==Accident Chain==

Every [[accident]] as a result of a hazard is preventable by breaking the accident chain before the last link. Breaking the chain is known as [[intervention]], which is [[Reaction|reactive]], whereas reducing the [[potential]] for an accident chain at all is mitigation, which is proactive. An example of a reactive step is the [[creation]] of a [http://en.wikipedia.org/wiki/Collapse_zone collapse zone] at a structure fire. An example of a proactive step is wearing [http://en.wikipedia.org/wiki/Personal_protective_equipment personal protective equipment] at a fire call.
