When developing communication strategies, be sure that the system will be reliable and consider having at least one backup system available in the event the primary system breaks down. Certain emergency situations may require the evacuation of some or all of the occupants of the facility. First, a determination of whether evacuation might be necessary for a specific emergency should be made. This issue involves identifying the systems or procedures that may be used to reduce the impact that an emergency may have on the facility. Unlike preventative measures, which become general procedure, control and mitigation measures are only feasible when an increased threat, or an actual incident, occurs.
Thorough documentation is essential before, during, and after an emergency.
Before an emergency, good documentation ensures that those persons involved know the plan, know what is expected of them, and know how to report and identify minor problems before they contribute to an emergency. During an emergency, documentation can be a helpful tool for those implementing the plan increasing the likelihood that proper procedures are followed. Good incident documentation also provides an effective means of tracking the progress and status of an incident, and is also useful if a reconstruction of the incident is necessary. After an emergency, documentation can be helpful in improving the plan for future incidents and in streamlining any issues related to liability or insurance. Recovery involves those actions necessary to return to pre-emergency status.
