description The invention relates to the technical field of life-saving equipment, in particular to a fire-fighting respiratory protection system suitable for a fire scene and rescue equipment. The fire-fighting respiratory protection system suitable for the fire scene comprises an expiration pipe, an inspiration pipe, an absorption device, a breathing air bag, an oxygen generator, a cooling device and a controller. The absorption device is communicated with the expiration pipe and suitable for absorbing carbon dioxide, and the breathing air bag is communicated with the absorption device. The oxygen generator is a chemical oxygen generator. An inlet of the cooling device communicates with the breathing air bag, and an outlet of the cooling device communicates with the air suction pipe. Nitrogen and part of oxygen in exhaled gas are recycled and supplied to a user, a system isolated from the outside is formed, and the high-pressure physical explosion risk and the chemical explosion risk in the high-heat environment existi
