How to use Isuzu 4000 liters foam fire fighting truck-fire-trucks.com

Isuzu 4,000L foam firefighting truck is engineered to combat Class B fires involving flammable liquids (e.g., petroleum, chemicals). Its foam projection system mixes water with fire-suppressing foam at precise ratios, forming an oxygen-blocking blanket to rapidly extinguish liquid fuel blazes. Equipped with a high-capacity 4,000-liter tank and a high-pressure pump, Isuzu 4,000L foam firefighting truck delivers sustained foam discharge rates up to 4,000 L/min, enabling swift control of expansive fire incidents. Its extended-range monitor nozzle projects foam over 60 meters, ensuring operator safety during refinery, warehouse, or wildfire emergencies.

Operational Guide for Isuzu 4,000L Foam Firefighting Truck: Technical Parameters and Procedures

1. Vehicle Overview
The Isuzu 4,000L foam firefighting truck is engineered for rapid response to Class B (flammable liquids) and Class A (solid combustibles) fires. Built on a heavy-duty Isuzu FVR chassis, it features a 6HK1-TCG61 diesel engine with a power output of 176 kW (240 hp) at 2,200 rpm, generating 981 N·m torque. The chassis complies with Euro V emission standards and includes a 9-speed manual transmission for optimal off-road maneuverability.

2. Firefighting System Specifications

Water Tank: 4,000-liter capacity, constructed from corrosion-resistant 304 stainless steel with internal baffles for stability.
Foam Tank: 500-liter polyethylene tank, compatible with AFFF (Aqueous Film-Forming Foam) or AR-AFFF (Alcohol-Resistant) concentrates.
Proportioning System: Electronically controlled foam induction system with adjustable ratio (1–10%) via a rotary dial on the pump panel.
Pump Unit: Mid-ship-mounted centrifugal pump (Model NH30), delivering 4,000 L/min at 1.0 MPa pressure. Maximum suction lift: 7 meters.

3. Discharge Equipment

Roof-Mounted Monitor: Remote-controlled telescopic monitor with 360° rotation, 70-meter range (water), and 55-meter range (foam). Flow rate adjustable from 100–3,800 L/min.
Handline Reels: Two 30-meter Class B rubber-lined hoses (Φ65 mm) with adjustable fog/straight stream nozzles (500 L/min max).
Rear Bumper Reel: 20-meter high-pressure hose (Φ25 mm) for auxiliary operations (200 L/min).

4. Control and Monitoring Systems

Pump Panel: Centralized interface with analog pressure gauges, tachometer, and digital foam ratio display. Includes manual override for pump RPM (0–2,500).
Cabin Display: 7-inch LCD screen for real-time monitoring of water/foam levels, pump status, and engine diagnostics.
Lighting: Four 500W LED floodlights (360° rotation), two rear warning beacons, and scene lighting compliant with NFPA 1901 standards.

5. Operational Procedure
Step 1: Pre-Deployment Checks

Verify water/foam tank levels and inspect hose integrity.
Ensure pump priming valve is closed and suction strainer unobstructed.

Step 2: Engine and Pump Activation

Start the chassis engine; engage PTO (Power Take-Off) to activate the pump.
Gradually increase engine RPM to achieve 0.8 MPa operating pressure.

Step 3: Foam Application

Select foam ratio (3% for hydrocarbons, 6% for polar solvents).
Open foam tank valve; confirm ratio via panel indicator.

Step 4: Discharge Control

For roof monitor: Use joystick to adjust elevation (‑15° to +75°) and flow rate.
For handlines: Gradually open nozzle valves to prevent pressure surges.

Step 5: Post-Operation

Flush system with clean water for 10 minutes to remove foam residue.
Disengage PTO; record operational data in maintenance log.

6. Safety Protocols

Maintain 5-meter clearance from flames during monitor operation.
Avoid pump cavitation by ensuring suction lift ≤7 meters.
Annual hydrostatic testing of tanks and NFPA-certified pump inspections mandatory.
