Disaster Definitions
Here's What You'll Learn
ToggleA disaster is any event that causes a level of destruction, death, or injury that affects the abilities of the community to respond to the incident using available resources.
Mass casualty involves 100+ individuals
Multiple casualty involves 2 to 99 individuals
Casualties can be classified as a direct victim, indirect victim, displaced person, or refugee

Preparedness/Planning Stage: Community Disaster Planning
Plans must include:
Authority
Communication
Logistical coordination of:
Supplies and equipment
Human resources
Evacuation and rescue

Plans must be tested in different disaster scenario drills.

26
Disaster Planning Principles (from Textbook, Box 28-8)
Measures usually taken are not sufficient for major disasters.
Plans should be adjusted to people’s needs.
Planning does not stop with development of a written plan.
Lack of information causes inappropriate responses by community members.
People should be able to respond with or without direction.
Plans should coordinate efforts of the entire community, so large segments of the citizenry should be involved in the planning.
Plans should be linked to surrounding areas.
Plans should be general enough to cover all potential disaster events.
As much as possible, plans should be based on everyday work methods and procedures.

27
Disaster Planning Principles (Cont.) (from Textbook, Box 28-8, Cont.)
Plans should specify a person’s responsibility for implementing segments by position or title rather than by name.
Plans should develop a record-keeping system before a disaster occurs, regarding:
Supplies and equipment
Records of all present at any given time (to account for everyone and to identify the missing)
Identification of victims and deceased, conditions and treatment documented, and to which facility victims are sent
Backup plans need to be in place for the following:
Disruption of telephone and cell phone lines
Disruption of computer data (should be downloaded weekly and stored off site)

Response Stage

Evacuation
Search and rescue
Staging area

Red = life-threatening conditions that can be stabilized and have a high probability of survival
Black = deceased or injuries so extensive that nothing can be done to save them
Hazmat tag = contaminated

Psychological Triage
Four keys to gauging mental health impact:
Extreme and widespread property damage
Serious and ongoing financial problems
High prevalence of trauma in the form of injuries, threat to life, and loss of life
When human intent caused the disaster
In addition, panic during the disaster, horror, separation from family, and relocation or displacement may play a part
Copyright © 2015, 2011, 2007, 2001, 1997, 1993 by Saunders, an imprint of Elsevier Inc.
33
Public Health Activities
While search and rescue is going on …
Surveil for threats (e.g., contaminated water, vectors, and air quality).
Disseminate data on what has been found.
Relate health information to officials, the media, and the public as appropriate.
Gather epidemiological information.
Allocate resources and work to prevent further adverse health problems.
