Summary: This study examines the effect of heat and moisture transfer on steam burn in a coupled thermal hazardous environment. A coupled model on heat and moisture transfer is proposed and validated through experiments. The model accurately predicts the skin temperature and steam burn in the coupled thermal environment. The primary cause of skin burn in dry heat exposure is radiant heat transfer, while the existence of hot steam reduces radiant and conductive heat transfer. In wet heat exposure, the primary cause of skin burn is moisture phase change on the skin surface.

Summary: Process operators play a crucial role in monitoring the petrochemical industry. They are often the first responders and take measures to mitigate the effects of process disruptions and incidents. Personal protective equipment is necessary as operators may be exposed to dangerous circumstances, such as high heat radiation levels during fires. This study investigated the protective clothing of operators by exposing professional firefighters to different heat radiation levels. The experiments showed that operators can be safely exposed to certain levels of heat radiation for a specific time period.

Summary: This study investigates the impact of fabric deformation on both thermal protective and thermal hazardous performance. The results show that increasing tensile ratios decrease heat storage in the fabric system but increase the skin absorbed energy. Tensile ratios have a more negative effect on the thermal protective performance of single-layer fabric than double-layer fabric. Compression significantly improves heat discharge to the skin. Regression models demonstrate that fabric deformation has a greater effect on thermal hazardous performance, particularly compression.

Summary: The effect of the number of layers of the thermal liner on the thermal protection properties of thermal protective clothing has been studied. The experiment shows that the protection time increases with the increase in the number of layers, and decreases with increased heat flux. The effect of the number of layers is more prominent at a lower level of heat flux.

Summary: This study proposes a new method to optimize the protection and comfort properties of multilayer fabric systems in thermal protective clothing by applying honeycomb structures. Research found that honeycomb sandwich structure fabric systems are lighter and more comfortable to wear than traditional fabric systems, with core thickness playing a dominant role in thermal protective performance. Additionally, increasing wall thickness and decreasing side length can improve the thermal protection performance of honeycomb sandwich structure fabric systems.

Summary: Developing ceramic nanofibrous membranes for the thermal insulation layer of firefighting protective clothing is crucial. Previous membranes were brittle and lacked elastic and compressible properties. This study successfully fabricated elastic and compressible Al2O3/ZrO2/La2O3 nanofibrous membranes, which maintained excellent performance in a wide range of temperatures. These membranes have low thermal conductivity and high working temperatures, making them promising for thermal insulation in firefighting protective clothing.
