Despite improvements in textile fiber, fabric, and thermal protective clothing, burn injuries still occur in complex thermal environments. Thermal protective clothing is typically constructed of multilayers that consist of shell fabric, a moisture barrier, and a thermal liner. These multilayers and the air spaces between them decrease the heat transfer from thermal hazards to the skin and prevent burn injuries. However, during thermal exposure, these protective clothing layers can store a large amount of thermal energy and can discharge that energy naturally or by force (sudden compression) during cooling periods, contributing to burn injuries.

尽管在纺织纤维、织物和热防护服方面有所改进，但在复杂的热环境中仍然会发生烧伤。热防护服通常由多层构成，所述多层包括面料、防潮层和热衬里。这些多层膜和它们之间的空气空间减少了从热危害到皮肤的热传递，并防止烧伤。然而，在热暴露期间，这些防护服层可以储存大量的热能，并且可以在冷却期间自然地或通过强制（突然压缩）释放该能量，从而导致烧伤。
