We believe everyone knows that fire trucks are used for fire fighting and disaster relief, but in many countries, fire trucks are also used for other emergency tasks. In reality, disaster relief is complicated on the spot, and independent types of fire trucks cannot perform all daily tasks. Therefore, a variety of matching application plans for multi-type fire trucks emerge from time to time.
The first and most basic contemporary fire trucks are basically equipped with steel ladders, high-pressure water guns, hand-held fire extinguishers, self-contained breathing apparatus, protective clothing, demolition tools, special rescue tools, etc. Some of them will also be equipped with water storage tanks and centrifugal pumps. , foam plastic fire-fighting equipment and other large and medium-sized automatic fire-extinguishing devices.
For conventional fires, water storage tank type fire trucks can be used for fire fighting according to large space water storage tanks and high-pressure water pumps or fire water cannons. However, with the continuous development of high-tech, only water is used as fire fighting raw materials for fire fighting. Equipment is clearly not enough.
Chemical processing plants should not be extinguished with water, but should be covered with sand; skyscrapers cannot be extinguished with only water storage tank-type fire trucks, so they have ladder fire trucks; fire accidents involving aircraft accidents are also equipped with professional airports Rescue fire trucks; for fires in precious machinery and equipment, instruments, key antiquities, books and archives, etc., it is necessary to be more technical and professional.
1. Quickly put out fires in urban areas
Use fire hydrants to put out fire quickly – pump fire truck
Relatively simple types of fire trucks are mostly used for fire fighting in urban areas. When applied, they must be matched with on-site fire hydrants or water absorbing water for fire fighting. They can also be used as tower-less water supply equipment vehicles for other fire trucks.
Store and move water resources to quickly put out fire – water storage tank fire truck
It is an essential fire fighting vehicle for the fire brigade and post fire brigade of the public security organs. Because the vehicle is equipped with separate water resources, it can carry out simple and separate daily fire fighting tasks in areas with little water, and it can be used as a tower-free water supply equipment and transportation equipment at the fire scene. Water line trip.
2. Quick rescue at the unique fire scene
Flammable liquid quickly extinguishes fire – foam plastic fire truck
Foam plastic fire truck is a necessary fire fighting vehicle for technical professional fire brigade in big cities. It is suitable for extinguishing flammable and flammable liquid fire accidents. It is very suitable for extinguishing crude oil fire accidents. It is used in petrochemical equipment companies, oil pipeline ports, and airports. Fire truck is required.
It achieves fire fighting effect according to the excellent technological performance of foam plastic. (foamed plastics have low density, good fluidity, strong continuity, strong burning resistance, poor heat transfer, and high adhesion. Foamed plastics can be sprayed during firefighting to quickly cover the burning objects. According to the barrier of flammable vapor, The transmission of gas and calorific value to achieve the purpose of fire fighting)
Non-aqueous liquid quickly extinguishes fire – high-expansion foam fire truck
With the rapid development of economic development, firefighting technology is also being upgraded. High-rate foam firefighting is a new type of high-efficiency and low-cost firefighting technology. High rate foam is a kind of mechanical equipment gas foam, which has greatly improved fire fighting properties compared to low and medium rate foam. It uses large amount of polyurethane foam, excellent fire resistance, lower density and stronger fluidity for fire fighting. , and the same as the previous foam plastic fire truck, according to the closed function, steam function, water cooling function overlapping each other to achieve the purpose of fire fighting.
Reasonable and rapid fire extinguishing in areas where library pipes, historical museums, and high-precision machinery and equipment are located – CO2 fire trucks.
The collection of books in the library tube and the precious collections in the history museum are the spiritual wealth of people. In addition to immediately extinguishing fire accidents, it is necessary to maintain such objects as much as possible. In addition, there are also costs for making certain instruments and meters. If it is too high or the equipment has a key function, it must be prioritized to maintain them when the fire is extinguished.
Therefore, the past fire safety plans could not achieve the goal, and CO2 fire trucks should be born from time to time. Perhaps now CO2 fire extinguishers are all large-scale applications. Because liquid gas does not ignite and does not burn, it is non-conductive and non-corrosive. Time to digest and absorb a lot of heat, so as to achieve the purpose of rapid cooling. In addition, it is not easy to destroy objects other than burning materials. Many overflowing CO2 will dilute the water content of liquid oxygen, so as to achieve the purpose of immediate fire fighting.
Rapid firefighting of induction electrical equipment fire accidents – powder fire truck
This kind of fire truck is the supplementary fire fighting for the foam plastic fire truck, and the upgraded fire fighting for the flammable gas and induction generator equipment, and is suitable for large and medium-sized chemical pipeline fire accidents.
According to the use of the volatiles of organic matter in the powder to fight fire, layers of glassy soil layers can also be produced at high temperature, and then the oxygen barrier can be used to extinguish the fire. It is used in fire extinguishers on the same scale as CO2, and it is one of the necessary fire extinguishers.
Different types of fire trucks are used in the rescue of fire accidents in different scenarios, and daily life is usually complicated. It is more reasonable and effective to match different fire trucks to carry out complicated rescue tasks.
