FEDERAL EMERGENCY MANAGEMENT AGENCY,
ARE YOU READY?
The contents of this document is primarily aimed at the USA but most points are applicable to the Rest of the World.
National Security Emergencies
In addition to the natural and technological hazards described in this publication, Americans face threats posed by hostile governments or extremist groups. These threats to national security include acts of terrorism and acts of war. The following is general information about national security emergencies. For more information about how to prepare for them, including volunteering in a Citizen Corps program, see the For More Information chapter at the end of this guide.
Terrorism
Terrorism is the use of force or violence against persons or property in violation
of the criminal laws of the United States for purposes of intimidation, coercion
or ransom. Terrorists often use threats to create fear among the public, to
try to convince citizens that their government is powerless to prevent terrorism,
and to get immediate publicity for their causes. Acts of terrorism range from
threats of terrorism, assassinations, kidnappings, hijackings, bomb scares and
bombings, cyber attacks (computer-based), to the use of chemical, biological
and nuclear weapons. High-risk targets include military and civilian government
facilities, international
airports, large cities and high-profile landmarks. Terrorists might also target
large public gatherings, water and food supplies, utilities, and corporate centers.
urther,
they are capable of spreading fear by sending explosives or chemical and biological
agents through the mail. In the immediate area of a terrorist event, you would
need to rely on police, fire and other officials for instructions. However,
you can prepare in much the same way you would prepare for other crisis events.
Preparing for terrorism
1. Wherever you are, be aware of your surroundings. The very nature of terrorism
suggests there may be little or no warning.
2. Take precautions when traveling. Be aware of conspicuous or unusual behavior.
Do not accept packages from strangers. Do not leave luggage unattended. Unusual
behavior, suspicious packages and strange devices should be promptly reported
to the police or security personnel.
3. Do not be afraid to move or leave if you feel uncomfortable or if something
does not seem right.
4. Learn where emergency exits are located in buildings you frequent. Notice
where exits are when you enter unfamiliar buildings. Plan how to get out of
a building, subway or congested public area or traffic. Note where staircases
are located. Notice heavy or breakable objects that could move, fall or break
in an explosion.
5. Assemble a disaster supply kit at home and learn first aid. Separate the
supplies you would take if you had to evacuate quickly, and put them in a backpack
or container, ready to go.
6. Be familiar with different types of fire extinguishers and how to locate
them. Know the location and availability of hard hats in buildings in which
you spend a lot of time.
Protection against cyber attacks
Cyber attacks target computer or telecommunication networks of critical infrastructures
such as power systems, traffic control systems, or financial systems.
Cyber attacks target information technologies (IT) in three different ways.
First, is a direct attack against an information system through the wires
alone (hacking). Second, the attack can be a physical assault against a critical
IT element. Third, the attack can be from the inside as a result of compromising
a trusted party with access to the system.
1. Be prepared to do without services you normally depend on that could be disrupted
electricity, telephone, natural, gas, gasoline pumps, cash registers,
ATM machines, and internet transactions.
2. Be prepared to respond to official instructions if a cyber attack triggers
other hazards, for example, general evacuation, evacuation to shelter, or shelter-in-place,
because of hazardous materials releases, nuclear power plant incident, dam or
flood control system failures. Preparing for a building explosion Explosions
can collapse buildings and cause fires. People who live or work in a multi-level
building can do the following:
1. Review emergency evacuation procedures. Know where emergency exits are located.
2. Keep fire extinguishers in working order. Know where they are located, and
learn how to use them.
3. Learn first aid. Contact the local chapter of the American Red Cross for
information and training.
4. Building owners should keep the following items in a designated place on
each floor of the building.
Portable, battery-operated radio and extra batteries
Several flashlights and extra batteries
First aid kit and manual
Several hard hats
Fluorescent tape to rope off dangerous areas
Bomb threats
If you receive a bomb threat, get as much information from the caller as possible.
Keep the caller on the line and record everything that is said. Then notify
the
police and the building management. If you are notified of a bomb threat, do
not touch any suspicious packages. Clear the area around suspicious packages
and notify the police immediately. In evacuating a building, dont stand
in front of windows, glass doors or other potentially hazardous areas. Do not
block sidewalk or streets to be used by emergency officials or others still
exiting the building.
Suspicious parcels and letters
Be wary of suspicious packages and letters. They can contain explosives, chemical
or biological agents. Be particularly cautious at your place of employment.
Some typical characteristics postal inspectors have detected over the years,
which ought to trigger suspicion, include parcels that
Are unexpected or from someone unfamiliar to you.
Have no return address, or have one that cant be verified as legitimate.
Are marked with restrictive endorsements, such as Personal,
Confidential or Do not x-ray.
Have protruding wires or aluminum foil, strange odors or stains.
Show a city or state in the postmark that doesnt match the return
address.
Are of unusual weight, given their size, or are lopsided or oddly shaped.
Are marked with any threatening language.
Have inappropriate or unusual labeling.
Have excessive postage or excessive packaging material such as masking
tape and string.
Have misspellings of common words.
Are addressed to someone no longer with your organization or are otherwise
outdated.
Have incorrect titles or title without a name.
Are not addressed to a specific person.
Have handwritten or poorly typed addresses.
With suspicious envelopes and packages other than those that might contain
explosives, take these additional steps against possible biological and chemical
agents.
Refrain from eating or drinking in a designated mail handling area.
Place suspicious envelopes or packages in a plastic bag or some other
type of container to prevent leakage of contents. Never sniff or smell suspect
mail.
If you do not have a container, then cover the envelope or package with
anything available (e.g., clothing, paper, trash can, etc.) and do not remove
the cover.
Leave the room and close the door, or section off the area to prevent
others from entering.
Wash your hands with soap and water to prevent spreading any powder to
your face.
If you are at work, report the incident to your building security official
or an available supervisor, who should notify police and other authorities without
delay.
List all people who were in the room or area when this suspicious letter
or package was recognized. Give a copy of this list to both the local public
health authorities and law enforcement officials for follow-up investigations
and advice.
If you are at home, report the incident to local police. In the immediate
area of a terrorist event, leave quickly and orderly. Listen to police, fire,
and other
officials for instructions.
What to do if there is an explosion
Leave the building as quickly as possible. Do not stop to retrieve personal
possessions or make phone calls. If things are falling around you, get under
a sturdy
table or desk until they stop falling. Then leave quickly, watching for weakened
floors and stairs and falling debris as you exit.
1. If there is a fire:
Stay low to the floor and exit the building as quickly as possible.
Cover your nose and mouth with a wet cloth.
When approaching a closed door, use the back of your hand to feel the
lower, middle and upper parts of the door. Never use the palm of your hand or
fingers to test for heat: burning those areas could impair your ability to escape
a fire (i.e., ladders and crawling).
If the door is NOT hot, open slowly and ensure fire and/or smoke is not
blocking your escape route. If your escape route is blocked, shut the door immediately
and use an alternate escape route, such as a window. If clear, leave immediately
through the door. Be prepared to crawl. Smoke and heat rise. The air is clearer
and cooler near the floor.
If the door is hot, do not open it. Escape through a window. If you cannot
escape, hang a white or light-colored sheet outside the window, alerting fire
fighters to
your presence
Heavy smoke and poisonous gases collect first along the ceiling. Stay
below the smoke at all times.
2. If you are trapped in debris:
Do not light a match.
Do not move about or kick up dust. Cover your mouth with a handkerchief
or clothing.
Rhythmically tap on a pipe or wall so that rescuers can hear where you
are. Use a whistle if one is available. Shout only as a last resort when you
hear sounds and think someone will hear youshouting can cause a person
to inhale dangerous amounts of dust.
Chemical and Biological Weapons
In case of a chemical or biological weapon attack near you, authorities will
instruct you on the best course of action. This may be to evacuate the area
immediately,
to seek shelter at a designated location, or to take immediate shelter where
you are and seal the premises. The best way to protect yourself is to take emergency
preparedness measures ahead of time and to get medical attention as soon as
possible, if needed.
Chemical
Chemical warfare agents are poisonous vapors, aerosols, liquids or solids that
have toxic effects on people, animals or plants. They can be released by bombs,
sprayed from aircraft, boats, or vehicles, or used as a liquid to create a hazard
to people and the environment. Some chemical agents may be odorless and tasteless.
They can have an immediate effect (a few seconds to a few minutes) or a delayed
effect (several hours to several days). While potentially lethal, chemical agents
are difficult to deliver in lethal concentrations. Outdoors, the agents often
dissipate rapidly. Chemical agents are also difficult to produce.
There are six types of agents:
Lung-damaging (pulmonary) agents such as phosgene,
Cyanide,
Vesicants or blister agents such as mustard,
Nerve agents such as GA (tabun), GB (sarin), GD (soman), GF, and VX,
Incapacitating agents such as BZ, and
Riot-control agents (similar to MACE).
Biological
Biological agents are organisms or toxins that can kill or incapacitate people,
livestock and crops. The three basic groups of biological agents which would
likely be used as weapons are bacteria, viruses, and toxins.
1. Bacteria. Bacteria are small free-living organisms that reproduce by simple
division and are easy to grow. The diseases they produce often respond to treatment
with antibiotics.
2. Viruses. Viruses are organisms which require living cells in which to reproduce
and are intimately dependent upon the body they infect. Viruses produce diseases
which generally do not respond to antibiotics. However, antiviral drugs are
sometimes effective.
3. Toxins. Toxins are poisonous substances found in, and extracted from, living
plants, animals, or microorganisms; some toxins can be produced or altered by
chemical means. Some toxins can be treated with specific antitoxins and selected
drugs. Most biological agents are difficult to grow and maintain. Many break
down quickly when exposed to sunlight and other environmental factors, while
others such as anthrax spores are very long lived. They can be dispersed by
spraying them in the air, or infecting animals which carry the disease to humans
as well through food and water contamination.
AerosolsBiological agents are dispersed into the air, forming a
fine mist that may drift for miles. Inhaling the agent may cause disease in
people or animals.
AnimalsSome diseases are spread by insects and animals, such as
fleas, mice, flies, and mosquitoes. Deliberately spreading diseases through
livestock is also
referred to as agroterrorism.
Food and water contamination
Some pathogenic organisms and toxins may persist in food and water supplies.
Most microbes can be killed, and toxins deactivated, by cooking food and boiling
water. Anthrax spores formulated as a white powder were mailed to individuals
in the government and media in the fall of 2001. Postal sorting machines and
the opening of letters dispersed the spores as aerosols. Several deaths resulted.
The effect was to disrupt mail service and to cause a widespread fear of handling
delivered mail among the public. Person-to-person spread of a few infectious
agents is also possible. Humans have been the source of infection for smallpox,
plague, and the Lassa viruses Be aware of your surroundings. The very nature
of terrorism suggests that there may be little or no warning.
What to do to prepare for a chemical or biological attack
Assemble a disaster supply kit (see the Emergency Planning and
Disaster Supplies chapter for more information) and be sure to include:
Battery-powered commercial radio with extra batteries.
Non-perishable food and drinking water.
Roll of duct tape and scissors.
Plastic for doors, windows and vents for the room in which you will shelter
in placethis should be an internal room where you can block out air that
may
contain hazardous chemical or biological agents. To save critical time during
an emergency, sheeting should be pre-measured and cut for each opening.
First aid kit.
Sanitation supplies including soap, water and bleach.
What to do during a chemical or biological attack
1. Listen to your radio for instructions from authorities such as whether to
remain inside or to evacuate.
2. If you are instructed to remain in your home, the building where you are,
or other shelter during a chemical or biological attack:
Turn off all ventilation, including furnaces, air conditioners, vents
and fans.
Seek shelter in an internal room, preferably one without windows. Seal
the room with duct tape and plastic sheeting. Ten square feet of
floor space per person will provide sufficient air to prevent carbon dioxide
build-up for up to five hours. (See Shelter chapter.)
Remain in protected areas where toxic vapors are reduced or eliminated,
and be sure to take your battery-operated radio with you.
3. If you are caught in an unprotected area, you should:
Attempt to get up-wind of the contaminated area.
Attempt to find shelter as quickly as possible.
Listen to your radio for official instructions.
What to do after a chemical attack
Immediate symptoms of exposure to chemical agents may include blurred vision,
eye irritation, difficulty breathing and nausea. A person affected by a chemical
or biological agent requires immediate attention by professional medical personnel.
If medical help is not immediately available, decontaminate yourself and assist
in
decontaminating others. Decontamination is needed within minutes of exposure
to minimize health consequences. (However, you should not leave the safety of
a shelter to go outdoors to help others until authorities announce it is safe
to do so.)
The best protection against a chemical or biological attack would come from
being prepared and getting quick medical attention.
1. Use extreme caution when helping others who have been exposed to chemical
agents:
Remove all clothing and other items in contact with the body.
Contaminated clothing normally removed over the head should be cut off to avoid
contact with the eyes, nose, and mouth. Put into a plastic bag if possible.
Decontaminate hands using soap and water. Remove eyeglasses or contact lenses.
Put glasses in a pan of household bleach to decontaminate.
2. Remove all items in contact with the body.
3. Flush eyes with lots of water.
4. Gently wash face and hair with soap and water; then thoroughly rinse with
water.
5. Decontaminate other body areas likely to have been contaminated. Blot (do
not swab or scrape) with a cloth soaked in soapy water and rinse with
clear water.
6. Change into uncontaminated clothes. Clothing stored in drawers or closets
is likely to be uncontaminated.
7. If possible, proceed to a medical facility for screening.
What to do after a biological attack In many biological attacks, people will
not know they have been exposed to an agent. In such situations, the first evidence
of
an attack may be when you notice symptoms of the disease caused by an agent
exposure, and you should seek immediate medical attention for treatment. In
some situations, like the anthrax letters sent in 2001, people may be alerted
to a potential exposure. If this is the case, pay close attention to all official
warnings and instructions on how to proceed. The delivery of medical services
for a biological event may be handled differently to respond to increased demand.
Again, it will be important for you to pay attention to official instructions
via radio, television, and emergency alert systems. If your skin or clothing
comes in contact with a visible, potentially infectious substance, you should
remove and bag your clothes and personal items and wash yourself with warm soapy
water immediately. Put on clean clothes and seek medical assistance. For more
information, visit the website for the Centers for Disease Control and Prevention,
www.bt.cdc.gov.
Nuclear and Radiological Attack
Nuclear explosions can cause deadly effectsblinding light, intense heat
(thermal radiation), initial nuclear radiation, blast, fires started by the
heat pulse, and secondary fires caused by the destruction. They also produce
radioactive particles called fallout that can be carried by wind for hundreds
of miles. Terrorist use of a radiological dispersion device (RDD)often
called dirty nuke or dirty bombis considered far
more likely than use of a nuclear device. These radiological weapons are a combination
of conventional explosives and radio- active material designed to scatter dangerous
and sub-lethal amounts of radioactive material over a general area. Such radiological
weapons appeal to terrorists because they require very little technical knowledge
to build and deploy compared to that of a nuclear device. Also, these radioactive
materials, used widely in medicine, agriculture, industry and research, are
much more readily available and easy to obtain compared to weapons grade uranium
or plutonium.
Terrorist use of a nuclear device would probably be limited to a single smaller
suitcase weapon. The strength of such a weapon would be in the range
of the
bombs used during World War II. The nature of the effects would be the same
as a weapon delivered by an inter-continental missile, but the area and severity
of the
effects would be significantly more limited. There is no way of knowing how
much warning time there would be before an attack by a terrorist using a nuclear
or radiological weapon. A surprise attack remains a possibility. The danger
of a massive strategic nuclear attack on the United States involving many weapons
receded
with the end of the Cold War. However, some terrorists have been supported by
nations that have nuclear weapons programs. If there were threat of an attack
from a hostile nation, people living near potential targets could be advised
to evacuate or they could decide on their own to evacuate to an area not considered
a likely target. Protection from radioactive fallout would require taking shelter
in an underground area, or in the middle of a large building. In general, potential
targets include:
Strategic missile sites and military bases.
Centers of government such as Washington, D.C., and state capitals.
Important transportation and communication centers.
Manufacturing, industrial, technology and financial centers.
Petroleum refineries, electrical power plants and chemical plants.
Major ports and airfields.
Taking shelter during a nuclear attack is absolutely necessary. There are two
kinds of sheltersblast and fallout Blast shelters offer some protection
against blast pressure, initial radiation, heat and fire, but even a blast shelter
could not withstand a direct hit from a nuclear detonation. Fallout shelters
do not need to be specially
constructed for that purpose. They can be any protected space, provided that
the walls and roof are thick and dense enough to absorb the radiation given
off by fallout
particles. The three protective factors of a fallout shelter are shielding,
distance, and time.
Shielding. The more heavy, dense materialsthick walls, concrete,
bricks, books and earthbetween you and the fallout particles, the better.
Distance. The more distance between you and the fallout particles, the
better. An underground area, such as a home or office building basement, offers
more protection than the first floor of a building. A floor near the middle
of a high-rise may be better, depending on what is nearby at that level on which
significant fallout particles would collect. Flat roofs collect fallout particles
so the top floor is not a good choice, nor is a floor adjacent to a neighboring
flat roof.
Time. Fallout radiation loses its intensity fairly rapidly. In time,
you will be able to leave the fallout shelter. Radioactive fallout poses the
greatest threat to people during the first two weeks, by which time it has declined
to about 1% of its initial radiation level.
Remember that any protection, however temporary, is better than none at all,
and the more shielding, distance and time you can take advantage of, the better.
Most electronic equipment within 1,000 miles of a highaltitude nuclear detonation
could be damaged by EMP.
Electromagnetic pulse
In addition to other effects, a nuclear weapon detonated in or above the earths
atmosphere can create an electromagnetic pulse (EMP), a high-density electrical
field.
EMP acts like a stroke of lightning but is stronger, faster and briefer. EMP
can seriously damage electronic devices connected to power sources or antennas.
This include communication systems, computers, electrical appliances, and automobile
or aircraft ignition systems. The damage could range from a minor interruption
to actual burnout of components. Most electronic equipment within 1,000 miles
of a high-altitude nuclear detonation could be affected. Battery powered radios
with
short antennas generally would not be affected. Although EMP is unlikely to
harm most people, it could harm those with pacemakers or other implanted electronic
devices.
What to do before a nuclear or radiological attack
1. Learn the warning signals and all sources of warning used in your community.
Make sure you know what the signals are, what they mean, how they will be used,
and what you should do if you hear them.
2. Assemble and maintain a disaster supply kit with food, water, medications,
fuel and personal items adequate for up to 2 weeksthe more the better.
(See the Emergency Planning and Disaster Supplies chapter for more
information).
3. Find out what public buildings in your community may have been designated
as fallout shelters. It may have been years ago, but start there, and learn
which buildings are still in use and could be designated as shelters again.
Call your local emergency management office.
Look for yellow and black fallout shelter signs on public buildings.
Note: With the end of the Cold War, many of the signs have been removed from
the buildings previously designated.
If no noticeable or official designations have been made, make your own
list of potential shelters near your home, workplace and school: basements,
or the windowless center area of middle floors in high-rise buildings, as well
as subways and tunnels.
Give your household clear instructions about where fallout shelters are
located and what actions to take in case of attack.
4. If you live in an apartment building or high-rise, talk to the manager about
the safest place in the building for sheltering, and about providing for building
occupants until it is safe to go out.
5. There are few public shelters in many suburban and rural areas. If you are
considering building a fallout shelter at home, keep the following in mind.
A basement, or any underground area, is the best place to shelter from
fallout. Often, few major changes are needed, especially if the structure has
two or more stories and its basement or one corner of itis below
ground.
Fallout shelters can be used for storage during non-emergency periods,
but only store things there that can be very quickly removed. (When they are
removed, dense, heavy items may be used to add to the
shielding.)
See the Tornadoes section in the Thunderstorms chapter
for information on the Wind Safe Room, which could be used as shelter
in the event of a nuclear detonation or for fallout protection, especially in
a home without a basement.
All the items you will need for your stay need not be stocked inside
the shelter itself but can be stored elsewhere, as long as you can move them
quickly to the shelter.
6. Learn about your communitys evacuation plans. Such plans may include
evacuation routes, relocation sites, how the public will be notified and transportation
options for people who do not own cars and those who have special needs. See
the Evacuation chapter for more information.
7. Acquire other emergency preparedness booklets that you may need. See the
For More Information chapter at the end of this guide.
What to do during a nuclear or radiological attack
1. Do not look at the flash or firebal it can blind you.
2. If you hear an attack warning:
Take cover as quickly as you can, BELOW GROUND IF POSSIBLE, and stay
there unless instructed to do otherwise.
If you are caught outside, unable to get inside immediately, take cover
behind anything that might offer protection. Lie flat on the ground and cover
your head.
If the explosion is some distance away, it could take 30 seconds or more
for the blast wave to hit.
3. Protect yourself from radioactive fallout.
If you are close enough to see the brilliant flash of a nuclear explosion, the
fallout will arrive in about 20 minutes. Take shelter, even if you are many
miles from ground zeroradioactive fallout can be carried by the winds
for hundreds of miles. Remember the three protective factors: shielding, distance
and time.
4. Keep a battery-powered radio with you, and listen for official information.
Follow the instructions given. Local instructions should always take precedence:
officials on the ground know the local situation best.
What to do after a nuclear or radiological attack
In a public or home shelter:
1. Do not leave the shelter until officials say it is safe. Follow their instructions
when leaving.
2. If in a fallout shelter, stay in your shelter until local authorities tell
you it is permissible or advisable to leave. The length of your stay can range
from a day or two to four weeks.
Contamination from a radiological dispersion device could affect a wide
area, depending on the amount of conventional explosives used, the quantity
of radioactive material and atmospheric conditions.
A suitcase terrorist nuclear device detonated at or near
ground level would produce heavy fallout from the dirt and debris sucked up
into the mushroom cloud.
A missile-delivered nuclear weapon from a hostile nation would probably
cause an explosion many times more powerful than a suitcase bomb, and provide
a greater cloud of radioactive fallout.
The decay rate of the radioactive fallout would be the same, making it
necessary for those in the areas with highest radiation levels to remain in
shelter for up to a month.
The heaviest fallout would be limited to the area at or downwind from
the explosion, and 80% of the fallout would occur during the first 24 hours.
Because of these facts and the very limited number of weapons terrorists
could detonate, most of the country would not be affected by fallout(USA).
People in most of the areas that would be affected could be allowed to
come out of shelter and, if necessary, evacuate to unaffected areas within a
few days.
3. Although it may be difficult, make every effort to maintain sanitary conditions
in your shelter space.
4. Water and food may be scarce. Use them prudently but do not impose severe
rationing, especially for children, the ill or elderly.
5. Cooperate with shelter managers. Living with many people in confined space
can be difficult and unpleasant.
Returning to your home
1. Keep listening to the radio for news about what to do, where to go, and places
to avoid.
2. If your home was within the range of a bombs shock wave, or you live
in a high-rise or other apartment building that experienced a non-nuclear Learn
how
to build a temporary fallout shelter to protect yourself from radioactive fallout
even if you do not live near a potential nuclear target. explosion, check first
for any sign of
collapse or damage, such as:
toppling chimneys, falling bricks, collapsing walls, plaster falling
from ceilings.
fallen light fixtures, pictures and mirrors.
broken glass from windows.
overturned bookcases, wall units or other fixtures.
fires from broken chimneys.
ruptured gas and electric lines.
3. Immediately clean up spilled medicines, drugs, flammable liquids, and other
potentially hazardous materials.
4. Listen to your battery-powered radio for instructions and information about
community services.
5. Monitor the radio and your television for information on assistance that
may be provided. Local, state and federal governments and other organizations
will help meet
emergency needs and help you recover from damage and losses.
6. The danger may be aggravated by broken water mains and fallen power lines.
7. If you turned gas, water and electricity off at the main valves and switch
before you went to shelter:
Do not turn the gas back on.
The gas company will turn it back on for you or you will receive other instructions.
Turn the water back on at the main valve only after you know the water
system is working and water is not contaminated.
Turn electricity back on at the main switch only after you know the wiring
is undamaged in your home and the community electrical system is functioning.
Check to see that sewage lines are intact before using sanitary facilities.
8. Stay away from damaged areas.
9. Stay away from areas marked radiation hazard or HAZMAT.

Red, Orange, Yellow,
Blue, Green
Although the Homeland Security Advisory System is binding on the executive branch,
it is voluntary to other levels of government and the private sector. There
are five threat conditions, each identified by a description and corresponding
color. The greater the risk of a terrorist attack, the higher the threat condition.
Risk
includes both the probability of an attack occurring and its potential gravity.
Homeland Security Advisory System
The Homeland Security Advisory System was designed to provide a comprehensive
means to disseminate information regarding the risk of terrorist acts to federal,
state, and local authorities and to the American people. This system provides
warnings in the form of a set of graduated Threat Conditions that
increase as the risk of the threat increases. At each threat condition, federal
departments and agencies would implement a corresponding set of Protective
Measures to further reduce vulnerability or increase response capability
during a period of heightened alert Threat conditions are assigned by the Attorney
General in consultation with the Assistant to the President for Homeland Security.
Threat conditions may be assigned for the entire nation, or they may be set
for a particular geographic area or industrial sector. Assigned threat conditions
will be reviewed at regular intervals to determine whether adjustments are warranted.
Threat Conditions and Associated Protective Measures
There is always a risk of a terrorist threat. Each threat condition assigns
a level of alert appropriate to the increasing risk of terrorist attacks. Beneath
each threat condition are some suggested protective measures that the government
and the public can take, recognizing that the heads of federal departments and
agencies are responsible for developing and implementing appropriate agencyspecific
Protective Measures:
Low Condition (Green). This condition is declared
when there is a low risk of terrorist attacks. Federal departments and agencies
will consider the following protective measures.
Refine and exercise prearranged protective measures;
Ensure personnel receive proper training on the Homeland Security Advisory
System and specific prearranged department or agency protective measures; and
Institute a process to assure that all facilities and regulated sectors
are regularly assessed for vulnerabilities to terrorist attacks, and all reasonable
measures are taken to mitigate these vulnerabilities.
Members of the public can:
Develop a household disaster plan and assemble a disaster supply kit.
(see Emergency Planning and Disaster Supplies chapter).
Guarded Condition (Blue). This condition is declared
when there is a general risk of terrorist attacks. In addition to the measures
taken in the previous threat condition, federal departments and agencies will
consider the following protective measures:
Check communications with designated emergency response or command locations;
Review and update emergency response procedures; and
Provide the public with any information that would strengthen its ability
to act appropriately.
Members of the public, in addition to the actions taken for the previous threat
condition, can:
Update their disaster supply kit;
Review their household disaster plan;
Hold a household meeting to discuss what members would do and how they
would communicate in the event of an incident;
Develop a more detailed household communication plan;
Apartment residents should discuss with building managers steps to be
taken during an emergency; and
People with special needs should discuss their emergency plans with friends,
family or employers.
Elevated Condition (Yellow). An Elevated Condition
is declared when there is a significant risk of terrorist attacks. In addition
to the measures taken in the previous
threat conditions, federal departments and agencies will consider the following
protective measures:
Increase surveillance of critical locations;
Coordinate emergency plans with nearby jurisdictions as appropriate;
Assess whether the precise characteristics of the threat require the
further refinement of prearranged protective measures; and
Implement, as appropriate, contingency and emergency response plans.
Members of the public, in addition to the actions taken for the previous threat
condition, can:
Be observant of any suspicious activity and report it to authorities;
Contact neighbors to discuss their plans and needs;
Check with school officials to determine their plans for an emergency
and procedures to reunite children with parents and caregivers; and
Update the household communication plan.
High Condition (Orange). A High Condition is declared when there is a
high risk of terrorist attacks. In addition to the measures taken in the previous
threat
conditions, federal departments and agencies will consider the following protective
measures:
Coordinate necessary security efforts with federal, state, and local
law enforcement agencies, National Guard or other security and armed forces;
Take additional precautions at public events, possibly considering alternative
venues or even cancellation;
Prepare to execute contingency procedures, such as moving to an alternate
site or dispersing the workforce; and
Restrict access to a threatened facility to essential personnel only.
Members of the public, in addition to the actions taken for the previous threat
conditions, can:
Review preparedness measures (including evacuation and sheltering) for
potential terrorist actions including chemical, biological, and radiological
attacks;
Avoid high profile or symbolic locations; and
Exercise caution when traveling.
Severe Condition (Red). A Severe Condition reflects
a severe risk of terrorist attacks. Under most circumstances, the protective
measures for a Severe Condition
are not intended to be sustained for substantial periods of time. In addition
to the protective measures in the previous threat conditions, federal departments
and agencies also will consider the following general measures:
Increase or redirect personnel to address critical emergency needs;
Assign emergency response personnel and pre-position and mobilize specially
trained teams or resources;
Monitor, redirect, or constrain transportation systems; and
Close public and government facilities not critical for continuity of
essential operations, especially pubic safety.
Members of the public, in addition to the actions taken for the previous threat
conditions, can:
Avoid public gathering places such as sports arenas, holiday gatherings,
or other high risk locations;
Follow official instructions about restrictions to normal activities;
Contact employer to determine status of work;
Listen to the radio and TV for possible advisories or warnings; and
Prepare to take protective actions such as sheltering-in-place or evacuation
if instructed to do so by public officials.
