A review of the literature on human behaviour in dwelling fires
Most fire-related injuries and fatalities in the UK, and other parts of the world, continue to occur during fires in the home – incidents where it is acknowledged that human factors play a contributing role. Yet the field of fire safety lacks an up-to-date review of the literature on human behaviour during fires in domestic spaces. Given there is now a growing body of work looking at human behaviour in dwelling fires, a review of the literature in this area is timely. Drawing from published studies, this paper sets out what is currently known about human behaviour in dwelling fires and highlights the differences that appear to exist between these spaces and what is known and accepted about human behaviour in public, commercial and industrial spaces. This paper then goes on to consider the nature of “fire risk”, arguing that much of the work in this area continues to conflate, or fails to recognise the existence of, different types of risk profiles, instead considering fire risk as a single type of risk, based mainly on factors related to fatalities. However, research findings point towards fire risk as at least three separate forms: the risk of a fire occurring, the risk of fire injury and the risk of fire fatality. By drawing together the literature on human behaviour in dwelling fires this paper argues that those who survive dwelling fires cannot be considered as “near miss fatalities”, but instead must be treated as a separate and distinct group

From data to difference – considering the application of a large-scale database of human behaviour in accidental dwelling fires
This paper outlines six newly developed insight themes designed as a tool to engage the United Kingdom Fire and Rescue Service (FRS) in a discussion about the importance of human behaviour in accidental dwelling fires (ADFs), a subject that has received limited attention compared to the study of human behaviour in other environments. Central to a wider research programme focussing on the public's perspective of an ADF is an important project, named LIFEBID (Lessons in Fire & Evacuation Behaviour in Dwellings). LIFEBID will create the world's first large-scale database of human behaviour in ADFs. The LIFEBID database will generate new data comprising hundreds (and potentially) thousands of survey responses from members of the public who have directly experienced an ADF. The insight themes provide a means to engage with FRS stakeholders about the relevance of the work for them. Within this paper the insight themes consider the importance of this subject for the UK FRS, which is a key stakeholder, both in the research development and the application of its findings. The insight themes allow logical presentation of emerging and potential applications in a format that is easily understood

Recollection of flame height and smoke volume in domestic fires
When a domestic fire occurs, how well do people perceive and recall the fire hazards they encounter? Although much research has been conducted on threat or risk perception and memory for threatening stimuli, to the authors' knowledge no studies have systematically tested how well people perceive and recall the threat stimulus in a fire context. This is an important topic given that domestic fires are usually the main source of fire-related injuries and deaths, and human behaviour is believed to play a significant role in such outcomes. Moreover, eyewitness testimonies play a significant role in subsequent fire, insurance and coroner investigations. The current study – part of wider research on human behaviour in domestic fires, called LIFEBID – sought to address the gap in knowledge by conducting an online experiment testing participants' (a) memories for the size of the flames and smoke witnessed in a mock kitchen fire, and (b) reported willingness to engage with the fire hazards. Participants' behaviours and attitudes in relation to other risky activities and control over events were also measured. The results revealed that accurate recollections of flame height and smoke volume can be obtained from members of the public, in certain cases. Accuracy was negatively impacted when the flames and smoke witnessed were larger in size. The size of the fire hazards also had an impact on participants' willingness to engage with the hazards, moderating the number who stated that they could have successfully extinguished the flames or would have entered the room with the smoke. Although there were signs that many participants recognised the risks posed by the larger hazards, a not inconsiderable number were still willing to engage with them. Being someone who takes greater risks in a health/safety domain and believing in one's ability to control what happens to oneself did not explain this finding. There is a clear need for a deeper investigation into people’s perceptions of fire hazards in a domestic fire context and their associated behaviours and fire outcomes
Perception and recollection of fire hazards in dwelling fires
Current understanding of dwelling fire injury outcomes is impacted by data limitations, confounds, and failures to adequately examine occupant behaviour. For instance, research rarely considers: occupant perception of fire hazard properties (e.g. size of flames/smoke when first encountered); resultant engagement (enter smoky room, tackle flames); whether hazard size percepts are accurate when recollected for investigators; and what the best recollection method is. Two experiments (N = 141, 132) presented short videos of kitchen fires where hazard size was either Small, Mid or Large. Immediately after seeing this (Experiment 1), or after a delay (Experiment 2), participants’ performance at recollecting hazard size and their willingness to (hypothetically) engage with the hazards was tested. Recollection performance was compared across three methods. Interestingly, free recall resulted in poor performance but performance improved by 2-3 times when using two types of layperson-friendly descriptors (text, pictures) that allowed hazard size to be referenced to other scene elements. Pictures had a slight advantage over text descriptors. Larger hazards were recollected less accurately than small ones, albeit still somewhat meaningfully; the exception was mid-sized smoke and attentional narrowing effects are discussed. Importantly, while increased hazard size reduced willingness, a concerning percentage of participants nevertheless considered engaging with the largest hazards; such risky behaviours may explain injury outcomes. Prior fire experience and gender affected recollection and willingness, often interacting with hazard size. Delayed recollection and individual differences did not. These findings suggest occupant behaviour, characteristics and hazard size data need capturing to help assess fire injury risks
RECOLLECTION OF FLAME HEIGHT AND SMOKE VOLUME IN DOMESTIC FIRES

Although much research has been conducted on threat or risk perception and memory for threatening stimuli, to the authors' knowledge no studies have systematically tested how well people perceive and recall the threat stimulus in a fire context.
