Emergency management

society Maturity 9-11 Next article →

Emergency management is the systematic process of reducing a community's vulnerability to hazards. These hazards can be natural, like hurricanes, or man-made, like terrorism.

This field focuses on destructive events that overwhelm a community's ability to handle them alone. Professionals manage these crises by conducting search and rescue operations. They also provide basic needs to affected individuals and issue evacuation alerts. Effective management requires collaboration between households, non-governmental organizations, and various levels of government. This includes local, provincial, and federal authorities working together.

Experts organize their work into five distinct phases. The first phase is prevention, which aims to provide permanent protection from disasters. This might include pandemic prevention or strict environmental planning. The second phase is mitigation, which involves proactive measures to reduce the impact of a hazard. For example, building houses on stilts can mitigate flood risks.

The third phase is preparedness, which involves training and planning before an event occurs. This includes safety drills for fires, tornadoes, or earthquakes. The fourth phase is response, which is the immediate action taken during a disaster. Finally, the fifth phase is recovery, which focuses on cleaning up and rebuilding.

Mitigation strategies often involve specific engineering or structural changes. In earthquake-prone areas, people might install an earthquake valve. This device instantly shuts off the natural gas supply to prevent fires. They may also perform seismic retrofits on buildings.

Securing furniture, water heaters, and breakables to walls is another common tactic. In flood-prone areas, builders might use stilts or build above the 100-year or 500-year flood levels. To manage electricity black-outs, people may install generators. Other examples include building storm cellars, fallout shelters, or reinforced safe rooms for protection against extreme wind.

Emergency planning follows a cyclical process similar to other risk management disciplines. This cycle involves identifying risks and then ranking or evaluating them. Professional organizations provide essential guidelines for this process. These include ASIS International and the National Fire Protection Association (NFPA). The International Association of Emergency Managers (IAEM) also publishes helpful information.

Effective plans must include trained staff members who are responsible for decision-making. Companies should also conduct regular testing of their plans. If several businesses occupy one space, they should implement joint emergency plans. Training should include internal staff, contractors, and civil protection partners.

Global cooperation has shaped how nations approach these risks. In January 2005, 168 governments met at the World Conference on Disaster Reduction. This meeting took place in Kobe, Hyogo, Japan. The participants adopted a 10-year plan known as the Hyogo Framework for Action.

This framework helps make the world safer from natural hazards. In the United States, the Government Emergency Telecommunications Service supports many different groups. It provides emergency access and priority handling for calls over the public switched telephone network. This helps federal, state, local, and tribal government personnel stay connected during a crisis.

Recovery efforts present significant occupational hazards for workers. Physical exposures can include injuries from sharp or blunt objects hidden in floodwaters. These injuries, such as lacerations or fractures, can lead to infections from contaminated water.

Earthquake survivors may also face crush injuries, burns, or electric shocks from falling debris. Chemical exposures are another major concern. Hazardous materials can be released directly during a disaster or indirectly afterward. For example, a hurricane might cause asbestos fibers to be released from a collapsing building.

Even the intentional use of chemicals, like chlorine for water treatment, must be managed.

Biological hazards are also common during the recovery phase. Mold growth is a frequent problem in buildings following floods, hurricanes, or tsunamis. Warm and humid conditions encourage the growth of molds like Aspergillus, Cladosporium, Alternaria, and Penicillium. These can cause anything from eye irritation to severe asthmatic reactions.

Workers should use N-95 masks or respirators when removing mold. Additionally, workers must manage psychosocial exposures. The CDC notes that responders face intense stress from witnessing suffering or making life-and-death decisions. Organizations like the Substance Abuse and Mental Health Services Administration (SAMHSA) provide resources to help manage this stress.
