Abstract

Aim: Despite the existence of established fire codes, the frequency of building fires in Sri Lanka has been on the rise in recent years. The primary objective of building codes is to ensure minimum acceptable fire safety standards in buildings, but deviations from the code can increase fire risk factors and exacerbate the severity of fires. This study aims to identify and rank such risk factors in three stages, beginning with design and concluding with maintenance.

Project and methods: The methodology of this research consists of a qualitative approach, which includes a literature review, a questionnaire-based survey, and semi-structured interviews with fire industry professionals. The questionnaire was developed in a Sri Lankan context following an extensive literature review that included the author's experience. The qualified and experienced panel of fire specialists was asked to rank the prepared questionnaire, which was summarized into twelve risk categories. Though there are few fire risk ranking methods, the relative importance index method was applied in this research as it is simple and easy to use for ranking the risk factors. The results obtained from the five-point Likert scale, where “1” is the least risk level and “5” is the highest risk level, were converted to identify priorities with RII.

Results: In the Sri Lankan context, it was discovered that issues with design and the approval of inaccurate building plans are the first and second major isk factors, respectively, out of the twelve categories identified. Thus, it was evident that deviations made at the design stage are the most significant risk factors, according to the Sri Lankan setting. Most of the mistakes that are made at the design stage cannot be rectified at a later stage under normal conditions, as it could incur huge costs to change the building structures.

Conclusions: The study summarizes twelve factors that contribute to fire-related incidents in Sri Lankan buildings. Among these factors, the survey data shows that incorrect building design and the approval of inaccurate building plans for construction are the primary contributors to the high frequency and severity of fire-related incidents. Despite the availability of comprehensive fire safety regulations in Sri Lanka, the research reveals a significant gap in their implementation, from design to maintenance. These findings stress the importance of incorporating fire and safety management criteria into the building design stage, covering both construction and subsequent maintenance, to prevent fire incidents in Sri Lanka.
