To explore different operators' eye movement indexes which can reflect the degree of fire hazard identification in university laboratories, the experiments were carried out in 60 undergraduate students, and these students were divided into 4 groups based on their gender and experimental experience. Taking the panorama of laboratories as stimulus materials, the Tobii X2 -30 eye tracker was used to carry out eye movement measurements, and the data of eye movement were analyzed by using the single-factor multivariate variance analysis and multiple comparison method. The results show that different gender has little influence on fire hazard identification in laboratories; the attention rate and sensitivity of fire hazard in experienced operators are 21.62% higher than that in inexperienced operators; in the five types of fire hazards, the subjects spent more time in aging circuit, which reached 22.13%. And the time spent in combustibles piled up randomly has the lowest percentage, only 17.90%. The data of fixation point count, blink count, average blink time and average pupil diameter has no significant difference. The different experimental experience levels of the subjects have significant influence on the eye movement results. The gaze trajectory of experienced subjects is hierarchical and logical. For inexperienced subjects, the trajectory is on the same horizontal line; what's more, both the back view and the saccade are multiple. Therefore, according to operator's professional experience level, the countermeasures for fire safety education and management in laboratory are put forward. These results can guide the fire safety management effectively in university laboratories.
