Abstract

This paper describes the application of, enhancements to, and use of surface fire spread models in predicting and mitigating fire risk in the Wildland–Urban Interface (WUI). Research and fire management strategies undertaken in the East Bay Hill region (containing the 1991 Tunnel Fire) of the San Francisco Bay area over the past decade are reported. We ascertain that surface fire spread modeling has impacted policy and decision making, resulting in a regional strategic plan where large landowners and public agencies are able to implement fire mitigation practices. Although these practices involve extensive fuel management within a buffer zone between the wildland and residential properties, the residential property owners are still at risk, as no strategy within neighborhoods can be accurately mapped using the current scale of the data and models. WUI fires are eventually extinguished by fire fighters on the ground, up close, and at the backyard scale. We argue that large-scale (backyard scale) mapping and modeling of surface fire spread is necessary to engage the individual homeowner in a fuels management strategy. We describe our ongoing research and strategies, and suggest goals for future research and development in the area of large-scale WUI fire modeling and management.

Abstract

Purpose

This paper aims to present a literature review on the problem of fire following earthquake (FFE) as a potential hazard to communities in seismically active regions. The paper is important to work toward resilient communities that are subject to extreme hazards.

Design/methodology/approach

The paper lists and reviews the historical FFE events (20 earthquakes from 7 countries), studies the available analytical tools to evaluate fire ignition and spread in communities after an earthquake, discusses the available studies on performance of individual buildings under post-earthquake fires and summarizes the current literature on mitigation techniques for post-earthquake fires.

Findings

FFE can be considered a potential hazard for urban communities that are especially not prepared for such conditions. The available analytical models are not yet fully up to the standards that can be used by city authorities for decision-making, and therefore, should be further validated. Limited structural analyses of individual buildings under FFE scenarios have been completed. Results show that the drift demand on the building frame increases during post-earthquake fires. Despite the mitigation actions, there are still urban cities that are not prepared for such an event, such as certain areas of California in the USA.

Originality/value

The paper is a complete and an exhaustive collection of literature on different aspects of FFE. Research in earthquake engineering is well advanced, while structural analyses under fire load and performance of communities under FFE can be further advanced.

Abstract

In an earlier article (The Electronic Library, April, 1985) a description is given of a method of making a KWOC index from article or document titles with a computer program which enables an indexer to combine words from the title in any way required to form indexing terms. Two versions of the program are described, an interactive one and one which compiles a KWOC index from a file of prepared data. The method has the drawback common to all KWOC indexes that the words in the title have to be used in the form in which they occur and this leads to certain shortcomings in the index such as a multiplicity of forms for what is the same term and the use of comprehensible but unconventional forms of a term. This article discusses these shortcomings and then describes the modifications made to the interactive version of the program which allow an indexer to edit the terms chosen as the index is being compiled so that consistency in the form of the terms is achieved and accepted conventions are observed. Modifications which effect the same improvements have been made to the other version of the program and these are also described. Examples of the use of both these new versions of the program are included.

Abstract

Purpose

Informal settlements are inherently unstructured in nature, lack adequate services, regularly have high population densities and can experience social problems. Thus, fires can easily propagate rapidly through such areas, leaving thousands homeless in a single fire. The purpose of this paper is to present an appraisal of various interventions and strategies to improve fire safety in informal settlements in South Africa (globally, similar settlements are known as slums, ghettos, favelas, shantytowns, etc.), considering aspects of both technical suitability and social suitability.

Design/methodology/approach

This paper focusses on three specific aspects: ignition risk management, active fire protection interventions and passive fire protection interventions. These are presented within a framework to outline how they may mitigate the impact of fires.

Findings

Often “solutions” proposed to improve fire safety either lack a sound engineering basis, thus becoming technically inefficient, or do not consider social circumstances and community responses in settlements, thereby becoming practically, socially or economically unsuitable. It must be understood that there is no “quick fix” to this significant problem, but rather a combination of interventions can improve fire safety in general. A broad understanding of the various options available is essential when addressing this problem, which this paper seeks to provide.

Practical implications

This paper seeks to provide an overview to guide policymakers and organisations by illustrating both the advantages/benefits and disadvantages/challenges of the interventions and strategies currently being rolled out, as well as potential alternatives.

Originality/value

A broad but succinct appraisal is provided that gives insight and direction for improving fire safety in informal settlements. It is hoped that the challenges associated with the fire safety interventions discussed can be addressed and improved over time.

Abstract

The paper discusses the problems encountered in the management and quantitative evaluation of fire risk and safety in a building. Rational methods for obtaining solutions to these problems are provided by non‐deterministic mathematical models rather than deterministic models. This is due to the fact that the occurrence and spread of an accidental (not arson) fire are random phenomena affected by uncertainties caused by several factors. Non‐deterministic models discussed briefly in the paper include simple statistical and probabilistic models, regression methods, probability distributions, fault and event trees and stochastic models. The paper only provides a framework for applying these models to any type of facility. For any type, it may be necessary to modify these techniques, collect all the relevant data and perform the analyses to derive results and conclusions applicable to that type.

Abstract

Purpose

Heritage housing in inner city areas represents a valuable cultural asset that belongs, in part, to the community as a whole. Despite this, the risk of destruction by fire in closely spaced heritage housing has not received a great deal of research attention. The purpose of this paper is to identify potential faults in building fabric that may result in unacceptable fire safety risks to irreplaceable heritage streetscapes.

Design/methodology/approach

This paper examines a sample of publically administered heritage houses in inner Sydney. A condition survey looks at the occurrence of noted defects, or non-compliances to the current building regulations, in fire separation between attached or closely spaced occupancies.

Findings

Fire spread between adjacent buildings is identified as a potential hazard which needs to be addressed in order to ensure both the sustainability of the remaining heritage housing stock and the safety of the occupants.

Research limitations/implications

While the survey is small, it represents a significant proportion of a dwindling stock of nineteenth century heritage housing in public ownership in Sydney.

Practical implications

Based on the results of the survey, a recommendation has been made in regard to improving building surveying practice when dealing with renovation of heritage housing.

Social implications

Concern over the diminishing availability of social housing in inner city locations indicates the need for more attention to the fire safety of the remaining stock.

Originality/value

The research provides original data on the level of fire safety risk in a regional cluster of heritage housing.

Abstract

Purpose

The purpose of this paper is to investigate approaches pertaining to qualitative fire risk assessment of existing hotel facilities, for the purpose of identifying and eliminating fire hazards, and meeting requirements of the current legislation.

Design/methodology/approach

The paper carries out several research activities, including: identifying the set of factors that render hotel facilities a high‐risk type of facilities in fires; investigating potential high‐risk areas to fires in hotels; exploring the role of hotel managers towards operating safe hotel facilities; discussing the concept of fire risk management, and the role of fire safety inspections as a risk mitigation strategy to ensure the adherence of existing hotels to fire safety legislation; and describing a methodical approach that fire safety inspectors can follow while conducting fire safety inspections. The paper also presents the development of a qualitative fire risk assessment tool, whereby existing hotel facilities can be assessed.

Findings

The paper establishes that hotel facilities are a high‐risk type of facilities in fire emergencies due to the combination of several risk factors. The fire risk assessment tool provides 76 items to assess, in seven main divisions, including exits, fire protection systems, electrical, fire doors, hazardous materials, housekeeping and miscellaneous.

Originality/value

This paper provides for a better comprehension of the roles of hotel managers towards operating safe hotel facilities. The paper emphasizes adherence of existing hotels to fire safety legislation to ensure the minimum level of safety for guests in all hotel properties. It serves to enhance the understanding of the potential dangers present in hotel facilities. It is of practical value to hoteliers responsible for the day‐to‐day operation of hotel facilities and for surveyors inspecting such properties.

Abstract

Purpose

Post-earthquake fire (PEF) can lead to a rapid collapse of structures partially damaged by earthquake. As there is almost no established PEF provisions by codes and standards, PEF investigations are therefore needed for those buildings. The paper aims to discuss these issues.

Design/methodology/approach

A non-linear PEF analysis comprises three steps, which are the application of gravity loads, earthquake loads and then fire loads. As a fire generally initiates on one floor and then spreads to other floors, applying a sequential fire is more realistic than applying a concurrent fire on several floors. Hence, in this study, the fire is applied sequentially to the floors with a time delay.

Findings

The results indicate a substantial reduction in the resistance of the damaged frame when subjected to PEF. In addition, the results of applying the PEF sequentially is more realistic than the concurrent fire.

Research limitations/implications

It was better to perform an experimental test to have a better understanding of the issue.

Originality/value

PEF can potentially result in a catastrophe in areas located in seismic regions. Thus, investigating the effect of PEF on previously damaged structures is of importance.

Abstract

Explains why the safety measures in England and Ireland have been unsuitable for application to historic buildings and points out that the protection of property has rarely been considered. Details how inflexible the fire safety legislation and regulations have been. The conflict between officers dealing with planning conservation and building control officers led to a review of regulations. Outlines these reviews, and the flexibility and changes which were brought about with the introduction of the new 1991 Building Regulations. Discusses the new approach to fire safety in historic buildings and the results it has achieved, for example, recognition of smoke damage and detection systems.

Abstract

Purpose

The purpose of this paper is to investigate a set of preventive measures required for mitigating fire risks in big box retail facilities.

Design/methodology/approach

The paper identifies the potential sources of ignition and fuel in big box retail facilities. It describes the variety of hazardous situations commonly found in such facilities worldwide. The paper then endeavors to discuss the series of fire protection challenges that could be faced during fire emergencies. It also explores the challenges of evacuation and rescue in such mega store facilities.

Findings

Mega stores, distribution centers and large retail stores are amongst the most challenging occupancies from a fire protection perspective. Fires can occur in big box retail facilities at any time and from a number of causes. These facilities represent a type of occupancy that poses considerable challenges to both fixed fire suppression systems and fire departments in cases of fire emergencies. The paper also describes the responsibilities of building management staff towards their employees and the public. Facility managers should always seek proactive measures to reduce the risk of fire and fire spread in big box retail facilities. These measure include providing sufficient number and capacity of exits; clear exit access; efficient smoke detection systems; voice communication systems; and efficient automatic sprinkler systems.

Quality/value

This paper serves to increase the awareness about fire and its effects in mega store facilities. The paper provides practical value to property directors and facility managers responsible for the daily operations of mega store facilities and for surveyors inspecting such properties.
