For small airport ground support fuel depots-critical hubs storing aviation gasoline, ground support vehicle fuel, and diesel (10–40m³) to power tugs, fuel trucks, and maintenance equipment-the FP Series Fluoroprotein Foam Concentrate delivers reliable fire protection. These compact depots face unique Class B hydrocarbon fire risks: fuel spills during ground vehicle refueling, fuel truck hose ruptures, temporary tank overflows, and leaks on concrete tarmacs. Unlike large airport fuel terminals, they operate in open tarmac environments, rely on portable, corrosion-resistant fire-fighting gear, and adapt to temperatures from -15℃ to 35℃. Standard protein foam often fails here: it solidifies above -10℃, clogs portable sprayers with viscosity >50 MPas, and breaks down quickly in tarmac conditions. The FP Series (FP 3% (-16℃) and FP 6% (-20℃)) solves these issues with low-freezing, low-viscosity, corrosion-resistant formulations, complying with NFPA 11 and airport safety regulations.
1. Model Match for Small Airport Ground Support Fuel Depots
| Airport Fuel Zone Type | Compatible FP Model | Key Advantages |
|---|---|---|
| Ambient Refueling Zones (10–35℃) | FP 3% (-16℃) | 6.8±1 expansion ratio (covers 460–860m² diesel spills); ≤30 MPas viscosity (flows through corrosion-resistant portable sprayers and 40mm hoses) |
| Low-Temp Storage Zones (-10–8℃) | FP 3% (-16℃) | -16℃ freezing point; 5.7(1±20%) min 25% drainage time (sustains foam blanket in cool tarmac conditions) |
| Ultra-Cold Tarmac Zones (-15–-10℃) | FP 6% (-20℃) | -20℃ freezing point; 7.1±1 expansion ratio (insulated foam for aviation gasoline fires in cold tarmac environments) |
2. Ambient Diesel Spill (Small Airport, UK, 28℃)
A 640m² diesel spill occurred at a small airport ground support fuel depot during a tug refueling, caused by a ruptured hose from tarmac movement. The spill spread toward a nearby fuel truck fleet and electrical control panel, with tarmac dust accelerating vapor spread. Staff deployed FP 3% (-16℃) via corrosion-resistant portable foam sprayers:
Its ≤30 MPas viscosity ensured smooth flow through 42m corrosion-resistant hoses, reaching the spill in 34 seconds-33% faster than standard protein foam, avoiding clogging in tarmac gear.
The 6.8±1 expansion ratio formed a corrosion-resistant foam blanket, fully covering the spill in 1.5 minutes. It maintained stability for 1.2 hours, preventing vapor ignition, avoiding $800,000 in equipment damage, fuel truck fire loss, and airport closure costs, complying with airport safety regulations.
3. Ultra-Cold Aviation Gasoline Leak (Small Airport, Canada, -14℃)
A 530m² aviation gasoline leak happened at a small northern airport ground support fuel depot during a cold snap (-14℃), caused by a frozen temporary tank valve. The leak mixed with frost and tarmac dust, forming a flammable slurry, and wind chills (-22℃) hindered control. Technicians deployed FP 6% (-20℃) via heated corrosion-resistant foam generators:
Its -20℃ freezing point prevented solidification (standard foam hardens at -10℃), and low viscosity flowed through insulated corrosion-resistant hoses, covering the leak in 40 seconds.
The 7.1±1 expansion ratio created an insulated, corrosion-resistant foam blanket, preventing vapor ignition and slowing ice formation for 107 minutes. Crews repaired the valve safely, avoiding $740,000 in emergency costs and regulatory penalties.
4. Why Standard Protein Foam Fails Here
| Airport Depot Challenge | Standard Foam Limitation | FP Series Solution |
|---|---|---|
| Cold Weather Solidification | Solidifies at ≥-10℃ (unusable in cold tarmac zones) | FP 6% (-20℃) stable in -15–-10℃ |
| Clogging in Corrosion-Resistant Gear | Viscosity >50 MPas blocks corrosion-resistant sprayers | ≤30 MPas viscosity, compatible with corrosion-resistant equipment |
| Tarmac Degradation | Foam breaks down quickly in tarmac conditions | Corrosion-resistant fluoroprotein formulation |
