Simulating the interaction of cabin crew with passengers during aircraft emergency evacuation conditions

In this paper we briefly describe new modelling capabilities within the airEXODUS evacuation model. These new capabilities involve the explicit ability to simulate the interaction of crew with passengers in managing evacuation situations

Modelling human behaviour in underground emergency situations

This presentation will discuss current developments in evacuation modelling and its role in and application to underground applications

Experimental study of the effectiveness of emergency signage

Signage systems play an important role in aiding occupants during both circulation and evacuation. Despite the fact that signage systems are an important component in building wayfinding systems, there is a lack of relevant data regarding how occupants detect, interpret and use the information conveyed by emergency signage. The effectiveness of signage systems is therefore difficult to assess. In this paper we address this issue through experimentation. The experiment involved measuring the impact of a signage system on a population of 68 test subjects who were instructed to individually vacate a building as quickly as possible via any means they thought appropriate. The evacuation path involved a number of decision points at which emergency signage was available to identify the appropriate path. Through analysis of video footage and data derived from questionnaires, the number of people who saw and utilised the signage information to assist their egress is determined. The results are then incorporated within the buildingEXODUS software and used in a demonstration of agent interaction with signage systems in a hypothetical evacuation scenario.

The use of a mathematical multicriteria decision-making model for selecting the fire origin room

Over the last three decades, the fire safety codes have been changing from a prescriptive approach to a performance-based one. Some countries, such as the USA, Sweden, New Zealand, Australia and the UK, are in an advanced stage of development and implementation of the performance-based codes. However, there are some difficulties in this process. Most of them are due to the uncertainties associated with fire design. For instance, one of the questions that need to be answered is how to select the most probable fire origin room (FOR)? On the other hand, to know where the FOR is located is also an important aspect in terms of forensic issues. Given that, to address this question is an important step for the establishment of fire designs (i.e., pre-fire phases) and also for fire investigations (i.e., post-fire phases). This paper proposes a methodology for selecting the FOR through the use of a mathematical multicriteria decision-making model: the analytical hierarchy process (AHP). The proposed method is then applied to a hypothetical study case. The results are presented and discussed in this paper.

Managing alcohol related aggression in the emergency department (Part II)

Violence in the emergency department (ED) is a global problem. In our first paper, we highlighted the potential psychological effects of alcohol intoxication, the literatures discussion of alcohol related violence in the emergency department and the importance of developing positive nurse/service user relationships. In this second paper, we discuss personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Managing alcohol related aggression in the emergency department (Part 1)

Internationally, violence in the emergency department (ED) is of a constant concern to emergency practitioners. Frequently, both original research papers and anecdotal reports emphasise the phenomenon of alcohol related aggression in the ED. In this first paper, we highlight the literatures discussion of alcohol related violence in the emergency department and the potential psychological effects of alcohol intoxication. In the second we offer personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Emergency care of children and young people

Children and young people account for a quarter of all patients treated in emergency departments in the UK, with three million children attending emergency departments every year. Emergency Care of Children and Young People prepares practitioners for the challenges of caring for children in emergency departments. Children requiring emergency care have unique and differing needs and may not respond or cooperate during an initial assessment as an adult would.

Considering theories of aggression in an emergency department context

Internationally literature emphasises concern regarding the phenomenon of violence and aggression within the emergency field. This paper emphasises the important role education and training may play in reducing the risk of staff being exposed to violent or aggressive experiences. Furthermore, the paper emphasises, explores and discusses well recognised theories relating to aggression development. These theories can be used to explain both organisational strategies designed to minimise aggression in the emergency department and situational factors contributing to the development of aggressive interactions.
