Definition of a Disaster 1. When the situation overwhelms the available resources 2. Example: Two people in a room or building uninjured, need to treat remaining injured people 3. Rescuers need to maintain safety through proper procedures and equipment B. Minimum Equipment 1. Helmet or hard hat a. To protect the head from falling debris and contact with sharp objects 2. Goggles or other form of eye protection a. To protect the eyes from dust, debris, and sharp objects 3. Leather work gloves a. To protect the hands from cuts and abrasions 4. Dust mask a. To protect the nose and respiratory tract against dirt and dust 5. Safety identification vest (bright orange with reflective tape) a. To identify those members who are trained and assigned a specific function 6. Flashlight a. To illuminate confined spaces and night time operations 7. Extra clothing and a hat a. To protect the body from cuts, abrasion, sunburn and evening cold 8. Sturdy and comfortable shoes or boots a. To protect the feet against cuts, abrasion, and sprained ankles b. High heels and sandals are unsafe Page 5 C. Operational Procedures 1. Buddy system a. Work in teams of at least two persons and stay together. 2. Safety officer a. If possible, each rescue team should have its own assigned safety officer. With limited personnel this is often not possible. Two person teams are more likely, making it even more important for both members to maintain a constant awareness of their surroundings. b. The safety officer should not actively engage in the rescue operation but watch out for hazardous conditions, unsafe actions, and overall rescue team safety. D. Communications 1. Radio or other forms of communications are vital to safely coordinate and control search and rescue operations. 2. Runners may be used where radios do not exist, or become inoperable. 3. When using a radio, if you haven't been answered, you haven't been heard. E. Entrapped Signal 1. Pre-arrange a signal for rescuers to use if they become entrapped. Yelling and whistles work well in open areas but sound vibrations have to travel farther in confined spaces. Tapping with a hard object onto a solid part of the structure can be heard further away than verbal sounds. 2. Similar to the international SOS signal: a continuous three taps - pause - three taps -pause is a suggested signal for entrapped rescuers or patients. F. Evacuation Signal 1. A loud identifiable and pre-arranged signal will be sounded when hazardous conditions require immediate evacuation of the structure. a. Whistle, megaphones, or bullhorns, etc. b. The following signals are internationally recognized by professional rescue teams: (I) Evacuate3-1 second blasts (II) Stop work/maintain silence1-3 second blast (III) Resume Operations1-3 second blast; 1-1second blast 2. Each team or structure should have its own distinct evacuation signal when multiple rescue operations are taking place in the same area. Page 6 G. Safety Hazards Around Disaster Sites 1. Secondary collapse of unstable structures a. Fractured or leaning buildings, walls, utility poles, freeway overpasses b. Shifting debris piles and building contents H. Overhead Hazards 1. Damaged attachment points not designed to hold this type of load can suspend large heavy pieces of the structure. 2. Unsecured building contents such as file cabinets, bathtubs, refrigerators, etc. 3. Low hanging wires i.e., electrical, phone, television cable, etc. a. Electrocution, tripping, and entanglement b. Might be found outside, under canopies, or inside rooms 4. Heavy lifting construction equipment a. Cranes and backhoes lifting heavy objects over rescuers 5. Unorganized rescue teams on floors and roofs above a. Places unnecessary weight and movement above rescuers I. Ground Level Hazards 1. Sharp objects like glass, nails, re-bar, and broken concrete 2. Slippery and uneven surfaces 3. Surface water a. Electrocution if contacting energized power lines b. Drowning 4. Contaminated atmospheres a. Areas of chemical storage, i.e. garage, basement areas b. Flammable, toxic, or oxygen deficient Page 7 J. Below-Grade Hazards 1. Contaminated atmospheres a. Basement or cellar storage areas b. Flammable, toxic, or oxygen deficient 2. Flooding a. Eliminates view of floor or walking surface b. Electrocution c. Drowning K. Basic Hazardous Materials Safety 1. Household hazardous materials a. Kitchen area (I) Ammonia, bleach, caustic oven and drain cleaners under sink b. Laundry area (I) Ammonia, bleach, spot remover in cabinets and near washing machines c. Garage area (I) Gasoline, paint thinners, pesticides, caustic paint removers, pressurized cans in cabinets, on shelves, and on floor 2. Hospitals and laboratories a. Flammable gases, flammable liquids, poisons, radioactive isotopes, and biological hazards 3. Schools, local retail, business offices a. Approved and unapproved items under sinks and in closets L. Basic Infectious Disease Safety 1. If patient does not have a disease prior to injury or death they will not be infectious because of the injury or death 2. Use the same type personal protective equipment already discussed a. Helmet (I) To protect the head from cuts and abrasions b. Goggles (I) Will stop body fluids from coming in contact with the eyes Page 8 c. Dust masks (I) Will stop body fluids from coming in contact with the face and respiratory tract d. Latex gloves (I) May have to put under leather work gloves to prevent body fluids coming in contact with the hands during work activities 3. Wash with soap or disinfectant as soon as possible if contact with body fluids 4. Remove or wash clothing with soap soon as possible if contact with body fluids 5. Immunization against Hepatitis B and tetanus should be kept current 6. Water contamination and broken sewage systems will cause most of illnesses following a structural collapse disaster unless proper purification and sanitation procedures are used. a. Schools will need to establish remote sanitation sites for human waste. The method and location for use and storage will need to be considered carefully. Page 9 LIGHT SEARCH AND RESCUE UNIT II SEARCH AND RESCUE METHODOLOGY Page 10 A. Majority of Rescues After a Disaster 1. Most rescues happen shortly after the event by uninjured people who were next to the injured people. 2. Civilian rescuers and not the usual emergency response organizations (fire, law enforcement, and medical) will perform the majority of rescues. 3. Emergency response organizations respond first to hazards which have major consequences, like large fires and haz-mat spills. Search and rescue for more severely trapped patients is attempted later. B. Most of the injuries are minor and can be prevented by securing building contents inside the structures. 1. Easy to identify building content hazards. 2. Easy and inexpensive to correct most building content hazards. C. Disaster Service Workers 1. You should be prepared to stay in your school until relieved. 2. Self Preparedness a. You and your family need to be prepared for a disaster. b. If the disaster occurs while you are at work you will be able to function more efficiently knowing your family is prepared and hazards were reduced. Page 11 D. Four Types of Structural Collapse Disaster Rescue Situations 1. Injured, Not Trapped a. Injury is usually caused by falling debris hitting the victim or the victim falling and hitting the ground. Also known as "surface victims". b. Removing the victim to a safe location and treatment of wounds is required for rescue. c. Usually accounts for 50% of victims. 2. Non-Structural Entrapment a. The building still looks like the original building. Also known as "light rescue". b. Building contents like file cabinets, book shelves, refrigerator, and small pieces of debris will trap victims. c. Locating the victim and lifting the building contents or small pieces of debris off them is usually accomplished with common hand tools. Removing the victim to a safe location and treatment of wounds is required for rescue. d. Usually accounts for 30% of victims. 3. Void Space Non-Structural Entrapment a. The building no longer looks like the original building. Partial or complete collapse has occurred. This is a hazardous and dangerous situation. b. Victims are still trapped by the building contents such as file cabinets, bookshelves, refrigerator, and small pieces of debris. But they are located inside void spaces created by the collapsed structure(s). c. Securing the structure, locating the victim, lifting the building contents or small pieces of debris off them, removing the victim to a safe location, and treatment of wounds is required for rescue. d. Rescuing a victim in this category usually takes about four (4) hours. e. Usually accounts for l5 of victims. Page 12 4. Entombed a. The building no longer looks like the original building. Partial or complete collapse has occurred. This is a very hazardous and dangerous situation. b. Victims are trapped by structural components like walls, floors, and roofs. c. Securing the structure, locating the victim, lifting, removing or breaching the structural components away from them, removing the victim to a safe location, and treatment of wounds is required for rescue. d. Rescuing entombed victims usually takes longer than four (4) hours. The average time is about eight (8) hours. e. Usually accounts for 5% of victims. Page 13 E. Four Training Levels For Each Type of Rescue Situation 1. Injured, Not Trapped a. Spontaneous Rescue Teams (I) (II) Co-workers, relatives, and civilians near the structural collapse. Preventing damage and injury from building contents with Non-Structural Hazard Mitigation programs and Basic First Aid. 2. Non-Structural Entrapment a. Disaster Assistance Response Teams (I) Business and Industry, City Employees, Schools, and organized community group teams. (II) In addition to the above training, basic tool knowledge used to release victims entrapped by building contents and small pieces of debris, utility control, basic fire fighting and basic urban search management and techniques. 3. Void Space Non-Structural Entrapment a. Emergency Service Providers (I) Fire departments, law enforcement, medical, military, volunteer search and rescue teams, and industrial response teams. (II) In addition to the above training, good tool knowledge and use to release victims entrapped by building contents and small pieces of debris inside voids of the collapsed structure. Basic structural collapse hazard awareness and mitigation techniques, and Incident Command System (ICS) training. 4. Entombed a. Urban Search and Rescue Teams Note: (I) Fire Departments, structural engineers, general contractors, and specialist rescue teams from the public, private and federal level. (II) In addition to the above training, any additional training useful in locating entrapped victims and lifting, removing or breaching structural components away from them. At least 80% of the injured and entrapped victims of past structural collapse disasters have been rescued within the first 24 hours following the incident. Page 14 F. The Five Stages of Rescue 1. STAGE I a. Scene organization & management (I) Establish the Incident Command Site (II) Establish a Medical Treatment Area (III) Assign staff according to the School Disaster Plan i.e. light search and rescue, damage assessment, communications, first aid, safety and security, sheltering and special needs (IV) Remaining staff and students become "worker resource pool" waiting for an assignment (V) Collect staff input and accounting information (VI) Assign Search and Rescue operations based on known victims and their location 2. STAGE II a. Rescue & remove surface victims (I) During the site survey (II) Exterior of structure only (III) On top of and under debris piles Page 15 3. STAGE III a. Search likely survival places (I) After completing Stage I utilizing “known victim” list (II) Type of structure (buildings that still look like buildings) (III) Time of day (people at work, kids in school, etc.) (IV) Info from staff, students, or visitors (V) Use search markings (/-enter and x -exit) b. Locating methods (I) Visual and vocal search (II) Hailing system c. Search building content voids (I) Identify type of void (II) Identify hazards (III) Search the building content void spaces (IV) Identify structural voids and report info to the Incident Manager (V) DO NOT ENTER buildings that don't look like the original building Page 16 4. STAGE IV a. Selected Debris Removal *** ERT members may assist at the perimeter*** of selected debris removal operations with direction and supervision from trained light search and rescue team members (PROCEDURES BELOW LINE EXCEED ERT MEMBER CAPABILITIES) (I) Remove all rescue personnel from structure (II) Correct all possible hazards (III) Develop a systematic plan for removing the selected portions of debris (IV) Selection of debris to be removed is based on highest probability of finding live victims (V) Keep number of rescue team members inside the structure to a minimum (VI) Remove debris from top and work towards the bottom (VII) Mark debris piles that have been removed to prevent future rescue teams from searching the rubble (VIII) Have a contingency plan if a live or deceased victim is found 5. STAGE V a. General Debris Removal *** ERT members may assist at the perimeter*** of general debris removal operations with direction and supervision from trained light search and rescue team members (PROCEDURES BELOW LINE EXCEED ERT MEMBER CAPABILITIES) Probability of finding live victims is highly unlikely (I) Structure and debris are systematically removed with heavy equipment without regard or preference to any particular location (II) Rubble removed from the structure must be inspected for bodies and body parts. (III) Any bodies or body parts found must be taken to a predetermined location. Page 17 Hailing System Entrapped Victim Locating Method 1. Place rescuers in calling and listening positions around the search area 2. Rescue team leader calls for silence and all work in the area to stop 3. Go "around the clock" each rescuer calls or taps some object 4. All rescuers listen and try to get a "FIX" on any sound they may hear 5. Any sound heard should be verified with at least one additional "FIX" from another angle Page 18 Page 19 Page 20 Page 21 LIGHT SEARCH AND RESCUE UNIT III SEARCH METHODS AND MARKINGS Page 22 A. The Search Function 1. Locating persons known to be in a general area 2. Ensure all persons are out of a specific location 3. Must be thorough and systematic to reduce duplication of effort 4. Use your school site map for search and rescue a. Contact the Incident Manager after completing the search of each area B. School Accounting Form 1. Identifies the students and staff currently present 2. Identifies the students and staff not present 3. Identifies the students and staff with injuries and their location C. Known Location of Victim 1. Go the most direct and safest route D. Unknown Location of Victim 1. Multiple rooms a. Enter: Go right and stay right (I) Stay in contact with the wall b. Exit: Go left and stay left (I) Stay in contact with the wall 2. Open Areas (recreation centers, churches, etc.) a. Line Search (I) Spread team members straight across the open area (II) Slowly walk through the area to the other side (III) Team members on the ends of the line search perimeter rooms usinggo right and stay right method E. Search Markings 1. Easy to read, easy to make, easy to understand 2. Use chalk, paint, crayons, tape 3. Start the marking symbol when you enter the room or structure, complete it when you exit Page 23 Page 24 Page 25 Page 26 Page 27 School Site Map Room 101 Room 102 Room 103 Room 104 Room 105 Room 106 Room 107 Room 108 Page 28 Page 29 LIGHT SEARCH AND RESCUE UNIT IV FIRST AID TRIAGE Page 30 S.T.A.R.T. Plan Simple Triage and Rapid Transport A. The Plan 1. Was developed for use in pre-hospital MCI's (Mass Casualty Incident) 2. Allows Emergency Medical Service personnel to survey a patient and quickly make an initial assessment for treatment and transportation needs. 3. Simple to learn and use, and utilizes the ABC's of patient assessment. 4. Does not require any special skills or specific patient diagnostics. 5. Allows for immediate stabilization of life threatening airway and bleeding problems. 6. Uses three criteria to categorize patients a. R - Respiration’s b. P - Perfusion c. M-Mental Status B. Step 1 1. Initial medical responder enters incident, identifies self, and directs all patients who can walk to gather and remain in a safe place. a. This will identify those patients that do not have respiratory, circulatory or mental/motor function problems b. Most of these patients will be tagged green (delayed) c. Do not tag at this time, these patients will be reassessed later d. This is the initial triage and patient status may change C. Step 2 1. Begin evaluating the non-ambulatory (unable to walk) patients where they are lying. 2. Assess RESPIRATIONS - normal, rapid, absent a. If absent, open airway to see if breathing begins b. If not breathing, tag black (dead) DO NOT PERFORM CPR c. If patient needs assistance to maintain open airway, or a respiratory rate greater than 30, tag red (attempt to use a bystander to hold airway open) d. If respiration’s are normal, go to next step Page 31 D. Step 3 1. Assess PERFUSION - pulse, bleeding a. Use the capillary refill test or check radial (wrist) pulse b. If capillary refill is greater than 2 seconds, or radial pulse is absent, tag red c. If capillary refill is less than 2 seconds, or radial pulse is present, go to next step d. Any life threatening bleeding should be controlled at this time, and if possible, raise patient's legs to treat for shock (attempt to use bystander to hold pressure for bleeding control) E. Step 4 1. Assess MENTAL STATUS - commands, movement a. Use simple commands/tasks to assess b. If patient can not follow simple commands, tag red c. If the patient can follow simple commands they will be tagged yellow or green d. This will depend on other conditions, where their injuries will determine the priority of yellow vs. green (i.e. multiple fracture would require a higher level of treatment than superficial lacerations) F. Conclusion 1. The S.T.A.R.T. Plan is a simple, step by step triage and treatment method to be used by all care providers at an MCI. 2. This method will allow for rapid identification of those patients who are at greatest risk for early death and the provision of basic life-saving stabilization techniques. Page 32 LIGHT SEARCH AND RESCUE UNIT V BASIC CONSTRUCTION AND UTILITY CONTROL Page 33 A. Basic Construction 1. More than a dozen different types of construction for buildings 2. The most common two a. Light frame construction b. Heavy wall construction B. Light Frame Construction 1. Light weight materials (usually wood) built with an internal framework which supports light weight floors and roofs giving the building a lot of flexibility 2. Hazards come from heavy objects attached to the outside of the structure a. Chimneys, brick veneer, heating and air conditioning units, etc. C. Heavy Wall Construction 1. Thick and heavy walls supporting light weight floors and roofs 2. Hazards a. Very rigid walls that can break and fall off. When the walls fail, nothing supports the floors and roofs b. Walls can fall their entire height away from the building c. Heavy objects attached to the building can fall off D. Stuck Doors 1. After buildings flex, doors can become stuck against the door frame 2. Make sure the door is unlocked before attempting to pry it open 3. Use whatever tools you have available a. A regular pry bar (crow bar) will work fine Page 34 Page 35 Page 36 Opening a Stuck Door Doors can become jammed after an earthquake. They are usually stuck because the door frame shifts and wedges against the door. First make sure the door is unlocked before attempting to force open any door. Force the top of a pry bar into the area which appears to be stuck. Push the pry bar against the door in the direction the door would normally open. Page 37 Utility Control Safety E. Natural Gas (Safety & Security Team will probably control) 1. Flammable, explosive, and oxygen deficient atmospheres 2. Shut off gas valve(s) next to structure after looking for fast moving dials that could indicate a leak inside the structure. F. Electricity (Safety & Security Team will probably control) 1. Electrocutions from direct contact with wires 2. Electrocution from energized metal objects in contact with wires 3. Fire or explosion ignition source 4. Shut off electricity by a. Shutting off circuit breaker panels and fuse boxes (I) Start at bottom and work up (II) Knife box switches (III) Start with small switches first b. Cutting drip loops (I) Only with proper training and equipment G. Water (Safety & Security Team will probably control) 1. Electrocution from water in contact with energized wires. 2. Weight of water pooled on floors or absorbed into the porous structural components could cause further collapse. 3. Drowning 4. Shut off the water valve(s) next to the structure and also the valve next to the street or alley, if possible.
