Fully understand the limitations of fire-fighting protective clothing

Firefighters are usually in the environment of high temperature and flame when extinguishing fire, so the heat insulation performance is a very important index in both foreign and Chinese fire protection clothing standards. However, unless new technologies and materials are developed by leaps and bounds, increasing protection usually means increasing the weight of suits, so fire-fighting protective clothing must give consideration to both protection and portability. It can be said that fire-fighting protective clothing is the armor of our firefighters, but it is up to scientists to improve their performance. Our task is to make good use of fire-fighting protective clothing and fully understand the limitations of fire-fighting protective clothing. There are three different stages in the performance of fire-fighting protective clothing. These three stages take place in a short time, aiming at protecting firefighters from flashover or afterburning. The first stage is flashover, in which the fire-fighting protective clothing is exposed to high temperature (possibly 800-1000°c) and absorbs a lot of heat. This heat absorption leads to the expansion and thickening of the fibers of fire-fighting protective clothing, which eliminates the conductive heat transfer and reduces the heat transfer to human body. In this process, the protection level of the outer fabric remains unchanged, so that firefighters can escape and stay away from heat. If firefighters encounter extreme fire phenomena such as flail and back burning, no matter what materials are used, it is important to evacuate the dangerous area as soon as possible, move to a safe place, and take off fire-fighting protective clothing (including jackets and trousers). The second stage is to escape. In the process of escape, the fire-fighting suit remains soft and flexible before cooling, providing extra critical protection for the wearer for several seconds. There is no crack at present. However, all fire suits (regardless of their structure) will continue to accumulate heat, so please take them out to avoid burns caused by the transfer of accumulated heat. The third stage is recovery. Firefighters take off their protective clothing to cool down and recover from the accident. Similarly, the fire-fighting protective clothing continues to cool gradually, releasing more waste heat.
