Sheltering
in place is required when a hazard is outdoors and the conditions are unsafe
for citizens without the proper protective equipment. You may be advised to
shelter in place for tornadoes, human-caused threats, chemical spills or
biological or radiological hazards. If and when an announcement to shelter
in place is given, you should do the following:
Natural Hazards
For
natural hazards, seek shelter in an interior room with no windows or in the
basement with a solid enclosure above and around you.
Chemical Hazards
For
hazards that are chemical or radiological in nature outside of your home or
office, we are less concerned with structural integrity, but rather how very
small particles can enter it.
In these cases you should stay indoors. Don’t go outside for any reason. Close
all open doors and windows. Turn off your furnace, air conditioner, or
ventilation system and find a room or area without windows and outside vents.
Depending on the type of incident occurring outside, you may need to seal doors
and windows with plastic and tape.
Biological Hazards
For
hazards that are chemical or radiological in nature outside of your home or
office, we are less concerned with structural integrity, but rather how very
small particles can enter it.
In these cases you should stay indoors. Don’t go outside for any reason. Close
all open doors and windows. Turn off your furnace, air conditioner, or
ventilation system and find a room or area without windows and outside vents.
Depending on the type of incident occurring outside, you may need to seal doors
and windows with plastic and tape.
