 Contents
Emergency operations or Emergency preparedness is a set of doctrines to prepare civil society to cope with natural or man-made disasters. Disaster relief is the subset of these doctrines that is concerned with recovery efforts. This is usually a government policy adapted from civil defense to prepare for nonmilitary civil emergencies before they happen.

In the U.S., most cities maintain at least a cabinet in a basement conference room with several telephone lines. In an emergency, special stationary and other supplies come out of the cabinet, and the conference room becomes the "emergency operations center." The EOC then coordinates the city's emergency effort. Even this tiny amount of preparation, with periodic drills, and coordination with civic organizations, is amazingly better than nothing.

This article covers both civil and personal preparedness, because they work together. However, civil preparedness is far less expensive per-capita, and far more valuable, even though it can be harder to arrange.

Coping with disaster has four activities: mitigation, preparation, response, and recovery.

1 Mitigations

Mitigations attempt to prevent the disaster from ever occurring, or reduce the effects of the disaster.

Floods and storm damage are the most common disasters. So, for example, a project can raise the level of a city so that a storm surge will not drown thousands. This was actually accomplished for Galveston, Texas after a devastating storm surge drowned thousands. For another example, a city can build levies to prevent floods, or (as in San Antonio, Texas) arrange for flood zones to be nonessential parks and walks.

Mitigation is the most preferred method, when it can be achieved at an acceptable cost. Mitigation is often practical for flood prevention, famine prevention, public health measures, and outages of power, water and sewer services.

2 Preparations

The most important government preparation, and one of the cheapest, is simply for a city or region to have an emergency operations center, and a practiced, region-wide doctrine for managing emergencies.

(For personal preparations, see below)

An emergency operations center (EOC) is, at minimum, a couple of cabinets in a conference room, and a rather large group of cooperative people. It should have reliable telephones and reliable access to civil and amateur radio networks. One cabinet has the radios, emergency lights and a portable generator. The other cabinet contains specialized stationary, manuals, and vests or large badges to mark people with particular roles in the emergency process.

This type of emergency center is sufficiently cheap that any region can afford two, or can have one that's fancy, and one that's cheap, in case the main one is damaged.

One common doctrine for an EOC has an emergency coordinator and assistant supported by teams of secretary, manager, assistant and runner for each of financial services, emergency services, planning, and logistics. There is usually a train of up to ten alternate people for the emergency coordinator, six to ten for each team's leader, and four for each role in the EOC. Alternates agree to carry pagers or cellular phones. Amateur radio operators train and organize to offer civil emergency communication services at their own expense, and form service organizations for this purpose.

Other preparations preposition training, supplies and equipment for use in the response and recovery stages. For example, storm shelters and evacuation routes are very helpful for extreme weather. In floods, prepositioned caches of food, fuel, boats and radio equipment can be very helpful.

Many cities also offer training for community emergency response team. Basically, this is mass training to provide teams of amateur emergency workers in every neighborhood. These are truly useful because in an emergency, real firemen are instantly overloaded, with hundreds of calls, and the ability to respond to only a few. The trained amateurs can handle roughly 90% of all emergency rescues, and man almost all other emergency services.

3 Response

Cities should plan to rescue their citizens, and plan emergency services.

Generally, a large emergency is first reported to a dispatcher for fire or police services. The dispatcher has a predefined criterion to contact the emergency services coordinator, or an alternate. The coordinator decides whether to activate the emergency operations center.

When the coordinator, and members of the supporting teams are in place, the EOC becomes active. The EOC usually begins by disaptching crews to gather information. Then it prioritizes needs, and dispatches emergency services. It also begins negotiations for emergency funding sources.

A continuing nasty problem in mass emergencies is a lack of trained responders. Most professional emergency services support about ten trucks per 100,000 people, and take at least a half hour per rescue. If a mass emergency injures or traps 2% of the population, this force will finish its rescues in about 100 hours.

In this time, up to 3/4 of the salvageable victims can die. Simple shock victims will die in about two hours. Trapped children will die of thirst in 24 hours, trapped adults and shut-ins in 48.

In mass emergencies, pretrained, volunteer community emergency response teams (CERTs) can rescue the 95% of victims that only need basic first-aid or light search and rescue skills. CERTs also can locate most of the roughly 5% of victims that require professional rescue skills. With a twenty-fold reduction in demand, and less need to search for victims, the professionals can then complete the most demanding rescues in ten to fifteen hours. Most salvageable people will be rescued.

The CERTs can also form neighborhood shelter and support groups, and arrange professional rescues, with triaged medical evacuation to prepared medical organizations via pre-arranged communcations with the emergency operations center.

The CERTs also provide a powerful method for informing and organizing mass evacuations to mass shelters. Response mobilizes emergency services, such as firemen, police, and community emergency response teams, and sheltering groups such as Red Cross. The emergency operations center is essential to this effort, because centrally-directed services are much more efficient at saving lives and property.
