19 The appearance quality shall be measured by visual inspection, and the result shall comply with the provisions of 5.11.
The special protective clothing worn by firefighters when they are close to the flame area and are exposed to strong radiant heat during fire fighting and rescue is used to insulate their upper and lower torsos, heads, hands and feet, including firefighting jackets, firefighting pants, firefighting hoods, firefighting gloves and fireproof foot covers.
The firefighting suit is composed of multiple layers of fabrics such as the outer layer, the heat insulation layer, and the comfort layer. The materials of this combination can be made into a single layer or multiple layers. The outer layer of the heat insulation suit should be made of a metal aluminum foil surface material that reflects radiant heat and can meet the basic clothing manufacturing process requirements and the performance requirements of the corresponding standards for auxiliary materials.
