Taming Chaos with a Personal Plan

When a crisis erupts due to civil unrest, natural disaster or a major terrorist attack, a number of things happen rapidly and sometimes simultaneously. First, panic ensues as people attempt to flee the immediate scene of the disaster, usually seeking safety using the same escape routes. At the same time, police, fire and emergency medical units all attempt to respond to the scene, so there can be terrible traffic and pedestrian crowd-control problems. In the event of large civil disturbances, roads can also be clogged with protesters, troops and panicked civilians. This can be magnified by smoke and fire, which can reduce visibility, affect breathing and increase panic.

In many instances, an attack or natural disaster will cause damage to electrical lines, or the electricity will be cut off as a precautionary measure. Natural gas, water and sewer lines can be damaged, causing leaks, and in the case of natural gas lines raising the threat of explosions and fire. Earthquakes and mudslides can cut roads and shut down mass transit. Often, people find themselves trapped in subway tunnels or in high-rise buildings, and they are sometimes forced to escape through smoke-filled tunnels or stairwells. Depending on the incident, bridges, tunnels, subway lines and airports can be closed or jammed to a standstill. Grocery stores are frequently inundated by people scrambling (and sometimes fighting) to obtain food and supplies.
In the midst of this confusion and panic, telephone and cell-phone usage soars. Even if the main trunk lines and cell towers are not damaged by the event or otherwise affected by the loss of electricity, this huge spike in activity quickly overloads the exchanges and cell networks. This means the ripples of chaos and disruption roll outward from the scene of the crisis as people outside the immediate vicinity of the crisis zone hear about the situation via the media and wonder what has become of loved ones who were in or near the crisis zone.
