liquid and flushing water need to be directed to temporary spill containment
- Tank capacity is driven by spill size and drain time.
Spill Containment Calculation Example for a Single B-52 Hangar
Worst Case Scenario (WCS)
|Largest Potential Spill||5,928 gallons||Based on aircraft’s largest fuel tank|
|WCS Spill Flow Rate||400 GPM||Based on a 4” valve failure or 4” puncture in diameter|
|Drain Time||5,928 / 400||= 15 min. (Round up to 30 min. for WCS)|
|WCS Flushing Water||180 GPM / 30 min.||= 5,400 gallons|
|∴ Spill Containment Tank||11,328 gallons||Minimum tank capacity|
UL-142 Double-Wall 15,000-gal Steel Tank – Image shown for reference only.
- Safespill recommends a 15,000-gallon UL-142 double-wall horizontal steel tank, based on a conservative assessment in the above calculation.
- An Oil Water Separator (OWS) is included after the tank for best practices.
Dropped Wing Tank Simulation
This test simulates what happens when a wing tank full of JP-4 drops and instantly releases ignited jet fuel onto the Safespill floor. Fuel is JP-4 equivalent, consisting of
66% kerosene and 33% gasoline.
