Flame-retardant protective clothing has always been an important piece of equipment for firefighters. During fire fighting and accident handling, firefighters have been sacrificed and injured due to thermal radiation, explosions, etc. Therefore, how to protect firefighters during fire rescue and what protective performance fire-retardant protective clothing should achieve. Selecting flame-retardant protective clothing with excellent performance has become an important topic in the field of fire extinguishing and rescue. Qualified flame-retardant protective clothing should meet the following performance requirements. Fire-fighting and flame-retardant protective clothing should have: heat insulation properties, flame-retardant and fire-retardant properties of the outer layer, waterproof and breathable properties, and reflective properties of reflective tapes.
Standard requirements for thermal insulation performance of protective clothing
my country uses the thermal protection capability TPP (thermal protective performance) value to characterize the thermal insulation performance of fire-fighting flame-retardant protective clothing. The principle is to evaluate the relative thermal protection capabilities of clothing by measuring the heat energy required to cause second-degree burns (burns) on the human body on the surface of the fabric. GA10-2002 stipulates that the TPP value of fire-fighting flame-retardant protective clothing should not be <8.
Fire-proof and flame-retardant performance requirements for outer material:
Fire-fighting and flame-retardant protective clothing is composed of an outer layer, a waterproof and breathable layer, an insulation layer and a comfort layer. The fire-fighting and flame-retardant protective clothing The outer layer of clothing is the layer that is in direct contact with fire and heat, and is also the most critical layer related to the quality of the product. Firefighters are generally exposed to high temperatures and flames when putting out fires. The permanent flame retardant performance of protective clothing is an important guarantee for the safety of firefighters. Comparison of hydrostatic pressure resistance and water vapor permeability requirements
The waterproof and breathable layer is a layer of protective clothing fabric that is used to prevent water from penetrating into the insulation layer while allowing water vapor to be discharged. This layer allows firefighters to extinguish fires Feel comfortable during combat to prevent other injuries from occurring.
Comparison of performance requirements for reflective tapes
The reflective marking tape should be tightly sewn on the top and trousers of the protective clothing. For split protective clothing, it should be at the bust, hem, cuffs and trouser legs of the top. The stitching width of the reflective marking tape should not be less than 50 mm, and the reflective marking tape should be visible in its 360° direction.
