The appearance of firefighter's clothing after flame engulfment was also analyzed. The analysis indicated that the more integrity the inner layer of clothing had after exposure, without brittleness and shrinkage, the more protection the clothing was. At the same time, the accessories on the firefighter's clothing were also crucial, especially for membrane and retro-reflective stripes. If they shrink in the exposure of flame, the protection of the clothing would reduce.

由检验各消防衣的外观来分析，则可知如果使用的材料在进行火焰冲击时，能够使防护衣仍具有完整的结构，且不产生脆化与收缩，则愈具有防护能力；同时对於消防衣上的零配件也要格外注意，尤其是薄膜与反光条，若此处产生热收缩，就会减低消防衣的防护能力。
