Cooling vest to cool the firefighter's rescue

Fire suits are the most basic protective equipment when firefighters perform a fire extinguishing task. The new type of fire fighting suit adopts a four-layer structure and is a special protective equipment used exclusively for fire extinguishing. It does not apply to other rescue operations. The clothing also has no autumn clothing or winter clothing. The fire suits have the function of flame retardant and heat insulation, so they are also known as thermal insulation clothing. The cotton lining of fire service clothing is actually the heat insulation layer, and it is the most important protection layer to protect firefighters from heat burn. The split design is for easy cleaning and must be worn during the fire extinguishing operation.

How to solve the problem of high temperature inside the human body after wearing fire fighting clothing, the following summarizes the following aspects:

1. Adapt to new equipment, change dress habits, and actively explore new ways to carry firefighters. Old-style fire fighting uniforms generally require belts to be tied around the waist during fire fighting and rescue. This is a safety requirement for air operations. Another important reason is the carrying of equipment. The new type of fire protection clothing is more tightly guarded, and the internal heat dissipation mainly depends on the natural ventilation of the hem of the fire suit. The belt is precisely blocking this important channel. Abroad, when using special firefighting suits, it is rarely used outside the belt. It seems that we should change our dress habits in due course.

2. Professional equipment is specially used to properly reduce the continuous wearing time of firefighters wearing fire fighting clothing. The specialization of firefighting clothing is a must for fire protective clothing. Extinguishing protective clothing is a special protective equipment for fire extinguishing. It should not be worn during general emergency rescue. A special emergency rescue clothing standard is under development. If it is necessary to wear it, you can remove the heat insulation layer without entering the fire scene. . At the same time when performing outdoor firefighting and rescue missions, it may be considered to reduce continuous working hours, work for about 45 minutes, and it should be rotated for rest to reduce the chance of heat stroke.

3. Add some measures to prevent heatstroke. When the fire is extinguished in the fall of the South, simple protection measures can effectively prevent heat stroke. Underwear should be made of pure cotton fabrics that are comfortable to wear and have good sweat absorption. Do not wear synthetic underwear. Drinking some salt water and mung bean soup is also a good solution for summer heat.

4. Use high-performance fire service. It is the dream of every firefighter to reduce the weight and volume of clothing and reduce the thickness of insulation. In some developed regions in the world, the fire protection clothing they use is exactly the same as the structure of our clothing. However, the heat insulation layer is excellent, the weight is light, and the ventilation effect is good. It can also achieve a good protection effect, but the price is very expensive.

5. Take forced cooling measures. In some special situations, firefighters are required to work long hours under hot conditions. What to do at this time. There are ways to cool down the vest. The principle of the cooling vest is very simple. Put the energy storage bag in the vest into the refrigerator or ice water for a period of time before putting it to use. After being worn on the body, the low temperature of the energy storage bag is much lower than the human body and the ambient temperature. Provides users with low-temperature energy, thereby reducing the body's own temperature.

Fire fighting clothing is the personal protection equipment for each firefighter. It must be properly worn and used in order to protect our safety in firefighting and rescue operations.
