You have to know the three major properties of fire insulation clothing

Fire-fighting thermal insulation clothing is a kind of thermal protection clothing developed for firefighters in high temperature working environment. Wearing this clothing can effectively protect firefighters from being burned by extreme heat, flame and steam when approaching the heat source. The embodiment of this protection advantage is closely related to the performance of the fire protection suit itself. Next, Hongan Fire Protection will reveal the three major properties of fire protection suits for you.

First, the thermal insulation performance. In actual use, most users of fire insulation clothing do not directly contact the flame, but the external heat is transferred to the human body in the form of heat convection, heat radiation and heat conduction, causing damage to the human body. Therefore, the thermal insulation clothing must have good performance of slowing down and preventing heat transfer, avoiding the harm caused by the heat source to the human body, and providing good safety protection for firefighters working in a high temperature environment. This is not only related to the thermal conductivity of the fiber raw materials of thermal insulation clothing, but also has a great relationship with the design of clothing, clothing fabrics and lining structure.

Second, flame retardant properties. In fires, the most serious burns often occur in the parts where people's clothes are on fire, so the flame retardant performance of fire protection clothing is very important. During the use of thermal insulation clothing, the outer side is generally in direct contact with the flame, while the inner side is rarely in contact with the flame. This requires the thermal protection fabric to have the ability to resist the flame from burning through from one side to the other side. Therefore, it is also necessary to consider the effect of the fabric on the flame. scorchability.

Third, heat resistance. The temperature in the fire environment may rise to 600 degrees in a few minutes, and even in the room where the fire is directly on fire, the temperature is about 300 degrees, and the high temperature that can melt plastic is enough to kill people. Fire insulation clothing is mainly used for high temperature operations, and must maintain its own physical properties at high temperatures without shrinking, melting and brittle carbonization.

It is precisely because of these three properties of the fire protection suit that it can protect the human body from the thermal damage of the flame. In addition, its heat and moisture transfer ability is also more conducive to the evaporation of sweat and heat loss of the human body, satisfying the needs of firefighters. The use requirements of high temperature operation ensure the personal safety of firefighters in special environments.
