Abstract
Through reviewing a large quantity of relevant literature and investigating into a few representative fire cases, some typical preevacuation
human behavior under fire situations are discussed and defined preliminary. Furthermore, interactional factors that influence
human reactions before evacuation in fires are demonstrated systematically. On the basis of this theory, attribution analysis is also
conducted on psychological process to fires of human in pre-evacuation time, which includes the first phase of risk perception and the
second one of decision-making, while combining the effects from psychological deviation and culture background. Moreover, a
probabilistic description method of pre-evacuation human behavior concerning psychological process in fires is proposed in this paper for
an exploration. The results may assist in completing the theory of human psychological reactions and emergency behaviors in preevacuation
time of fire situations, and also providing scientific reference for those coping with unconventional emergencies and
developing the measures of intervention.
