What Shelter-in-Place Means:
One of the instructions you may be given in an emergency where hazardous
materials may have been released into the atmosphere is to shelter-in-place.
This is a precaution aimed to keep you safe while remaining indoors. (This is
not the same thing as going to a shelter in case of a storm.) Shelter-in-place
means selecting a small, interior room, with no or few windows, and taking
refuge there. It does not mean sealing off your entire home or office building.
If you are told to shelter-in-place, follow the instructions provided in this
Fact Sheet.
Why You Might Need to
Shelter-in-Place:
Chemical, biological, or radiological contaminants may be released accidentally
or intentionally into the environment. Should this occur, information will be
provided by local authorities on television and radio stations on how to
protect you and your family. Because information will most likely be provided
on television and radio, it is important to keep a TV or radio on, even during
the workday. The important thing is for you to follow instructions of local
authorities and know what to do if they advise you to shelter-in-place.
How to Shelter-in-Place
At Home:
Close and lock all
windows and exterior doors.
If you are told
there is danger of explosion, close the window shades, blinds, or curtains.
Turn off all fans,
heating and air conditioning systems.
Close the fireplace
damper.
Get your family disaster supplies kit and make sure the radio is working.
Go to an interior
room without windows that's above ground level. In the case of a chemical
threat, an above-ground location is preferable because some chemicals are
heavier than air, and may seep into basements even if the windows are closed.
Bring your pets with
you, and be sure to bring additional food and water supplies for them.
It is ideal to have
a hard-wired telephone in the room you select. Call your emergency contact and
have the phone available if you need to report a life-threatening condition.
Cellular telephone equipment may be overwhelmed or damaged during an emergency.
Use duct tape and
plastic sheeting (heavier than food wrap) to seal all cracks around the door
and any vents into the room.
Keep listening to
your radio or television until you are told all is safe or you are told to
evacuate. Local officials may call for evacuation in specific areas at greatest
risk in your community.
At Work:
Close the business.
Bring everyone into
the room(s). Shut and lock the door(s).
If there are
customers, clients, or visitors in the building, provide for their safety by
asking them to stay – not leave. When authorities provide directions to
shelter-in-place, they want everyone to take those steps now, where they are,
and not drive or walk outdoors.
Unless there is an
imminent threat, ask employees, customers, clients, and visitors to call their
emergency contact to let them know where they are and that they are safe.
Turn on
call-forwarding or alternative telephone answering systems or services. If the
business has voice mail or an automated attendant, change the recording to
indicate that the business is closed, and that staff and visitors are remaining
in the building until authorities advise it is safe to leave.
Close and lock all
windows, exterior doors, and any other openings to the outside.
If you are told
there is danger of explosion, close the window shades, blinds, or curtains.
Have employees
familiar with your building’s mechanical systems turn off all fans, heating and
air conditioning systems. Some systems automatically provide for exchange of
inside air with outside air – these systems, in particular, need to be turned
off, sealed, or disabled.
Gather essential
disaster supplies, such as nonperishable food, bottled water, battery-powered
radios, first aid supplies, flashlights, batteries, duct tape, plastic
sheeting, and plastic garbage bags.
Select interior
room(s) above the ground floor, with the fewest windows or vents. The room(s)
should have adequate space for everyone to be able to sit in. Avoid
overcrowding by selecting several rooms if necessary. Large storage closets,
utility rooms, pantries, copy and conference rooms without exterior windows
will work well. Avoid selecting a room with mechanical equipment like
ventilation blowers or pipes, because this equipment may not be able to be
sealed from the outdoors.
It is ideal to have
a hard-wired telephone in the room(s) you select. Call emergency contacts and
have the phone available if you need to report a life-threatening condition.
Cellular telephone equipment may be overwhelmed or damaged during an emergency.
Use duct tape and
plastic sheeting (heavier than food wrap) to seal all cracks around the door(s)
and any vents into the room.
Write down the names
of everyone in the room, and call your business’ designated emergency contact
to report who is in the room with you, and their affiliation with your business
(employee, visitor, client, customer.)
Keep listening to
the radio or television until you are told all is safe or you are told to
evacuate. Local officials may call for evacuation in specific areas at greatest
risk in your community.
At School:
Close the school. Activate the school’s emergency plan. Follow reverse evacuation procedures to bring students, faculty, and staff indoors.
If there are visitors in the building, provide for their safety by asking them to stay – not leave. When authorities provide directions to shelter-in-place, they want everyone to take those steps now, where they are, and not drive or walk outdoors.
Provide for answering telephone inquiries from concerned parents by having at least one telephone with the school’s listed telephone number available in the room selected to provide shelter for the school secretary, or person designated to answer these calls. This room should also be sealed. There should be a way to communicate among all rooms where people are sheltering-in-place in the school.
Ideally, provide for a way to make announcements over the school-wide public address system from the room where the top school official takes shelter.
If children have cell phones, allow them to use them to call a parent or guardian to let them know that they have been asked to remain in school until further notice, and that they are safe.
If the school has voice mail or an automated attendant, change the recording to indicate that the school is closed, students and staff are remaining in the building until authorities advise that it is safe to leave.
Provide directions to close and lock all windows, exterior doors, and any other openings to the outside.
If you are told there is danger of explosion, direct that window shades, blinds, or curtains be closed.
Have employees familiar with your building’s mechanical systems turn off all fans, heating and air conditioning systems. Some systems automatically provide for exchange of inside air with outside air – these systems, in particular, need to be turned off, sealed, or disabled.

Select interior room(s) above the ground floor, with the fewest windows or vents. The room(s) should have adequate space for everyone to be able to sit in. Avoid overcrowding by selecting several rooms if necessary. Classrooms may be used if there are no windows or the windows are sealed and can not be opened. Large storage closets, utility rooms, meeting rooms, and even a gymnasium without exterior windows will also work well.
It is ideal to have a hard-wired telephone in the room(s) you select. Call emergency contacts and have the phone available if you need to report a life-threatening condition. Cellular telephone equipment may be overwhelmed or damaged during an emergency.
Bring everyone into the room. Shut and lock the door.
Use duct tape and plastic sheeting (heavier than food wrap) to seal all cracks around the door(s) and any vents into the room.
Write down the names of everyone in the room, and call your schools’ designated emergency contact to report who is in the room with you.
Listen for an official announcement from school officials via the public address system, and stay where you are until you are told all is safe or you are told to evacuate. Local officials may call for evacuation in specific areas at greatest risk in your community.
In Your Vehicle:
If you are driving a vehicle and hear advice to “shelter-in-place” on the radio, take these steps:
If you are very
close to home, your office, or a public building, go there immediately and go
inside. Follow the shelter-in-place recommendations for the place you pick
described above.
If you are unable to
get to a home or building quickly and safely, then pull over to the side of the
road. Stop your vehicle in the safest place possible. If it is sunny outside,
it is preferable to stop under a bridge or in a shady spot, to avoid being
overheated.
Turn off the
engine. Close windows and vents.
If possible, seal
the heating/air conditioning vents with duct tape.
Listen to the radio
regularly for updated advice and instructions.
Stay where you are
until you are told it is safe to get back on the road. Be aware that some roads
may be closed or traffic detoured. Follow the directions of law enforcement
officials.
Local officials on the scene are the best source of information for your particular situation. Following their instructions during and after emergencies regarding sheltering, food, water, and clean up methods is your safest choice.
Remember that instructions to shelter-in-place are usually provided for durations of a few hours, not days or weeks. There is little danger that the room in which you are taking shelter will run out of oxygen and you will suffocate.
