How people react to a fire alarm has been studied in retrospect as well experiments. In the present study, choice of exit was examined with respect distance exits and open or closed emergency exit. The second part deals some communication aspects regarding identification signs. It is shown that subjects prefer familiar ordinary cash even if longer than nearest However, can see outside, an becomes more attractive most choose understanding signs important evacuation situation very good....

SUMMARY In fire safety engineering, information about the expected walking speed of occupants through smoke is often one factor that interest to designer. However, despite fact research already in 1970s demonstrated people tend evacuate smoke, little has been performed on topic since, and evidently, there a lack data smoke. This created situation where engineering assessments required safe escape time may be intimately associated with high uncertainties, especially for buildings which can...

Summary The use of virtual reality in human behavior fire research has the advantage being able to produce results comparable more traditional laboratory or field experiments. This method relies not only on technology employed but also participants' perception realism when exposed a emergency scenario. A scenario can be perceived as realistic based way it looks and objects operates. However, some experiments, behavioral most relevant feature obtain meaningful results. In this article,...

Unannounced evacuations were performed in both an office building and a cinema theatre order to investigate if green flashing lights at exits can influence exit choice. Also studied was how the perceived results interpreted using theory of affordances. The indicate that be used choice event fire emergency. However, effectiveness system seems depend on setting, e.g., type building. suggest emergency exit, appropriate makes stand out encourages people use it.

Abstract Fires are a major hazard resulting in high monetary costs, personal suffering, and irreplaceable losses. The consequences of fire can be mitigated by early detection systems which increase the potential for successful intervention. number false alarms current some applications very high, but could reduced increasing reliability system using complementary signals from multiple sensors. study investigates novel use machine learning event based on acoustic sensor measurements. Many...

Three evacuation experiments were performed to investigate how emergency exits should be designed. In the first two coloured flashing lights and strobe at tested compared a standard exit design. third experiment green, blue, orange red determine which colour was most appropriate for use in emergencies. Results of studies show that lights, design, increase exits. Furthermore, it is recommended green used

The aim of the project is to investigate possibility using people's mobile phones locate people in a tunnel environment phone's Wi-Fi connection. In total, 39 different trials were carried out under conditions road Stockholm, Sweden. trials, Wi-Fi-based predicted location has been compared with actual recruited 16 participants tunnel. include number group, available access points tunnel, whether phone an active or passive connection, person moving standing still and held hand stored person's...

This paper contains a proposal of new Swedish framework for performance-based design road tunnel fire safety derived from and European regulation. The overall purpose the guideline is to protect life, health, property, environment, key societal functions fire. structured into five groups requirements: #1 Proper management organisation, #2 limit generation spread smoke, #3 provide means safe self-evacuation, #4 rescue service, #5 ensure load-bearing capacity construction. Each group hybrid...

In order to provide a reliable evacuation design assessment, data showing the variation in pre-movement time is of vital importance. The many cases regarded as main period during an assessment. Therefore, forty unannounced experiments for six different occupancies were analysed quantify building evacuation, i.e., taken between receiving first cue and initiation movement towards exit evacuation. office, cinema theatres, restaurants, department stores night clubs. equipped with types alarm...
