FBH-L/A firefighter entry clothing is a protective suit worn by firefighters when they pass through a fire area for a short period of time or enter a fire scene for firefighting and rescue operations. The suit is mainly composed of seven layers of materials, including double-layer adiabatic high silica glass fiber (with a fire resistance limit of 1700 degrees), fire-resistant fiber cloth, fire-resistant carbon fiber felt, heat insulation and fireproof layer, heat insulation layer, and comfort layer, with good fire resistance and heat insulation performance. This suit is not only a personal protective equipment for firefighters during firefighting operations in the flame zone, but also can be used for the personal protection of workers in high temperature repair of kilns in industries such as glass, cement, and ceramics.
