Abstract

© 2019, Emerald Publishing Limited. Purpose: Schools are vulnerable to strong-magnitude earthquakes. The purpose of this study is to develop a seismic evacuation safety index (ESI) to assess school’s safety as a function of the following parameters: means of egress, disaster preparedness and disaster response. Moreover, the study aims to simulate and study an evacuation model to estimate evacuation time for a realistic understanding of the evacuation processes. Design/methodology/approach: The paper used a semi-quantitative risk assessment method in developing the ESI. This was used to evaluate schools and classify them according to their level of evacuation safety. To estimate the evacuation time of each school, cellular automata theory and static floor field were used. Findings: The paper provides primary school stakeholders important parameters that they should consider in preparing pre-disaster plans to ensure safe evacuation of school children. Research limitations/implications: ESI focuses only on the means of egress, disaster preparedness and disaster response as the contributing factors. The structural conditions of each school building and assessment of non-structural elements are not considered. Practical implications: The ESI and the evacuation model can be used as a basis for evacuation planning and decision-making. This can help building owners and administrators in strengthening their disaster risk management plan by enforcing mitigating measures. Originality/value: ESI is an original idea and fills the gap regarding the safe evacuation of school children especially during a major seismic event.
