Abstract: In order to explore the factors influencing the ability of firefighters to integrate the path in the process of indoor fire search and rescue in a non-visual environment, design experiments to simulate the dark indoor environment of the fire, analyze and compare the number of teams, the forward posture and the complexity of the spatial layout due to the influence of location, the best indoor rescue method is proposed to improve the safety and work efficiency of firefighters in the search and rescue process. The research results show that in a simple spatial layout, firefighters can complete indoor search and rescue tasks in a dark environment more safely and efficiently through teamwork and adopting an upright forward posture.

Key words: firefighter；non- vision, path integration, spatial perception, indoor search and rescue
