Dongfeng KR Fire Extinguisher Foam Dry Powder Fire Fighting Truck Application:
The Dongfeng KR Foam Dry Powder Fire Fighting Truck is a specialized vehicle designed to handle complex and high-risk fire emergencies by utilizing a combination of extinguishing agents.
Its application areas and the types of fires it is designed to combat include:
1. Primary Application Areas
The combined fire-fighting agents (foam and dry powder) make the truck ideal for large, specialized, and high-risk environments where water alone is insufficient:
- Petrochemical and Oil & Gas Facilities: Refineries, chemical plants, oil depots, petroleum storage facilities, and gas processing areas.
- Industrial and Manufacturing Sites: Large factories, industrial parks, and areas that handle various flammable materials.
- Ports and Docks: Facilities dealing with the loading, unloading, and storage of flammable cargo and fuels.
- Airport and Aircraft Hangars: Used for rapid intervention and tackling fuel-related aircraft fires.
- Municipal and Public Security Fire Brigades: For extinguishing large-scale oil fires and general material fires in cities and high-risk zones.
2. Types of Fires It Is Designed to Combat (Fire Classes)
The combination of foam and dry powder provides versatility across multiple fire classes:
Dry Powder Agent is effective on:
- Class B Fires: Flammable liquids (e.g., gasoline, oil, paint, diesel, solvents). Dry powder suppresses these fires by interrupting the chemical chain reaction.
- Class C Fires: Flammable gases (e.g., propane, butane, natural gas) and fires involving energized electrical equipment.
- Class D Fires (with specialized powder): Combustible metals (e.g., magnesium, potassium, sodium, aluminum).
- Class A Fires (with multi-purpose dry powder): Ordinary combustibles (e.g., wood, paper, textiles).
Foam Agent is effective on:
- Class A Fires: Ordinary combustibles (e.g., wood, paper). Foam provides a cooling effect and smothers the fire.
- Class B Fires: Flammable liquids (hydrocarbon and polar solvent types). Foam works by forming a blanket over the liquid surface, smothering the fire, and preventing the release of flammable vapors.
