The aim of Emergency Management is to reduce the harmful effects of emergency incidents through preparedness, response, recovery, and mitigation.
Preparedness focuses on preparing equipment and procedures for use when an emergency incident occurs. This helps to reduce vulnerability to major incidents and allows for a more efficient response to disasters. Preparedness measures can take many forms ranging from focusing on individual people, locations, or incidents, to broader, government-based "all hazard" planning.
Response begins with recognition of the emergency and continues until the immediate threat to life and property has been eliminated. The goal of the response phase is to ensure the provision of basic human needs to the affected population.
Recovery starts after the immediate threat to human life has subsided and the goal of the recovery phase is to bring the affected area back to normalcy as quickly as possible.
Mitigation focuses on eliminating or reducing the impacts and risks of hazards through proactive measures taken before an emergency or disaster occurs.
