Foam fire truck (also known as foam fire truck) is a professional fire-fighting equipment designed for specific fire types. Its core role is to achieve efficient and targeted fire extinguishing through foam extinguishing agent. Its main functions and application scenarios are as follows:
1、 Core fire extinguishing function of foam special fire truck
Extinguish flammable liquid fires
Specially designed for extinguishing fires involving petroleum, petrochemical products, flammable liquids (such as oils, alcohols), and organic solvents. The foam covers the surface of the combustor, insulates the oxygen, cools down, and quickly suppresses the fire.
Double extinguishing mechanism covers suffocation: the foam layer blocks the contact between air and fuel.
Cooling and flame retardant: Water evaporates and absorbs heat, reducing the temperature of combustibles.
2、 Special types and enhanced functions of foam special fire truck
Compressed air foam system (CAFS)
Through accurate mixing of air and foam liquid, a more stable and strong adhesive foam can be generated, which saves water, saves foam and has strong penetration, especially suitable for petrochemical and power facility fires.
Liquid nitrogen combined with foam
Add liquid nitrogen to enhance the stability and coverage effect of foam. At the same time, nitrogen suffocates the fire source, reducing the temperature more significantly, and improving the fire extinguishing efficiency by about 70% 9.
Dry powder foam combination
Combined with the advantages of instant suppression of deflagration by dry powder and continuous coverage by foam, it is suitable for hazardous chemical fire and electrical equipment fire.
3、 Foam specific fire truck with auxiliary rescue and protection functions
Chemical accident disposal
Spray foam to form an isolation barrier to inhibit the volatilization or diffusion of toxic and harmful substances.
Rescue support
Provide firefighting equipment, life-saving devices, and emergency medical rescue tools to assist in personnel evacuation and first aid.
4、 Main application scenarios of foam special fire truck
Location: Petrochemical plants, oil depots, airports, ports, hazardous goods warehouses.
Fire types: oil tank fire, pipeline leakage fire, chemical fire, and enclosed space fire (such as cabin and warehouse).
5、 Maintenance and operational characteristics
Independent combat capability: with its own water tank, foam tank and fire pump, it can operate independently away from the water source.
High maneuverability: adaptable to urban roads and complex terrain in the wild, quickly responding to fire scenes.
Strict maintenance requirements: foam liquid state, pipeline tightness and nitrogen pressure shall be checked regularly to ensure the reliability of emergency state.
