In this mini-series of the Uncovered Witness - Fire Science Revelations, we cover the subject of the means of escape - the technical solutions in our buildings meant to allow for human evacuation in case of a fire.In the third and final episode of the mini-series, we discuss what makes or breaks the design of an evacuation sign. While it may seem like a simple design choice (make it green and make the arrow point in the correct direction?), there are, in fact, many elements that influence the human perception of the sign. We tap into the tragic fire in Daegu Metro, which illustrates what happens when the signs are present but inaccessible. We connect the design of evacuation signage to the theory of affordances, presenting a framework for evaluating its design. We give examples of good and poor affordances and explain the consequences of non-fire engineers' actions, who may unwillingly alter the sign's readability.
