Hazard A hazard is any object, situation, or behavior that has the potential to cause injury, ill health, or damage to property or the environment.
Emergency An emergency is a situation that poses an immediate risk to health, life, property, or environment. Most emergencies require urgent actions to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath.
Risk Risk is the potential of gaining or losing something of value. Values (such as physical health, social status, emotional well-being, or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen (planned or not planned ).
Vulnerability Vulnerability describes the characteristic and circumstances of a community, system or asset that makes it susceptible to the damaging effects of a hazard. There are many aspects of Vulnerability , arising from various physical, social, economic, and environmental factors.
Disaster management Disaster management aims to reduce, or avoid, the potential losses from hazards and appropriate assistance to victims of disaster, and achieve rapid and effective recovery.
Principles of disaster management Disaster management is the responsibility of all spheres of government. Disaster management should use resources that exist for a day-to-day purpose. Organizations should function as an extension of their core business.
Individuals are responsible for their own safety. Disaster management planning should focus on large-scale events.
Disaster management cycle The Disaster management cycle illustrates the ongoing process by which governments, businesses, and civil society plan for and reduce the impact of disasters, react during and immediately following a disaster, and take steps to recover after a disaster has occurred.
Phases of disaster management cycle Mitigation - Minimizing the effects of disaster. Examples : building codes and zoning; vulnerability analyses; public education. Preparedness - Planning how to respond. Examples : preparedness plans; emergency exercises/training; warning systems.
Response - Efforts to minimize the hazards created by a disaster. Examples : search and rescue; emergency relief . Recovery - Returning the community to normal. Examples : temporary housing; grants; medical care.
