The primary goal of emergency evacuation for pedestrians is evacuating as many people as possible to safe areas in a shortest time when the accident occurred. And the primary factor of pedestrian evacuation is egress. According to the literature, we can know that the reasonable design of the evacuation corridor and the right guidance to pedestrians are very important, and analyzed main affect factors to the evacuation corridor, which affect of the evacuation speed for corridor at different pedestrian flows intensity, the width of evacuation corridor, setting canalization to corridor and the size of space of corridor peripheral. This paper use VISSIM simulation software to study on pedestrian flows evacuation. So the formulation for pedestrian evacuation program should consider a variety of elements for the design of the evacuation egress and corridors to increase efficiency and reliability for pedestrian evacuation.

Emergency evacuation is an important issue in fire safety. In this study, a cellular automaton (CA) model in which the human behaviour termed ‘flow with the stream’ is considered is proposed to simulate the procedure of emergency evacuation. Based on the CA model, the influence of the number of guiders to the evacuation from a large compartment is analyzed through numerical test. The result shows that the proposed CA model is a promising tool that may be used in fire safety design.

The fire accident is a substantial risk in the subway due to the complexity of the underground construction confined space, which can cause a large number of human fatalities. Therefore, some effort should be made to promote the public security in subway fire accidents. Among of them, the establishment of emergency evacuation plan is very important in fire safety design and should be paid enough attention because it can provide beneficial help to life safety. The evacuation strategy including the evacuation route and evacuation safety zone are detailedly discussed in this paper, which lays the foundation for future studies of safe evacuation in the subway fire accidents.

Focus on the technology and requirements of nozzle in fire engine to optimize the ability of blasting of nozzle, this paper built the model of fluid in nozzle, and simulation studied based on Fluent. This paper analysis the stage of nozzle, contraction angle, size of entrance and slenderness ratio as the influencing factors, supplied the reliable theoretical foundation for the design and structural improvement of nozzle in fire engine.

Purpose The purpose of this paper is to present the findings of a theoretical calculation for the emergency evacuation of an auditorium facility managed by a university in Saudi Arabia. Design/methodology/approach The authors reviewed the published literature to identify the sources of fire incidence, guidelines for means of escape in assembly occupancies and human behavior in fire emergencies. The theoretical method of the SFPE handbook to estimate the required evacuation time was subsequently applied to a case study of an auditorium facility managed by a university located in Saudi Arabia. Finally, the authors developed recommendations for the performance-based fire safety evacuation of the auditorium facility under review. Findings The study showed that a total of 6 minutes 39 seconds is needed to evacuate the whole auditorium. However, reviewed literature for assembly occupancies requires between 4 minutes 30 seconds and 6 minutes 24 seconds for total evacuation. Though, the calculated evacuation time is close to generally acceptable limits. It was noted that overcrowding and bottlenecks may be formed in some of the exit routes. Originality/value This paper will stimulate and increase research and industry concern for performance-based design of assembly-type facilities. This will be of significant value to designers, engineers, facilities managers, and owners in ensuring the safety of occupants in assembly-type facilities.
