SOP 206.11
EVACUATION
In a variety of possible situations it may be
necessary to evacuate an area of the city.
This may include hazardous material emergencies, potential explosions,
floods, major fires or similar situations.
An evacuation of anything more than a single structure requires a
coordinated effort between Fire and Police commanders at the scene to ensure
that evacuation is rapid and complete without unnecessary duplication of
effort. It requires a definite plan and a method of reporting progress.
When evacuation of an area is indicated due
to an imminent Physical Hazard (fire, explosion, toxic material, etc.) the
limits of the evacuation area wil1 normally be determined by Fire Department
Command at the scene in consultation with the Police Supervisor at the
scene. The practical considerations
of what resources are available and what degree of risk is involved will
necessarily be factors in the determination of evacuation limits.
In cases involving other influences, when
time is available, the evacuation may be more deliberately planned.
Example: Evacuation for a flood
expected within six hours would be planned in the
The Police Department will
b e responsible for securing the perimeter of the evacuation area, including
traffic and pedestrian control.
The Fire Department will be responsible for
assessment of the degree of danger and the need for evacuation and for the
physical safety of personnel operating within the evacuation zone
.
Once the desired area of evacuation and the
perimeter have been established, a plan is necessary to actually effect the
desired evacuation. This will be
dependent on the resources available, (Fire, Police, other agencies)
and the type of situation. Personnel from one or several agencies may be
involved in actually alerting citizens and assisting them to evacuate.
Establish a Command
If it is infeasible to have the Police and Fire
Command Posts together, liaison will have to be established (See POLICE
LIAISON SECTOR, SOP 206.06).
Assign units or companies to evacuate specific
objectives (a building ; a block, a street; etc
. ) and report completion .
Assign Geographic Sectors to supervise operations .
Advise personnel if evacuees are to be directed to
particular Evacuation Centers.
Use P.A. function on Electronic Sirens to alert
citizens and door-to-door individual notification' Do not hesitate to make noise and
attract attention if situation is urgent. P.A. capabilities on helicopters may
also be used.
Start with areas in most immediate. danger first. Assign
priorities following degree of risk.
Any major evacuation will require and benefit from complete Public
Information notification. A Public
Information Sector must be assigned to communicate with radio and television
stations as quickly as possible to explain. exactly
what the situation is and what people involved should do. Radio and television stations will make
special announcements when requested by the Public Information Sector or by
Dispatch. These announcements can be
made using the E.O.C. Cable-TV Interrupt.
Fire Alarm operators must also be informed of
the situation to answer calls that can be expected from people wanting to
verify information.
The Dispatcher should notify hospitals that
may be effected by the situation.
In most situations it is desirable to have a
location where evacuees can be directed.
This should be a school , church or public
facility where evacuees can gather and find temporary shelter in a safe
location. This center should be located
and identified as quickly as possible.
When a long-term evacuation (more than
2-3 hours) is anticipated, contact Red Cross to set-up a temporary shelter in a safe
location. This is usually best accomplished at a
school.
The Command Post must have direct
communications with the
The Mayor or City Manager may order activation of the
In addition to conventional evacuations, some situations may
indicate different approaches.
Atmospheric Hazard. Some hazardous materials situations may pose
a problem to persons exposed to outside air only. This may be caused by a wind-carried
irritant vapor, or escaping gas. In
this case the best alternative could be to advise people to stay indoors with
windows closed and coolers shut down.
Advisory Notification. In some situations it may be necessary to
notify citizens of a potential risk and suggest that they relocate for their
own convenience.
Such a situation could occur when street flooding is expected, but no immediate threat to physical safety is indicated.
