There will also be dangers in peacetime; in the symphony of fire and water, there is a mission that is eternal; there is an eye that always stares at the fire of life and death; there is a responsibility that is always firm in people's reputation: this is the sacred fire cause, Fearless fire officers and soldiers! Fire protection clothing is developed with the changes of the times.

There will also be dangers in peacetime; in the symphony of fire and water, there is a mission that is eternal; there is an eye that always stares at the fire of life and death; there is a responsibility that is always firm in people's reputation: this is the sacred fire cause, Fearless fire officers and soldiers!
Fire protection clothing is developed with the changes of the times. At present, firefighters' clothing can be roughly divided into two types: one is the upper and lower layers, and the other is the jacket and pants. Fire fighting clothing is an important tool used by firefighters to protect their bodies in fire fighting activities. The structure of fire protection clothing generally has the characteristics of high coverage, high locking and easy operation. Special protective work clothes such as spacesuits and diving suits are also equipped with corresponding equipment and devices.
Fire protection clothing must have the following characteristics:
1. It must have fire resistance, heat resistance and heat insulation, and also have strong toughness to prevent the impact and collision of sharp objects. In addition, it should also have the ability to prevent chemicals from harming the skin;
2, fire protection clothing in the operation of the activity space, try to choose the material with good telescopic performance, clothing texture, shape, structure and other aspects should also be carefully studied.
3. Adapt to changes in the external environment, such as cold and warm weather, wind and rain, and be able to maintain physical strength and vigorous energy;
4, heat insulation performance, when actually wearing fire protection clothing, most users do not directly contact the fire, but cause harm to the human body through heat conduction, convection and radiation heat transfer. Fire protection clothing must have good performance to prevent or slow down heat transfer, avoid harm to the human body, and provide good safety protection for users of thermal protection clothing working in high temperature environment.
5. The thermal insulation performance of fire protection clothing is related to the thermal conductivity of fiber materials, fabrics and clothing design. Also, the material and the structure of the material are important.
6, heat resistance, the fire can reach a high temperature of 600 degrees in a few minutes. Even in a room directly on fire, the temperature is around 300 degrees, and the heat that can melt the plastic can be fatal. Fire protection clothing is mainly used for high temperature operation. It must maintain its physical properties and not undergo brittle carbonization, shrinkage and melting at high temperatures.
Fire protection clothing not only has thermal protection performance, but also has good practical performance and wearing comfort. For example, it has certain tensile strength, abrasion resistance and tear strength, strong printing and dyeing, and strong washing resistance. It should also have a certain heat and moisture transfer capacity, which is conducive to the loss of human heat and the evaporation of sweat, and the physiological load capacity is low.
8. Comfortable to wear, fire protection clothing also needs to be light in weight, easy to wear, loose in structure, no restrictions on running, climbing, jumping and other actions, and not easy to cause hooking. Measures should be strengthened in the parts that are prone to injury to meet the requirements of coordination and comfort and improve work efficiency.
