As enclosed or semi-enclosed spatial structures, tunnels, once a fire occurs, experience rapid spread, high smoke concentration, and significant evacuation difficulties, posing a substantial threat to personnel safety and the transportation infrastructure itself. Therefore, adopting efficient fire prevention measures, such as applying fire-retardant coatings, has become an important means of improving the fire resistance of tunnels. Fire-retardant coatings not only effectively isolate heat transfer and slow the spread of fire, but also form a protective layer in the early stages of a fire, buying valuable time for escape and rescue. However, many poorly ventilated areas exist during the application of fire-retardant coatings in tunnels, necessitating monitoring of the tunnel installation environment to prevent harmful environmental factors from affecting construction workers.
