What is the significance of the existence of the Burning dummy system?

In a fire hazard environment, people need to wear thermal protective clothing to avoid fire damage. Thermal protective clothing is widely used to protect firefighters, steel workers and other staff working in high temperature hazardous locations. With the increase of clothing exposure time in the flame, the surface temperature of the clothing will gradually increase due to the direct burning of the flame, and a large amount of heat transfer causes the air layer under the clothing and the surface temperature of the human body to increase at the same time. Under the fire of the clothing, not only the thermal physical properties of the fabric itself will change and affect its thermal protection performance, but also after leaving the flash fire environment, the surface temperature of the clothing will still remain in a high range, and it will be different from the clothing under the clothing. And the temperature of the surface of the human body forms a temperature difference, and the continuous heat transfer causes the surface temperature of the human body to continue to rise. Studies have shown that burns may occur after the flash fire, and the energy stored in the fabric is also an important factor in predicting burns. Therefore, even if the thermal protective clothing can resist the burning of the flame for a short time, the clothing can still cause burns during the cooling process. Therefore, it is particularly important to study the temperature changes of clothing and human body after burning.

The research on multi-layer protective clothing using TPP instrument (thermal protection performance tester) shows that the outermost fabric has an important influence on the protective performance of multi-layer protective clothing. Experiments were carried out with TPP instruments, and it was found that prolonged exposure to a heat source with low heat flux was more likely to cause burns than short periods of intense burning. In the actual wearing process, the thermal protection performance of clothing not only depends on the performance of the fabric itself, but also needs to be comprehensively considered from the aspects of clothing style design, specifications and dressing posture. The Burning dummy system's test method shows advantages in order to simulate the human body in an actual fire situation as realistically as possible and to measure the surface temperature of clothing and the human body safely and accurately.
Burning dummy system
Use an infrared thermal imager to monitor the temperature change of the clothing surface in the Burning dummy system dressing test, use the sensor on the body surface of the Burning dummy system to reflect the temperature change of the skin surface, and analyze the flash fire time, clothing material and size, and the state of clothing posture on the surface. The effect of temperature changes. Burning dummy system tests the above parameters in order to provide reference for the design and development of thermal protective clothing.
