Most of us have been to a sporting event at one time or another in our lives. In this day and age, we can spot the safety improvements which have been added the stadiums and arenas due to tragedies which struck in the past: fire doors with lit EXIT signs overhead; stadiums made of concrete, steel, and plastic rather than wood; sprinkler systems and fire extinguishers in multiple locations. One of the tragedies which led to more thorough precautions being taken in stadiums in Great Britain started with a dropped cigarette during a football match and ended with 56 dead.
