Description
Hazard prevention refers to the prevention of risks. The first and most effective stage of hazard prevention and emergency management is the elimination of hazards. If this is too timely or impractical, comes the more costly stage in emergency management: disaster mitigation

An example of a reactive step is the creation of a collapse zone at a structure fire. An example of a proactive step is wearing personal protective equipment at a fire call.
The accident chain:
