They have their own sets of attributes, how quickly they can walk, how quickly they're likely to respond to a fire, their knowledge of the building, which exit they're likely to use, their drive, and how keen they are to get out of the structure. So we have a collection of physical attributes that describes individual people. All these parameters then interact to describe how that person is going to respond to the particular incident that they're faced with. Well, we're using the Exodus computer model while the building is still in the planning phase, to try and design the structure so that it is more efficient in terms of evacuating people. I don't think it's possible to design a structure that is one hundred per cent fire proof.
Any structure has the capacity to burn.
And because it's going to burn, it's going to produce smoke, heat, toxic gases and so on. Because of that, you need to make sure that you can get people out of that structure as quickly and efficiently as possible, and that's why you need evacuation models to help design structures so that the evacuation of people is going to be as efficient as possible. Fire safety science and engineering is a fascinating subject, because it brings together many different disciplines in the pursuit of a safer environment.
