Evacuation response behaviour of occupants in a large theatre during a live performance

E. R. Galea, S. J. Deere, C. G. Hopkin, H. Xie

This paper presents the results of an unannounced theatre evacuation involving 1200 occupants. The evacuation took place towards the end of a live theatre performance in the Marlowe Theatre in Kent, UK. In particular, Response Phase behaviours are discussed, and response time data is presented. A significant finding of this work which is different to other reported work is that the occupant response...

Increasing the Simulation Performance of Large-Scale Evacuations Using Parallel Computing Techniques Based on Domain Decomposition

A. Grandison, Y. Cavanagh, P. J. Lawrence, E. R. Galea

Fire Technology > 2017 > 53 > 3 > 1399-1438

Evacuation simulation has the potential to be used as part of a decision support system during large-scale incidents to provide advice to incident commanders. To be viable in these applications, it is essential that the simulation can run many times faster than real time. Parallel processing is a method of reducing run times for very large computational simulations by distributing the workload amongst...

Introducing Emotion Modelling to Agent-Based Pedestrian Circulation Simulation

C. Hollmann, P. J. Lawrence, E. R. Galea

Pedestrian and Evacuation Dynamics > Posters > 799-803

In agent-based pedestrian circulation models, the simulation of the pedestrian-environment interaction is mostly achieved by imposing on each agent a predefined list of goal locations which the agent visits in turn. However, in reality human behaviour in complex environments is highly dynamic and fixed plans are often changed and adjusted according to emergent conditions and the person’s individual...

Evacuation Analysis of 1000+ Seat Blended Wing Body Aircraft Configurations: Computer Simulations and Full-scale Evacuation Experiment

E. R. Galea, L. Filippidis, Z. Wang, P. J. Lawrence, more

Pedestrian and Evacuation Dynamics > Data Collection (Transport) > 151-161

Blended Wing Body (BWB) aircraft with around 1000 passengers and crew are being proposed by aircraft manufacturers. This type of aircraft configuration is radically different from conventional tube type passenger aircraft and so it is essential to explore issues related to both fire and evacuation for these configurations. Due to both the large size and the unusual nature of the cabin layouts, computer...

Numerical investigation of tube furnace toxicity measurement method (ISO 19700)

A. Mahalingam, F. Jia, Z. Wang, M. K. Patel, more

Fire and Materials > 36 > 1 > 17 - 30

ISO TS 19700 describes a test method for the generation of fire effluent and the identification and measurement of its constituent combustion products. The method has been previously accepted as a British Standard (BS 7990:2003) and as an IEC Standard (IEC 60695‐7‐50), which involves the decomposition of materials or products under various decomposing conditions occurring in different types and stages...

Human Factors Associated with the Selection of Lifts/Elevators or Stairs in Emergency and Normal Usage Conditions

M. J. Kinsey, E. R. Galea, P. J. Lawrence

Fire Technology > 2012 > 48 > 1 > 3-26

This paper presents an overview of human factors data collected via an online survey related to the use of lifts (elevators) and stairs during both circulation and evacuation scenarios. Survey participants were presented with a series of hypothetical situations and asked how they would behave. The survey was split into two broad sections, the first dealing with normal circulation usage of lifts/stairs...

A generalized relationship between the normalized yields of carbon monoxide and hydrogen cyanide

Zhaozhi Wang, Fuchen Jia, E. R. Galea

Fire and Materials > 35 > 8 > 577 - 591

Experimental studies have demonstrated that there are close correlations between the normalized yields of carbon monoxide (CO) and hydrogen cyanide (HCN) from the combustion of materials containing nitrogen. In this paper, a generalized relationship using the stoichiometric oxygen to fuel mass ratio (SOFMR) is derived to represent these correlations. Using this generalized relationship, the predicted...

Predicting toxic gas concentrations at locations remote from the fire source

Z. Wang, F. Jia, E. R. Galea, M. K. Patel

Fire and Materials > 35 > 7 > 505 - 526

A toxicity model capable of predicting toxic gas concentrations within fire enclosures utilizing the concept of the local equivalence ratio (LER) was recently developed. This paper describes an enhancement of the original model that improves its accuracy in predicting species concentrations at remote locations from the room of fire origin. The enhanced technique involves dividing the CFD computational...
