    This is what we teach our employees:

    Disaster V. Catastrophe
    Disasters are short term - “Make do for 3-4 days until help arrives…”
    Catastrophic events are long term
    Katrina-scale hurricane, tsunami, earthquake
    Major terror attack, nuclear detonation, dirty bomb
    No help is coming soon, “you are on your own”

    Why?
    Complete loss of civil infrastructure
    Minimal or no police, fire or EMS response
    No electricity, municipal water, communications
    Transport of fuel / food is severely impaired
    Public safety agencies will be overwhelmed
    Recovery is long term (over 30 days)

    [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.

    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)
    Plan (use your head)
    Act...Improvise and overcome

    SHELTER Protection from the elements
    Wind and rain resistant
    Insulation from cold

    “Stay or Evacuate” Decision
    If evacuation is not mandatory, the same safety rules
    for entering a structure apply to using your home as shelter

    EVACUATE OR STAY?
    Conclusion from FEMA Urban-Rural Evacuation State Planners Workshop

    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.

    DO NOT OCCUPY IF:
    There is structural damage
    (6 sides of the “box” are not plumb)
    Utilities cannot be controlled
    Structure was damaged in a fire
    DO NOT occupy a floor that has been flooded,
    micotoxins from molds are respiratory hazard!

    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? – 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

    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 - Continued
    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 attack start 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.

    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 to treat 500sf.

    Sandia decon formulation, best known as an anthrax killer, takes on household mold - April 26, 2007

    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

    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.

    Protection Factors & Mass of Materials
    *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.

    How Much Protection?

    PF* Lead Steel Concrete Earth Water Wood
    2 .3"" .7" 2.0" 3.3" 5" 9"
    4 .5" 1.5" 5.0" 7.0" 10" 15"
    8 1.0" 2.0" 6.5" 10.0" 15" 27"
    16 1.2" 3.0" 9.0" 14.0" 20" 3 ft
    32 1.5" 4.0" 12.0" 15.0" 2 ft 4 ft
    64 2.0" 4.2" 13.2" 19.8" 2.5ft 4.5 ft
    128 2.1" 5.0" 15.0" 2 ft 3 ft 5 ft
    1000 3.0" 7.0" 22.0" 33.0" 4 ft -
    2000 3.3" 7.7" 2 ft 3 ft 4.5 ft -

    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.

    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

    Improvised Emergency Shelters
    As 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.

    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)

    Improvised Shelters:
    Sheds
    Tents
    Tarps
    Vehicles

    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 Materials:
    Salvage 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

    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)

    That's great your local Government's has that position. We don't. Do you find most other counties do?

    Dept. of Defense Capitol Shield Exercise Oct. 27

    Around the Washington, DC area it's the standing policy. We are in the terrorist "bullseye." Many preparations are low-key, take place behind the scenes and don't get much publicity, but our plans get evaluated regularly in exercises such as Capitol Shield which takes place on Monday Oct. 27th.

    Below is a link to a story from last year's exercise; this will give you an idea of what this exercise is, what it is designed to do, how it is conducted and how important the role of volunteer victim is to the exercise planners.

    'Capital Shield' Propels NCR into Response Mode

    This year's exercise is scheduled to take place at the old DC Dept. of Corrections prison site in Lorton. The following is a tentative timeline for the day's events.

    Our volunteers in Fairfax County CERT act as role players and then after being rescued, transition into becoming responders on Monday, 27 October.

    October 27th, 2008 – Capital Shield Exercise-Lorton prison site.

    0530 – moulage starts with support from Walter Reed Army medical center.

    0700 – Exercise Starts

    0710 – all role players are placed into the exercise scene

    Approx. 1200 – after being rescued, CERTs will transition into responder activities.

    Approx. 1730 – 1900 – CERT volunteer response ends. DoD and public safety personnel continue into the night.

    This full scale exercise starts at 5:30 AM. It will be an early start to an excitement filled day for our volunteers. They need to wear clothes that can be torn, dirtied and stained-after all they are portraying incident victims. Details and instructions are be sent out in the participant briefing email.

    This gives our CERT a chance to see what they are learning in class being put into action. Working side-by-side with the professional responders is the ideal way to do it. This is what we do.
