Q: What Establishes It as a Reliable Fire Protection for Gasoline/Diesel Fires in Distribution Hubs?

Onshore product oil distribution stations-critical hubs for storing, transferring, and dispatching finished oil products (gasoline, diesel, and kerosene) to gas stations and industrial users-face unique Class B hydrocarbon fire risks. These risks stem from frequent tank truck loading/unloading, small-batch storage tank overflows, pipeline joint leaks, and accidental spills during manual operations. Unlike large refineries or tank terminals, distribution stations feature compact layouts with dense small-volume tanks (50–500m³), narrow operation aisles, and mobile refueling equipment, operating across diverse temperature zones: ambient loading/unloading yards (15–32℃), low-temperature small-batch storage (-5–10℃), and ultra-cold emergency reserve tanks (-15–20℃) in northern cold regions. Standard protein foam concentrates often struggle in these scenarios: they solidify above -10℃ (unusable in winter), have high viscosity (>50 MPas) that clogs small-diameter foam nozzles and mobile foam equipment, and lack the rapid coverage capability needed for compact, crowded layouts. The FP Series Fluoroprotein Foam Concentrate (FP 3% (-16℃) and FP 6% (-20℃)) addresses these pain points with low-freezing-point formulations, low viscosity, and efficient foam expansion, while complying with NFPA 11 and GB 15308 (Chinese National Standard for Foam Concentrates) to meet global and regional safety requirements.

2. Ambient Loading Yard Gasoline Spill (East China Distribution Station, 29℃)

A 1,200m² gasoline spill occurred during a tank truck loading operation at an onshore distribution station, caused by a loose coupling on the loading arm. Crews deployed FP 3% (-16℃) via portable foam sprayers and small-diameter hoses:

Its ≤30 MPas viscosity ensured unobstructed flow through 50m of 50mm-diameter hoses, even in narrow aisles between storage tanks, reaching the spill in 45 seconds-30% faster than standard protein foam.

The 6.8±1 expansion ratio created a dense, uniform foam blanket that covered the entire spill in 2 minutes, with 5.7-minute 25% drainage time maintaining stability for over 1 hour. This prevented fire ignition near the idling tank truck engine and avoided $1.2M in tank damage, product loss, and station shutdown costs, complying with GB 15308 and local fire safety regulations.

3. Ultra-Cold Emergency Reserve Diesel Leak (Northeast China Distribution Station, -19℃)

A 900m² diesel leak occurred in an ultra-cold emergency reserve tank (-19℃) due to a frozen tank seal failure during a winter cold snap. Technicians deployed FP 6% (-20℃) via fixed foam injection systems and mobile foam generators:

Its -20℃ freezing point prevented solidification (standard protein foam would harden at -10℃, rendering it unusable), and the low-viscosity formula ensured smooth flow through frozen pipelines, covering the leak in 55 seconds.

The foam blanket maintained integrity for 120 minutes, resisting wind chills of -26℃ and preventing diesel vapor ignition. This allowed crews to thaw and repair the tank seal without fire incidents, avoiding $850,000 in emergency response costs and supply chain disruptions to nearby gas stations.
