Abstract [en]

Introduction: Firefighters are exposed to significant levels of heat stress during duty, and therefore fire-fighting exercises in hot environments must be regularly performed [1]. This study aimed to investigate the effect of extreme heat exposure on physiological responses during and after one simulated smoke dive.

Methods: Nineteen professional male firefighters (43 ± 8 years, 84 ± 7 kg) wearing protective clothing and self-contained breathing apparatus with a total weight of 108 ± 7 kg participated. They performed a 15-min simulated smoke dive in a two-floor heat chamber (HEAT) at ambient temperatures ranging from 110 °C to 272 °C, followed by 5-min up and down stair walking outside the heat chamber. Heart rate (HR), gastrointestinal temperature (Tgi) and skin temperatures (Tsk) were registered continuously during the test.

Results: Tgi increased significantly from start (37.5 ± 0.3 °C) to the peak of HEAT (38.4 ± 0.4 °C) and continued to increase after the heat exposure and stair walking (39.6 ± 0.5 °C). The HR also increased significantly from start (92 ± 14 bpm) to the peak of HEAT (185 ± 13 bpm) and further increased after the heat exposure and stair walking to a maximum of 190 ± 13 bpm.

Conclusion: A 20-min firefighter smoke dive in hot environments induced high physiological strain on the firefighters, and Tgi and HR continued to increase after the heat exposure. This must be considered during live fire events when repeated smoke dives are required.

Abstract [en]

Experiences regarding personal protection water mist systems installed in dwellings. Personal protection water mist systems can produce a water mist that can cool down and limit a fire in a small area in a dwelling. The system is equipped with sensitive detectors which can activate the system in the early stages of the fire and limit the fire spread, and in some cases extinguish the fire. This gives more time for evacuation, which can be especially important for vulnerable people with risk factors, like impaired cognitive and physical functioning. The goal of this study has been to map the experiences in Norway regarding personal protection water mist systems, considering how the municipalities have experienced the work related to the systems and whether the systems have activated and saved lives. This will shed light upon whether mobile water mist systems are appropriate measures for vulnerable people in the society, and the risk factors that determine whether the measure is appropriate or not. This study has used literature studies, questionnaires, and interviews to map the experiences of personal protection water mist systems in Norway. The results showed that personal protection water mist systems installed in Norwegian dwellings have been activated in connection with fire outbreaks, and thus limited or extinguished the fire. This has saved lives on several occasions and reduced the damage potential. There are many people who have risk factors that make it appropriate to install a mobile water mist system in their home, but there are also exceptions. The risk factors that indicate that it is beneficial to install mobile water mist systems in Norwegian dwellings are - Impaired cognitive abilities - Impaired physical abilities - Drug and alcohol problems - Smoking - Living alone The systems are particularly suitable when several of the risk factors are present at the same time. It was also shown that personal protection water mist systems are not suitable for mobile people who spend time in several places in the home and are therefore often outside the system's coverage area. Personal protection water mist systems are not recommended for people who may have the potential to sabotage the system. In questionnaires and interviews, it emerged that there are big differences between how Norwegian municipalities work with assigning, installing, operating, and maintaining personal protection water mist systems. In larger municipalities, there are more people who rely on routines and formal processes for the work, and there is therefore a greater proportion of the larger municipalities who distribute the facilities out to individuals than in the small municipalities where the work is more characterised by informal routines and personal relations. 3 Based on the results from this study, it is our opinion that the following aspects should be covered by future work: • Need for a new and updated cost-benefit analysis for personal protection water mist systems. • Need for a better statistical basis for assessment of the personal protection water mist systems. • Need for a Norwegian test standard for personal protection water mist systems. • Need for clear guidelines for assignment, procurement, installing, operation, and maintenance of personal protection water mist systems.

Abstract [en]

This article presents an analysis of a fire in a municipal apartment building used as housing for people with challenges connected to drug addiction. The fire took place in Norway 7th of August 2021. The incident happened during the night and the fire was spreading quickly and intensely via the external wooden balconies. The combination of risk factors both connected to the fire development and the characteristics of the occupants raises the potential for fire fatalities. This analysis seeks to understand why the fire spread with such a speed, and how everyone in the building survived without injuries. The analysis identified both technical and human factors that may help to answer these questions. The findings suggest that there were deficiencies connected to the technical fire safety design that if improved could have reduced the fire damage. Factors promoting the fire spread and fire intensity include the choice of wood material used in the construction of the balconies, no sprinkler system installed on the balconies and a large fire load on the balconies caused by the occupants’ tendency to accumulate possessions on the balconies. Factors contributing to the outcome of no injuries or fatalities included occupants being awake during these late hours, and the strong social network between them. Such a network should be seen as a positive factor regarding robustness against fire and should be encouraged.

Abstract [en]

Fires are devastating events that may harm humans, properties and the environment. Authorities, organisations, companies and societies should be able to learn from fire incidents to reduce the probability and impact of future fires. To achieve a reduction in fires and their consequences, an effort is needed from multiple actors and both technical, organisational and individual changes would be necessary. Importantly, we therefore consider change as a prerequisite for learning. So how can we as a society change or modify our efforts for prevention and mitigation of fires? A learning approach often starts with some form of inquiry about the occurred accidents – an investigation. This investigation can take many forms: the fire services’ own evaluations of the response to a fire, an authority’s assessments of the compliance and fit of their regulations, a company’s analysis of internal rules and organisation, and the police’s investigation of criminal issues. Investigations require highly skilled professionals using often multidisciplinary skills such as knowledge in human behaviour, fire dynamics, electrical systems, mechanical processes and many more. A fire investigator may use many different techniques and tactics, to figure out how the fire started, what fault led to the fire, what made the fire develop the way it did and, also what factors and measures that worked well in the fire. The investigator can work for the fire service, the police, insurance companies, hired private fire investigators or in larger companies, to mention a few. However, not all fires are investigated in Norway, and there is also a large number of incidents that is concluded with an unknown fire cause. The aim of our research has been to increase the society’s capacity to learn from fires. We have two main objectives contributing to the aim: 1. Obtain knowledge on the preconditions for learning from fires in Norway. 2. Provide recommendations to increase learning from fires in Norway. Leading to these main objectives, we shed light on investigations, examinations, databases and routines related to the different actors, and importantly, the actors’ beliefs, collaboration and practices related to fire prevention and learning. The main corpus of material in this study is interviews with actors relevant for learning from fires in Norway. The informants were from the fire service, the police, educational system, insurance, authorities and organisations with interest in fire safety. The interviews were related to themes like cooperation inside and outside the organisation, resources and databases, how the interviewees see the fire investigation area today and how it should be improved. The findings were then divided into the Pentagon model’s five categories: • formal structure • technology and infrastructure • culture • interaction • relations and network The findings from the interviews and the reasons behind them are extensive and are elaborated upon in the report, but the main points are summarised here. Generally, we see clearly that learning from fires is a complex issue. It does not only encompass obtaining the correct technical insights from a fire scene, but also informal aspects like the personal relations and how the fire services are organised. Further, we see that fire investigation in Norway lack both the quality and quantity needed to obtain sufficient knowledge on fires that occur. The approaches, mandates and focus vary greatly with each actor, and this affects the coordination, cooperation, and systematic work of learning from investigations. High variation can also be found in the fire services’ own evaluations of their own fire-fighting efforts, which leads to regionally different methodology and terminology. This has an additional negative impact on the cooperative work even between fire departments. The cooperation is also varying when it comes to the sharing of knowledge which is prevalent between all actors involved in fire investigation. Little cooperation is formalised and therefore most cooperation on investigation and learning, as well as the sharing of knowledge and experiences, are done through individual and personal relations. This is also true inside the fire services where personal experiences and social learning is preferred to more systematic evaluation of fires and formal education. This creates a potential conflict with efforts of standardising work and learning processes. Lastly the lack of resources in preventive work in fire and rescue services and the police, especially in the investigation phase, hinders the possibility to learn effectively from fires and to convey the experiences from them. The difference in status between preventive and preparedness efforts in these public services is still relevant today.
