Positive Mental AttitudePositive Mental AttitudeSituational awareness, basic knowledge and a “survivor’s mindset” enable you to cope effectively STOP STOP
– Calm down, and size up your situation… THINKTHINK
– Anticipate which hazards are most likely– Take stock of materials and resources around you
OBSERVEOBSERVE – Orient yourself to your surroundingsOrient yourself to your surroundings
PLANPLAN – Select equipment and supplies appropriatelySelect equipment and supplies appropriately
ACT!ACT! – Execute the plan, evaluate progress, adjust, go on. Execute the plan, evaluate progress, adjust, go on.

DISASTER PREPAREDNESS
Have an evacuation kit ready at all times
• Don't presume that a disaster will be short-term • Pack essentials first, then consider comfort items• In real emergences, forget last-minute purchases• Plan for more supplies than you “think” you may need • Inspect / renew your supplies each spring and fall• Provide entertainment for young children.
6
WHEN “IT” HITS THE FAN”
Use these six steps in problem solving Size Up ...your Situation Determine... Objectives (stay or evacuate?) Identify ...Resources (either stored supplies
or salvaged materials from your surroundings)
Evaluate …Options (use the safest way) Build ...an action Plan (use your head) Take ...Action
– re-evaluate your action plan, adapt, improvise and overcome!
7
FIRST AID AND SANITATION
Maintain personal and family health– Prompt treatment reduces infection risk– Sanitation reduces risk of disease vectors
– Water borne illnesses, diarrhea
Major cause of dehydration Increases your survivability!
8
Disaster Injury Risk Factors
Tool / equipment hazards, risk of hand, eye, head injuries, electric shock, chemical burns
Human factors, stress / fatigue Structural instability
– Trauma risk, falls, building collapse potential Terrain, loose rock, fallen limbs, wet or
insecure footing, risk of falls, puncture wounds and lacerations from debris.
9
Disaster Contamination
Stagnant surface water– Mosquito breeding
Contaminated flood waters– Sewage treatment system overflow– Petroleum, industrial, agricultural
chemical contamination Airborne contaminant plumes
– Smoke, dust, toxic gases, – or radioactive fallout.

DO NOT occupy a floor that has been flooded, mold grows fastDO NOT occupy a floor that has been flooded, mold grows fast!!
EVACUATION PLANNING
• It’s usually best to relocate with friends or relatives who live outside of the affected area
• Don't rely on government-run shelters• They are an “option of last resort” for those unable to evacuate
• Evacuation route selection is important• Make sure your vehicle can carry essentials
• A huge “bug-out” vehicle is a handicap on crowded roads• It uses more fuel, which may be expensive / scarce in an emergency.
• Don't plan on fuel being available en route• In normal times always keep your gas tank at least half full• Upon warning an event is imminent, conserve fuel, keep tank ¾ full• Carry extra fuel containers outside the vehicle

FROM NATIONAL THREAT SCENARIO
Nuclear Detonation – 10-Kiloton Improvised Nuclear Device
http://iis-db.stanford.edu/pubs/21872/DayAfterWorkshopReport.pdf An attack may:•be single or up to a dozen detonations
- on specific or random targets.•be an act of a non-state
-, i.e. a terrorist group such as Al Qaeda.•be threatened to trigger a political result,
- bend will of the people.•involve either a detonation (fission/fusion)
- or release via a Radiological Dispersal Device (RDD) •occur all in one attack
– or recur over a period of weeks, months, years.
LOW YIELD WEAPON EFECTS Contamination from a Radiological Dispersal
Device (RDD) would cover up to a few hundred acres with low-level radioactive material;
http://www.bt.cdc.gov/radiation/pdf/dirtybombs.pdf A nuclear detonation would affect large areas
(10-100 sq. miles) damaged by direct effects and 100s to 1,000s of sq. miles with radioactive fallout.http://www.nti.org/e_research/cnwm/overview/technical3.asp?print=true
Electromagnetic Pulse (EMP) – a terrorist attack would most likely be a small device <10 kilotons yield, EMP effect of a ground burst would be mostly within the Moderate Damage Radius, but also propagated by conductors such as power and telephone lines, railroad tracks, pipelines, etc. http://en.wikipedia.org/wiki/Electromagnetic_pulse
EMP Precautions Disconnect electronics from conductors
(AC mains and antennas) Store small solid-state electronics
having Field Effect Transistors (FET) or other integrated circuits (IC) in a Faraday Cage (an unplugged microwave oven)
Construct EMP-resistant containers constructed with a continuously sealed metal barrier (foil covered cardboard boxes)
Most susceptible to EMP damage are automobiles with onboard "computers" which control essential functions.
EVACUATION
Feasible only if all personnel can evacuate before fallout contamination arrives and;
Essential functions for Continuity of Operations are transferred to an alternate facility
Affected area would have to be small and warning time adequate to execute the evacuation
Detonation effects (blast/thermal/EMP) will likely impede evacuation
Evacuees may be exposed and/or contaminated.
Evacuate or Stay Decision?Conclusion from FEMA Urban-Rural Evacuation State Planners Workshop Sept. 2006
Given ● Population of the DC Metro area● Propensity to self-evacuate, overwhelmingly
by automobile● Wide distribution of evacuation destinations,● Perceived vulnerability to terror attack,
and anticipation of multiple attacks
Result: ● A large-scale, chaotic mass self-evacuation should be anticipated.
SHELTER IN PLACE Critical facilities that cannot evacuate (hospitals,
EOCs) must continue to operate Necessary if fallout/contamination would arrive
before evacuation can be completed Fallout Shelters will be needed to protect against
high level radiation/detonation Shelter-in-place (not necessarily Fallout Shelter)
near RDD/very low level Shelter stay may range from a few days to 2
weeks. Authorities outside affected area can organize
rescue/evacuation effort Shelter occupants may be exposed and/or
contaminated.
SHELTER IN PLACE
Necessary if operations can not be transferred or if staff, patients or clients cannot evacuate
Necessary if needed to support operations of other response agencies
Must have Radiological Monitoring & Exposure Control capabilities
Critical Facilities may be used to shelter families of the staff
Critical Facilities will not be used to shelter the general public.
DECONTAMINATION after a flood or attackStart immediately, even if you don’t know what the agent is. Sandia decontamination foam (US Patent 6,566,574 B1) sold as Scott's Liquid Gold Mold Control 500 in hardware stores.
Is effective against most chemical and biological agents, including nerve, blister, anthrax, SARS, Norwalk, avian and common flu.
Widely used for hospital /hotel sanitization mold remediation in commercial buildings, cleaning / neutralizing agricultural sprayers.
Moderate cost, about $30 at Home Depot.

EXPEDIENT FIELD DECONTAMINATIONEXPEDIENT FIELD DECONTAMINATIONif you are contaminated:if you are contaminated: Remove everything, including jewelry Cut off clothing normally removed over the head Place contaminated clothing in plastic bag, tie closed Wash your hands before using them to shower Flush entire body with cool water Blot dry with absorbent cloth Put on clean clothes Avoid use of affected areas, to prevent re-exposure If professional help arrives, report to responders for
thorough decontamination and medical assessment.
NUCLEAR ATTACK ISSUES
Structural damage to shelter from nearby detonation
Fire in the shelter Dangerously high radiation levels Severely high temperatures and
humidity Oxygen and Carbon Dioxide imbalance
in the shelter Depletion of essential supplies Disease and injury Unrest, anxiety, crime or defiance of
order or authority
Substantial barriers offer best protection
Time - Fallout radiation intensity decays rapidly;90% in just the first 7 hours. The less time you spend in a radiation field, the less dose received.
Distance - The farther you are from a source, the less dose you receive.
Shielding - Denser (heavier, massive) materials absorb more radiation. Greater thickness of any given material absorbs more radiation.

Outside radiation, divided by the Protection Factor, is reduced in proportion. For example, if the outside radiation rate is 1,000 R/hr, a person shielded by 3 ft. of earth would receive a dose rate of .5 R/hr. but a person shielded by 1 ft of earth would receive about 10 R/hr.
*PF = “Protection Factor” refers to the ratio between the radiation dose rate of the OUTSIDE to that INSIDE the shelter, for instance a PF = 10 means that the inside dose rate is 1/10th the outside rate.
IMPROVE HOME FALLOUT PROTECTION
Increase shielding by:1) Plan / improvise vents, ventilation & 2
entrances. 2) Add wooden shoring supports below each
story.3) Add up to 12” maximum dirt on upper
floors/roof. 4) Cover window opening with plywood
sheeting.5) Pile dirt to ceiling height along outside
walls & windows.
Sheltering at Home During an Emergency
For using a building without working utilities as shelter Exhaust – candles, camp stoves,
lanterns, generators, heaters, charcoal grills, all generate carbon monoxide and must not be used indoors!
Open flame – above ignition sources must never be left unattended!
Fuel – most of the above require flammable fuels to operate, which must be stored outdoors.– Use Fire Marshal approved fuel
containers
14
Generator Safety Tips Generator Safety Tips From the U.S. Consumer Product Safety Commission
Carbon monoxideCarbon monoxide hazard! hazard! – Never use indoors or in attached garages!– Set up OUTDOORS in well ventilated, dry area– Away from open windows or HVAC air intakes– Under a canopy, open shed or carport
ElectrocutionElectrocution Hazard! Hazard!– Ground both the generator and equipment!– Plug only individual devices into generator
– DO NOT connect into household AC!– UL-rated cords of gage adequate for load
Explosion / fire hazardExplosion / fire hazard!!– Fuel vapors traveling along the ground can be ignited
by switching equipment or appliance pilot lights!
http://www.cpsc.gov/cpscpub/pubs/portgen.pdf
Improvised Emergency SheltersAs in all real estate, most important is location: Avoid low spots with poor drainage Seek a gently sloped area so that
surface water drains away Sheltered from prevailing winds Away from bodies of water (attracts
insects and animals) Insulated from direct contact with
ground, rock, or concrete, which conducts away body heat.
15
Avoid as shelter Areas around
downed utility lines In or near culverts Within the
“collapse zone” of a damaged building – (maintain 2:1 ratio of
distance away to building height)
16
Improvised Shelters
Sheds Tents Tarps Vehicles
17
Don’t disable a good car! Remove car batteries to power
communications and shelter lighting only from cars that do not start – If a car starts reserve it for emergency
evacuation, or– Use it as a “battery charger” – Salvage lighting, remove dome lights, tail lights,
trunk lights, etc. & with at least 36” of wires.– Position batteries in shelter; attach wires & lights– As batteries discharge, replace with new batteries
or recharge batteries.
Emergency Shelter MaterialsSalvage building materials from debris or from damaged structures only when it can be done safely
TYVEK building wrap Plastic sheeting Roofing paper and shingles Siding, plywood Chain link fence Lumber Carpeting Wire, rope, and fasteners
18
Build Your Shelter In Layers
Structural framing, lumber, plywood, fencing, metal Fasteners, reinforce structural connections with
nails, wire or rope ties, wooden spikes Water and wind proofing, TYVEK, plastic sheeting,
tarp, shingles, roofing paper Insulation, drywall, leaves, tree branches, carpeting,
(may also be used as ballast to hold water/wind proofing layer in place)
19
SIGNALLING Day
– Mirror flashes – best daylight signal device– Smoke– Brightly colored cloth flag / panel (VS-17)– ICAO surface-to-air signals
Night– Flashing strobe light– Fire– Signal flares
Sound – Whistle, vehicle horn

http://www.bestglide.com/VS17_Signal_Panel.html
Signal Mirror Simple, inexpensive, effective Doesn’t rely on batteries or
pyrotechnics Visible from 5 to 10 miles in
daylight
21
FIRE
Maintains body temperature Great morale booster Deters wild animals and insects Boils water Cooks food Used as day (smoke) or night (light) signal
22
Fire making methods
Matches or lighter Flint and steel
– Use cotton ball and petroleum jelly as tinder
Battery and steel wool Burning lens
23http://www.ehow.com/how_18193_make-fire-starters.html
WATER Minimum for drinking
– 1 gallon per person, per day More water is needed for
– Cooking and food preparation– Personal hygiene, sanitation and
decontamination Store a two week supply as minimum
– Food grade containers with screw caps– Away from direct sunlight
24
Emergency Water Sources
Captive water in household hot water tank and interior plumbing is OK
Filter cloudy water to remove particulates, using an EPA-rated filter with a pore size ≤ 1 micron, then:
Disinfect with Clorox (6% sodium hypochlorite) add 8 drops of bleach per gallon if clear, 16 drops if cloudy, let water stand 15 minutes before use
Or boil vigorously for 15 minutes Store potable water in clean containers.
25
All surface water is contaminated!
All natural sources (from springs, ponds, rivers or streams) must be boiled or chemically disinfected.
Chemical disinfection or boiling – Kills bacteria and viruses– Doesn’t remove particulates or chemical pollutants
Filtration– Coffee filters, etc. remove gross particulates only– EPA-rated filters (pore size is smaller than 1 micron) are
needed to remove bacteria, viruses and Giardia cysts, but don’t remove chemical pollutants.
Distillation is the most effective method.
26
FOOD
Lowest of the seven survival priorities Need is mostly mental, because we
are used to eating regularly Healthy people will do OK without
food for a week or more, if they are well hydrated
Balanced nutrition is a more important health factor for elderly and infants.
27
Shelf life of foods stored in the home Food in a refrigerator is safe for a day after the power goes off,
either use it in 24 hours or throw it away Frozen food is safe if there are still ice crystals, once thawed,
cook and consume it within 24 hours Next use non-perishables and dry staples Canned foods are best for long term storage (up to 4 years) but
are heavy to transport and bulky to store Dry packaged foods are easiest to transport Choose foods requiring minimal preparation Eat at least one balanced meal daily Include nutritional supplements in supplies Drink enough water.
28
Emergency Food supplies
MREs, or Heater Meals® Prepared survival rations Primitive survival methods:
– Fishing– Hunting– Trapping– Foraging
29
TOOLS and EQUIPMENT Folding utility knife or multi-
tool– Scout type, Leatherman®, Swiss Army or Mil-K-
818 Manual can opener Sturdy fixed blade
– For chopping, digging, or as pry bar Shovel Hand saw Axe

31
DISASTER FINANCIAL PLANNING Electronic transactions, account
verifications may be impossible Evacuate with enough cash for at
least two weeks of essentials Carry account numbers, contact
addresses and telephone numbers for all important persons and institutions
Helping one's unprepared friends and neighbors may prove expensive!

SOCIAL IMPLICATIONS OF DISASTERS
Cumulative psychological effects upon survivors Evacuate or Stay? – Do you have a plan? Where will you go? Is it safe to travel? Can you REALLY get there? Do
you have enough resources to make it work? Warn friends not to invite others to come and evacuate
with them– They’ll overwhelm your limited resources!
Never allow family members to be separated– Even if it means waiting for later rescue and/or evacuation
The well prepared may be threatened by those who weren't – get to know your neighbors NOW for a safer community later in case of a disaster– Make plans to ensure neighborhood security/family protection– Post a guard in rotating shifts, to deter roving criminals or looters – Keep firearms and ammunition safely secured – Take a home firearms safety-protection course
33
Lessons from Hurricane KatrinaWhen help arrives, you may get it “…….whether you want it or not.”
Don't believe that all rescuers will respect your property
Relief workers from other States often don't know local laws
Relief organizations have their own bureaucratic requirements that may conflict with your needs
Expect frustration over lack of communication and empathy by rescuers and local/State government.
