Oxford cloth for fire-fighting clothing Fire-fighting clothing is one of the most important equipment to protect the personal safety of firemen in the first line of fire. It is not only an indispensable necessity for fire rescue sites, but also a fireproof device to protect firemen from harm.Therefore, it is particularly important to adapt to fire scene rescue activities. Chinese Name: fire-fighting clothing Foreign name: Firesuit Action: Fire Prevention Application area: fire fighting Current situation analysis The fire fighting clothing develops with the changes of the times.From 2013, the clothes of firemen can be roughly divided into two categories: one is the upper and lower parts, the other is the upper and lower parts (tops and trousers). Firefighting clothing is an important tool for firefighters to protect their bodies during fire activities.Therefore, it must possess the following characteristics: (1) from the perspective of protection, we must have fire resistance, heat resistance and heat insulation, and also have strong toughness to prevent sharp objects from colliding and colliding.In addition, it also has the ability to prevent chemicals from damaging the skin. (2) adapt to changes in environment such as cold and warm, wind and rain, and so on, can maintain physical strength and vigorous energy. 3. From the point of view of operational efficiency, fire-fighting clothing should have some leeway in the operation, try to choose materials with good elasticity and good quality, and also should carefully study the texture, shape and structure of the materials. (4) considering the safety management and the overall planning of the army, the upper and lower levels should be effective to ensure that the fire fighting clothing plays its due role. The advantages of the upper and lower parts of the fire suit are: high safety (including lower body protection, high systemic protection), easy movement, easy to wet, good waterproof, cold resistance, good function and appearance.Disadvantages are: poor heat dissipation, body heat is not easy to discharge, high cost, clothing weight. The advantages of the upper and lower joint type fire-fighting clothing are: high heat dissipation, easy discharge of body heat and low cost.The disadvantages are: poor safety, inconvenient activities and body weight. Terminology definition The following terms and definitions apply to this standard: 3.1 fire fighting protective clothing Protectiveclothingforfirefighters A special clothing worn by firemen during fire fighting is used for thermal protection of their upper and lower torso, head and neck, arms and legs, but the protective range of protective clothing does not include head, hands and feet. 3.2 waterproof breathable layer moisturebarrier A protective clothing part used to prevent water from infiltrating into the thermal insulation layer while discharging water vapor. 3.3 insulation layer Thermalbarrier Protective clothing part used to provide heat insulation protection. 3.4 seam seam FabricThe two edge connections are securely attached to protective clothing by sewing or other means. 3.5 reflective marking tape reflectivetrim The fabric that sew on the coat can reflect light as a mark is helpful to improve visibility. 4 styles, sizes and specifications 4.1 the style of this standard protective clothing is divided into two parts, which are made up of protective coat and protective trousers. The conjoined protective clothing can also refer to the performance requirements of this standard. Model 4.2 is set according to GB/T1335.1 and GB/T1335.2 regulations. 4.3 specifications The main specifications of protective clothing are designed according to the relevant regulations of GB/T1335.1 and GB/T1335.2. The allowable deviation of the main parts of protective clothing is specified in Table 1.Table 1 the allowable deviation of main parts and specifications is cm Development trend With the change of urban structure, high-rise, deep and large buildings Fire-fighting clothing Fire-fighting clothing With the development of the highly intelligent society and the appearance of amazing technological innovations, the causes of fire have been complicated and diversified.Under such a complicated situation, the fire fighting clothing used for personal equipment of fire should also be divided into different forms. A, corresponding to the old wooden and fire-resistant so-called general residential fires. B, fire-fighting clothing corresponding to building fires with heat and smoke centered structures. C, the activity centered fire service on behalf of the special rescue team. D, firefighting clothing corresponding to all kinds of disasters such as virulent drugs. E, in addition to the above, the winter clothing and summer clothing and other seasons corresponding to the fire suit. In the future, taking into account all the above situations, it is necessary to adopt fire services that conform to the geographical conditions and forms of disasters and conform to the ISO specifications.
