Mobile foam unit is a portable firefighting system designed to store, mix, and discharge firefighting foam for extinguishing flammable liquid (Class B) fires or suppressing hazardous material incidents. Unlike fixed foam systems (e.g., foam chambers or fixed pourers), mobile units are self-contained, transportable, and deployed flexibly to emergencies. They are critical in scenarios where fixed systems are absent, impractical, or insufficient, such as wildfires, industrial spills, aviation accidents, or remote storage facilities.
- Foam Concentrate Storage Tank: Holds foam concentrate (e.g., AFFF, AR-AFFF, or fluorine-free foam).
- In-line Inductor: Accurately mixes foam concentrate with water at the required ratio (e.g., 1%, 3%, or 6%).
- Water Supply Connection: Connects to hydrants, water tanks, or pumps.
- Hoses and Nozzles: Deliver foam to the fire (e.g., adjustable nozzles, foam cannons, or monitors).
- Mobility Platform: Mounted on a trailer, truck, skid, or cart for rapid deployment.
- Water Intake: The unit draws water from a hydrant, tank, or natural source.
- Foam Proportioning: The In line inductor injects foam concentrate into the water stream at a preset ratio (e.g., 3% for hydrocarbon fires).
- Mixing: Water and foam concentrate combine to form a foam solution.
- Aspiration: The nozzle or monitor aerates the solution, creating finished foam (low, medium, or high expansion).
- Application: Foam is discharged onto the fire to smother flames, cool fuels, and suppress vapors.
- Flexibility: Deployable to multiple locations without fixed infrastructure.
- Rapid Response: Critical for containing fires before they escalate.
- Scalability: Adjust foam type, expansion ratio, and discharge rate for specific hazards.
- Cost-Effective: Avoids the expense of permanent installations.
- Environmental Protection: Prevents fuel spills from igniting or contaminating ecosystems.
Mobile foam units are versatile and used in:
- Industrial Facilities:1. Extinguish spills or fires in refineries, chemical plants, or fuel storage areas. 2. Protect equipment like transformers or machinery.
- Aviation:Deployed as aircraft rescue and firefighting (ARFF) vehicles at airports.
- Marine:Combat shipboard fires or offshore platform incidents.
- Wildland Firefighting:Suppress wildfires involving flammable liquids or structures.
- Emergency Response:Handle highway tanker spills, railcar accidents, or hazardous material leaks.
- Military:Used in combat zones or fuel depot protection.
