Inspection of Patient Compartment Supplies and Equipment Complete the inspection report. Correct any deficiencies. Replace missing items. Make your supervisor aware of any deficiencies that cannot be immediately corrected. Finally, clean the unit for infection control and appearance. Use only approved cleaning and disinfecting materials.
Think About It As I walk around the vehicle (engine-on and engine-off check), what information do I get from what I hear, see, and smell?
Receiving and Responding to a Call
Role of the Emergency Medical Dispatcher Ask questions of caller and assign priority to call Provide prearrival medical instructions to callers and information to crews Dispatch and coordinate EMS resources Coordinate with other public safety agencies continued on next slide
Role of the Emergency Medical Questions Dispatcher What is the exact location of the patient? What is your call-back number? What s the problem? How old is the patient? What s the patient s sex? Is the patient conscious? Is the patient breathing?
Operating the Ambulance Being a safe ambulance operator Be physically and mentally fit. Be able to perform under stress. Have a positive attitude about your ability as a driver but not be an overly confident risk taker. Be tolerant of other drivers. Never drive while under the influence of any substance.
Operating the Ambulance Being a safe ambulance operator Never drive while taking prescription medications that can impair your ability to operate a motor vehicle. Never drive with a restricted license. Always wear your glasses or contact lenses if required for driving. Evaluate your ability to drive based on personal stress, illness, and fatigue. continued on next slide
Operating the Ambulance Understanding the law An ambulance operator must have a valid driver s license and may be required to complete a training program. Privileges granted under the law to the operators of ambulances apply when the vehicle is responding to an emergency. Not applicable if not on call continued on next slide
Operating the Ambulance Understanding the law Even though certain privileges are granted during an emergency, the exemptions granted do not provide immunity to the driver. Privileges granted during emergency situations apply only if the operator uses warning devices in the manner prescribed by law. continued on next slide
Operating the Ambulance Understanding the law Most statutes allow: Parking wherever necessary as long as life and property are not endangered Proceeding past stop signs/signals Exceeding the posted speed limit as long as life and property are not endangered Passing other vehicles in no-passing zones after properly signaling and taking precautions continued on next slide
Operating the Ambulance Understanding the law Most statutes allow: Disregard for regulations that govern direction of travel and turning in specific directions with proper caution and signals Laws interpreted by the court based on: Using due regard for safety of others Whether to the best of your knowledge, the situation was a true emergency continued on next slide
Operating the Ambulance Using the warning devices The siren Never use it indiscriminately. The horn Visual warning devices Day or night Vehicle should be easily seen from 360 degrees in emergency response mode. continued on next slide
Operating the Ambulance Speed and safety Excessive speed increases the probability of a collision. Speed increases stopping distance, reducing the chance of avoiding a hazardous situation. continued on next slide
Operating the Ambulance Escorted or multiple-vehicle responses Inexperienced ambulance operator often follows the escort vehicle too closely and is unable to stop when the lead vehicle makes an emergency stop. Recommendation of no escorts unless absolutely necessary Greater care must be used. continued on next slide
Operating the Ambulance Factors that affect response Day of the week Time of day Weather Road maintenance and construction Railroads Bridges and tunnels Schools and school buses continued on next slide
Operating the Ambulance Navigating to the scene Global positioning satellite (GPS) navigation often installed No substitute for an intimate knowledge of the response area. May become a distraction Obtain detailed maps of your service area. continued on next slide
Operating the Ambulance Response safety summary Minimize lights-and-siren hot responses. Driving with lights and siren involves high risk. Wear your seat belts. Know where you are going before you respond. Use the GPS and check the maps. Be familiar with your response area. continued on next slide
Operating the Ambulance Response safety summary Come to a complete stop at intersections. Don t be a distracted driver. Have the crew leader operate the radio, siren, GPS, computer, and other devices. Pay complete attention to safe driving. continued on next slide
Operating the Ambulance Safety at highway incidents Keep unnecessary units and people off the highway Avoid crossovers unless a turn can be completed without obstructing traffic If yours is the first unit on scene Park apparatus "upstream" from incident continued on next slide
Operating the Ambulance Safety at highway incidents Wear Your PPE Place cones/flares and reduce Emergency lighting Unit placement is important! Backing up Avoid backing up, if possible, especially during emergencies.
Transferring the Patient to the Ambulance
Transferring the Patient to the Ambulance 1. Select proper patient-carrying device 2. Package patient for transfer 3. Move patient to ambulance 4. Load patient into ambulance
Four Steps of Transferring This patient is packaged for cold, wet conditions.
Transferring the Patient to the Ambulance Packaging the patient Readying patient to be moved and combining patient and patient-carrying device as unit ready for transfer Sick or injured patient must be packaged so that condition is not aggravated. continued on next slide
Transferring the Patient to the Ambulance Packaging the patient Before placing patient on carrying device Complete necessary care for wounds, other injuries. Stabilize impaled objects. Check dressings and splints. Cover patient and secure to patientcarrying device. continued on next slide
Transferring the Patient to the Ambulance Protecting the patient Must be secured to patient-carrying device Minimum of three straps to secure Chest level Waist level Lower extremities Use shoulder harness if available. continued on next slide
Transferring the Patient to the Protecting the EMT Ambulance EMT at greater risk in patient compartment Make sure all equipment is secured. Remain seated. Wear seat belt and harness if possible. Avoid unnecessary movement during response and transport.
Transporting the Patient to the Hospital
Preparing the Patient for Transport Continue assessment. Secure stretcher in place in ambulance. Position and secure patient. Adjust security straps. Prepare for respiratory and cardiac complications. continued on next slide
Preparing the Patient for Transport Loosen constricting clothing. Load relative or friend who must accompany patient. Load personal effects. Talk to your patient. Avoid letting patients sit on bench or airway seat.
Caring for the Patient en Route Notify the hospital. Continue to provide emergency care as required. Use safe practices during transport. Compile additional patient information. Continue assessment and monitor vital signs. Notify the receiving facility.
Pediatric Note The entire scene may create a terrifying experience for a child. A toy such as a teddy bear can do much to calm a frightened child. The presence of a female EMT or police officer may be helpful. Small children do not, as a rule, carry identification.
Transferring the Patient to the Emergency Department Staff
Transferring the Patient to the Emergency Department Staff If routine admission situation or when an illness or injury is not life threatening injury, check first to see what is to be done with patient. Assist emergency department staff as required, and provide a verbal report. continued on next slide
Transferring the Patient to the Emergency Department Staff As soon as you are free from patientcare activities, prepare the prehospital care report. Transfer the patient's personal effects. Obtain your release from the hospital.
Terminating the Call
At the Hospital Quickly clean the patient compartment while taking appropriate Standard Precautions. Prepare respiratory equipment for service. Replace expendable items. Exchange equipment according to your local policy. Make up the ambulance cot.
Terminating the Call: At the Hospital 1. A low-level disinfectant approved by the U.S. Environmental Protection Agency (for example, a commercial product such as Lysol) will clean and kill germs on ambulance floors and walls.
En Route to Quarters Radio the EMD. Air the ambulance if necessary. Refuel the ambulance.
Terminating the Call: En Route to Quarters 6. Replace expendable items as required.
In Quarters Place badly contaminated linens in a biohazard container and noncontaminated linens in a regular hamper. As necessary, clean any equipment that touched the patient. Clean and disinfect used nondisposable respiratory-assist and inhalation therapy equipment. continued on next slide
In Quarters Clean and sanitize the patient compartment. Prepare yourself for service. Replace expendable items. Replace or refill oxygen cylinders. Replace patient-care equipment. continued on next slide
In Quarters Carry out postoperation vehicle maintenance procedures as required. Clean the vehicle. Complete your paperwork.
Air Rescue
When to Call for Air Rescue Operational reasons To speed transport to distant trauma center When extrication of high-priority patient is prolonged and air rescue can speed transport When patient must be rescued from remote location
When to Call for Air Rescue Patients are sometimes transported by air rescue helicopter.
When to Call for Air Rescue Clinical reasons Patient in shock Glasgow Coma Scale total less than 10 Head injury with altered mental status Chest trauma and respiratory distress Penetrating injuries to body cavity continued on next slide
When to Call for Air Rescue Clinical reasons Amputation proximal to hand or foot Extensive burns Serious mechanism of injury Patient is post cardiac arrest with a pulse.
How to Call for Air Rescue Name and call-back number Agency name Nature of situation Exact location Crossroads, major landmarks Exact location and description of landing zone If possible, GPS coordinates
How to Set up a Landing Zone Describe the landing zone to the air rescue service. Terrain Major landmarks Estimated distance to nearest town Other pertinent information Such as wires, ditches, or wind
Landing Zone Helicopter landing zone.
Landing Zone (A) The area around the tail rotor is extremely dangerous. A spinning rotor cannot be seen.
How to Approach a Helicopter Do not approach unless escorted by flight personnel. Allow the crew to direct loading of the patient. Stay clear of tail rotor at all times. Keep all traffic and vehicles at least 100 feet from the helicopter. Do not smoke near the aircraft. Be aware of danger areas.
Chapter Review
Chapter Review Inspect the vehicle to assure that it is complete and that critical items can be easily located. A "hot" response means using lights and siren. Hot responses involve high risk. A "cold" response means no lights or sirens. Cold responses decrease risk. continued on next slide
Chapter Review The laws in most states allow the driver of an emergency vehicle running "hot" to break some of the vehicle and traffic laws. However, it must be done with due regard for the safety of others. Pay attention to driving! Do not text, make phone calls, drink beverages, or be in any way distracted while driving. continued on next slide
Chapter Review Secure all gear. It can become a projectile in a crash! Do not let your patient become a projectile. Use the stretcher shoulder straps. continued on next slide
Chapter Review Wear your seat belt in front and back (whenever possible). Know the medical and operational reasons for helicopter transport and know how to set up a safe landing zone.
Remember Ambulances must be properly stocked and prepared. Pre-call inspections assure readiness and appropriate equipment. Emergency Medical Dispatchers enhance patient care by providing prearrival instructions and by obtaining information for responders. continued on next slide
Remember Each state has statutes regulating operation of emergency vehicles. EMTs must be familiar with local rules and regulations. EMTs should use good judgment and due regard for safety of others when operating an ambulance. continued on next slide
Remember The four steps involved in transferring the patient to the ambulance are selecting proper patient-carrying device, packaging patient for transfer, moving patient to ambulance, and loading patient into ambulance. continued on next slide
Remember Patients should be safely secured prior to the ambulance's moving. Assessment and care must continue during transport. The primary concern of transfer of care is continuation of patient care. Failure to do so properly can be considered abandonment. continued on next slide
Remember Cleaning the ambulance, replacing used supplies and equipment, and readying the ambulance stretcher are important elements the EMT must complete while terminating a call. However, EMTs should be prepared for unusual circumstances. continued on next slide
Remember Indications for utilizing air rescue may include both operational and medical reasons. EMTs should be familiar with local protocols for accessing and utilizing air rescue transport.
Questions to Consider Does the patient have a true emergency adversely affected by time? How can I park to best protect the scene and personnel? Does my personal protective equipment "match" what is being worn by others?
Critical Thinking What equipment should you include in a kit that you carry to the scene? How should the equipment be positioned so that you can reach urgently needed items quickly? What special items, if any, should be in the kit to meet local needs?

Secondary Triage and Treatment Secondary triage is performed at a patient collection point or triage area. Patients are separated into treatment groups based on their priority level. Each treatment area should have its own treatment supervisor. It may be necessary to recategorize a patient whose condition has deteriorated or improved.
Transportation and Staging Logistics Once assessed, triaged, and treated, patients are transported according to priority. Ambulances in staging area in designated area to await direction and patients continued on next slide
Transportation and Staging Staging supervisor Logistics Transportation supervisor Overwhelming a hospital's surge capacity could bring about poor outcomes.
Communicating with Hospitals Receiving facilities contacted early to determine capabilities and update on expected patient counts Transportation officer, not individual EMTs, should communicate. Generally too many patients to allow a good radio report Only basic information given
Psychological Aspects of MCIs Caring, honest demeanor can reassure patient. Do not attempt to psychoanalyze a person's distress. "Psychological first aid" may be necessary on the scene of MCI.
Think About It If you are the first rescue vehicle to reach the scene of an MCI, what should you do?
Chapter Review
Chapter Review Maintain a high index of suspicion and awareness. Many hazmat incidents start out as routine EMS calls. The biggest problem in most hazmat incidents in identifying the offending substance. Look for the shopping placard and the SDS. Use the Emergency Response Guide to help determine your initial actions. continued on next slide
Chapter Review Remember the hot zone warm zone cold zone. Once you realize it's a hazmat incident, get to the cold zone and call for help. Keep responders in rehab until they are rested, hydrated, and vitals return to normal. continued on next slide
Chapter Review Patients who have been "decontaminated" almost always still have some contamination. Patients being transported must be cared for by competent EMS responders with Operations-level training and equipment. continued on next slide
Chapter Review Use your MCI plan and procedure at small incidents, as this will make managing larger ones will be easier. NIMS and Incident Management are the national standard for incident management. continued on next slide
Chapter Review Learn and practice START triage essentials. Be alert for signs of stress after incidents, and seek help as necessary.
Remember A hazardous materials response requires specialized training and resources. Common responsibilities of initial responders must be identification of the incident, scene control, and activation of appropriate resources. continued on next slide
Remember Scene safety is highest priority; when possible, use scene clues, product information, and specific resources to identify hazardous materials. Decontamination prevents the spread of a hazardous material. EMTs are commonly involved in various levels of this process. continued on next slide
Remember Multiple-casualty incident overwhelms resources of responding units. When this occurs, organization is the most important priority. NIMS and its incident command system provide organization resources and structure to improve management of large-scale incidents. continued on next slide
Remember Triage allows EMTs to prioritize care and transport of patients when resources are limited.
Questions to Consider What is the hazardous substance? What risk does it pose? If a patient has some contamination, can we safely start decontamination? Should I start using triage tags?
Critical Thinking Your call is to a motor-vehicle collision with an unknown number of injuries. As your unit approaches the scene, you see that three cars and downed wires are involved. You get a whiff of gasoline as you pass by. continued on next slide
Critical Thinking The drivers are visible in each vehicle one appears to be conscious and the other two are bent forward or slumped back. There are passengers visible in two vehicles, one or more of whom may need extrication. How should you proceed?
Emergency Care THIRTEENTH EDITION CHAPTER 38 Highway Safety and Vehicle Extrication
Multimedia Directory Slide 50 Rapid Extrication Video
Topics Highway Emergency Operations Vehicle Extrication
Highway Emergency Operations
Highway Emergency Operations Oncoming traffic at highway incidents is one of the greatest hazards emergency responders face today. Responding agencies and personnel need to be cognizant of their responsibilities in these types of hazardous environment. continued on next slide
Highway Emergency Operations EMS response should be limited to only the manpower and vehicles needed to accomplish the mission. The first-arriving unit should institute "blocking" to protect the work area. Preferably fire apparatus If it is necessary to block lanes of traffic, clear them quickly as possible so flow of traffic can return to normal.
Highway Emergency Operations A vehicle collision where extrication of the patient is required is the most common type of rescue across the United States. Edward T. Dickinson, MD
Initial Response Limited access highways Only primary or first-due units should proceed directly to scene. On-scene units Park single file in same direction to minimize on-scene congestion. continued on next slide
Initial Response First-arriving units should: Establish Command and confirm exact location of incident with dispatch center. Use apparatus to institute "upstream blocking" to protect work area. Rescue trucks arriving to perform extrication should be positioned downstream of initial blocking vehicle.
Position Blocking Apparatus Create one and a half to two lanes of blockage. Position apparatus at angle with front wheels rotated away from incident.
Position Blocking Apparatus Positioning the other apparatus Leave space immediately next to crash for vehicle extrication units. Position ambulances, command vehicles, and other units downstream from crash. Allows safer patient loading and rapid departure from scene
Exiting the Vehicle Safety Responders should always exit into the safe zone, if possible, after checking to be sure traffic has stopped. Be alert for oncoming traffic.
Be Seen and Warn Oncoming Traffic Place flares or traffic cones to slow traffic and channel away from incident lane. Night operation Shut off vehicle's headlights and white response lights
Night Operations Shut off vehicle's headlights and white response lights. Best combination of lights to provide maximum visibility Red/amber warning lights on Headlights off Fog lights off Traffic directional boards operating
Think About It Is it safe to enter the highway scene? Which units are necessary?
Vehicle Extrication
Vehicle Extrication Phases Preparing for rescue Sizing up the situation Recognizing and managing hazards Stabilizing vehicle prior to entering Gaining access to patient continued on next slide
Vehicle Extrication Phases Providing primary patient assessment and rapid trauma assessment Disentangling patient Immobilizing and extricating patient from the vehicle Providing assessment, care, and transport to most appropriate hospital Terminating the rescue
Preparing for Rescue Combination of training, practice, and the right protective gear and tools Availability of training will depend on the kinds of rescues most likely to be required in your area.
Sizing Up the Situation Conduct a good size-up to evaluate hazards and address need for additional resources. How many patients are involved, their priority, and MOI? Are additional ambulances needed? What is extent of patient's entrapment?
Think About It What does scene size-up tell me about the need for extrication?
Recognizing and Managing Hazards Protective gear for EMS responders At a crash any personnel working in the "inner circle" should wear full protective gear to avoid being injured. If your service does not provide protective gear, then get your own. Use your protective gear! continued on next slide
Recognizing and Managing Hazards Protective gear for EMS responders Working in traffic Wear helmet. Wear safety vests to enhance visibility. Wear ANSI safety vests when working in highway operations per federal highway standards. continued on next slide
Recognizing and Managing Hazards Protective gear for EMS responders During extrication operations Increased risk of exposure to flame, glass, fluids, and sharp objectives Best practice to wear EMS or firefighter turnout clothing including helmet and eye protection Matching the level others are wearing Look at other workers in the industry. continued on next slide
Recognizing and Managing Hazards Protective gear for EMS responders Helmets Eye protection Hand protection Body protection
Protective Gear for EMS Responders Complex access involves the use of tools and equipment to reach and extricate the patient. Edward T. Dickinson, MD
Safeguarding Your Patient To protect your patient, you should have: Aluminized rescue blanket Lightweight vinyl-coated paper tarpaulin Wool blanket Short and long spine boards continued on next slide
Safeguarding Your Patient To protect your patient, you should have: Hard hats, safety goggles, industrial hearing protectors, disposable dust masks, and thermal masks Emotional support for the patient
Managing Traffic Use ambulance and its warning lights as first form of traffic control Position other warning devices as soon as possible Using flares for traffic control Look for and avoid spilled fuel, dry vegetation, other combustibles, especially at a road edge. Do not throw out of moving vehicles.
Supplemental Restraint Systems: Air Bags Air bags designed to inflate on impact, dissipate kinetic energy, minimize trauma to body Creates "smoke" in vehicle Cornstarch and talcum powder (and sometimes sodium hydroxide) Watch for an air bag that remains undeployed after a crash.
Energy-Absorbing Bumpers If the bumpers were involved in the collision, you may notice that the bumper's shock absorber system is compressed, or "loaded." Never stand in front of a loaded bumper. Diagonal or perpendicular instead Chain the shock absorber to prevent an uncontrolled release.
Spectators May interfere with rescue and emergency care efforts in addition to traffic. If policies permit, ask responsiblelooking bystanders to keep spectators away. Give barricade tape. Do not put in unsafe positions. You may be held liable in adverse event.
Electrical Hazards High voltage lines common Assume entire area around exposed wire dangerous. Conductors may have touched and energized. Ordinary protective clothing gives no protection against electrocution. continued on next slide
Electrical Hazards Broken utility pole with wires down Very dangerous Set up a large safety zone and discourage occupants of collision from leaving the wreckage. Determine the number of the nearest pole you can safely approach, and ask your dispatcher to advise the power company of the pole number and its location. continued on next slide
Electrical Hazards Broken utility pole with wires down Do not attempt to move downed wires. Stand in a safe place until power company disconnects the power or cuts the wire. Broken utility pole with wires intact Park the ambulance outside the danger zone. Notify your dispatcher of the situation. continued on next slide
Electrical Hazards Broken utility pole with wires intact Stay outside the danger zone until power company representatives can deenergize the conductors and stabilize the pole. Keep spectators and other emergency service personnel out of the danger zone. continued on next slide
Electrical Hazards Damaged pad-mounted transformer Request an immediate power company response. Do not touch either the transformer case or a vehicle touching it. Warn other emergency personnel. Stand in a safe place until the power company de-energizes it. Keep spectators out of the danger zone.
Vehicle Fires Small fires 15- or 20-pound class A:B:C dry chemical fire extinguisher extinguishes almost anything burning. Fire in the engine compartment Do not attempt extinguishment unless hood fully open.
Vehicle Fires Extinguishing a fire in the engine compartment when the hood is fully open.
Vehicle Fires Fire in the passenger compartment or trunk Apply extinguisher sparingly until occupants can be freed. If in trunk, apply same principles as engine compartment fire. Fire under the vehicle Sweep from under the passenger compartment continued on next slide
Vehicle Fires Truck fires A:B:C extinguisher Burning truck tires are especially dangerous. Never stand directly in front of one. Flames can spread to cargo or the tires can explode.
Disabling a Vehicle's Electrical System Remember that many cars have electrically powered door locks, window operators, and seat adjustment mechanisms. Disconnect the negative cable from the battery.
Stabilizing a Vehicle Vehicle on its wheels Turn off engine. Step-chock three sides.
Stabilizing a Vehicle Stabilizing a car on its wheels with cribbing while patient contact is initiated.
Stabilizing a Vehicle Vehicle on its side Stabilize with ropes, cribbing, or stabilizer bars. Vehicle on its roof Utilize 4 4 wood blocks to build crib box.
Stabilizing a Vehicle A vehicle on its side stabilized with struts. For maximum stability, it may be best to place cribbing on one side, struts on the other.
Gaining Access Simple access Check if door or window can be opened. "Try before you pry." Complex access Utilize tools and equipment. Break glass in side or rear window as far from passengers as possible.
Disentanglement: A Three-Part Action Plan Steps one and two: gain access by disposing of doors and the roof Makes vehicle interior accessible Creates large exit Provides fresh air and helps cool heated patient Quick access to critical patient can improve survivability and perhaps decrease morbidity continued on next slide
Disentanglement: A Three-Part Action Plan Step three: disentangle occupants by displacing the front end Easily accomplished with heavy duty jacks and hacksaws Do not cut steering column or airbag wiring; may cause unexpected firing.

Chapter Review
Chapter Review Remember, highway operations are high risk. Take these precautions: Wear high-visibility garments. Position the ambulance for blocking until fire apparatus arrives. Then positions ambulances "downstream" in the safe zone. continued on next slide
Chapter Review Remember, highway operations are high risk. Take these precautions: Reduce lighting that may blind passing drivers. Avoid crossing traffic lanes with patients. continued on next slide
Chapter Review Scene size-up is key. How many patients are there? What is the triage status? Are additional resources needed? Protect yourself. Look out for: Traffic Undeployed airbags Loaded bumpers Sharp metal continued on next slide
Chapter Review Match the level of PPE being worn by other public safety responders. Ensure scene safety: If wires are down, keep spectators back. Make sure the vehicle is stable. First try simple means to gain access. Protect your patient during the extrication process.
Remember Highway response is a significant safety hazard for EMTs. Specific safety planning and procedures must be utilized to keep responders safe. Responding units should evaluate need for further units, institute "blocking" to protect work area, and always exit apparatus into safe zone. continued on next slide
Remember Use protective equipment and warning devices. Vehicle extrication often requires specialized training and resources. Know local resources and procedure for activating those resources. continued on next slide
Remember Determine extrication resources needed and patient extrication priority through thorough scene size-up. Extrication can pose a variety of threats. Evaluate the scene carefully and employ safety procedures. continued on next slide
Remember Gaining access to patients frequently requires mechanical and technological assistance. Always start simply and escalate only when simple measures fail.
Questions to Consider What is the best access for my unit? Where should I park the apparatus? Does the vehicle need to be stabilized?
Critical Thinking The highway crash you are dispatched to is a seven-car pile-up. Your unit is first on the scene. What steps are required that are different from those for a crash involving one car striking a tree?

Defining Terrorism "The unlawful use of force or violence against persons or property to intimidate or coerce a government, the civilian population or any segments thereof, in furtherance of political or social objectives" The U.S. Department of Justice, Federal Bureau of Investigation
Domestic Terrorism Groups or individuals whose terrorist activities are directed at a government or population, without foreign direction Environmental terrorists Antigovernment militias Racial-hate groups Groups with extreme political, religious, or other philosophies or beliefs
International Terrorism Groups or individuals whose terrorist activities are foreign based and/or directed by countries or groups outside the targeted country or whose activities cross national borders. Growing trend toward loosely organized, international networks of terrorists
Types of Terrorism Incidents Incidents of terrorism may involve CBRNE agents. Chemical Biological Radiological Nuclear Explosive Also called weapons of mass destruction (WMD)
Terrorism and EMS
Terrorism and EMS The Twin Towers of the World Trade Center in New York City were destroyed and thousands were killed on September 11, 2001, when terrorists flew hijacked jetliners into the famous skyscrapers. AP Images/Shawn Baldwin
Emergency Medical Responders as Targets Emergency Medical Responders are often principal targets of terrorist attacks. Safety of EMS provider is most important consideration when responding to potential terrorist incident.

Critical Information about Biological Incidents Exposure versus contamination Exposure occurs when a substance is taken into the body through one of the routes of exposure. Permeation Spreading or movement of a substance through a surface or, on a molecular level, through intact materials. Remove clothing but preserve dignity.
Types of Harm from Biological Incidents Chemical harm Scene of clandestine laboratory Etiological harm Agents classified as poisons Mechanical harm Explosives used to disperse agents Psychological harm Even the thought can cause distress.
Self-Protection Measures at a Biological Incident PPE and respiratory protection Get as much information as possible. Prioritize protective measures. Self-protection Buddy system Availability of Rapid Intervention Teams Civilian protection
Responses to a Radiological/Nuclear Incident Small nuclear devices ("suitcase bombs") stockpiled in foreign nations Radiologic dispersion more practical and difficult to detect as radiation symptoms are delayed for hours or days Sickness treatable if detected early
Types of Harm from Radiological/Nuclear Incidents Thermal harm Nuclear explosion Radiological harm Radiological materials Ongoing hazard Chemical harm Radiological substances also chemical hazards continued on next slide
Types of Harm from Radiological/Nuclear Incidents Mechanical harm Explosion Psychological harm Immediate or delayed reaction
Self-Protection Measures at a Radiological/Nuclear Incident Time, distance, shielding Radiologic detecting equipment helps determine effectiveness of measures. Assume dissemination of radiological, biological, or chemical materials. Follow decontamination procedures.
Responses to an Explosive Incident Wide variety of devices from small pipe bombs to large vehicle bombs May involve attacks on a fixed target or group of people May be designed to disperse biological, chemical, or radiological materials
Types of Harm from Thermal harm Explosive Incidents Heat of detonation Asphyxiation harm Possibility of extremely dusty conditions Chemical harm Result of explosive reaction from chemicals present at detonation site continued on next slide
Types of Harm from Explosive Incidents Mechanical harm Typically seen at bombing incidents Psychological harm Stunned response can last seconds or minutes Delayed response in the form of posttraumatic stress
Self-Protection Measures at an Explosive Incident Responder needs both preblast and postblast protection. Preblast Operations occurring after written or verbal warning received but before explosion takes place Postblast Operations occurring after at least one detonation
Dissemination and Weaponization
Respiratory Route Most effective, most common means Vast and delicate surface area Various levels, sizes of passageways into lungs
Other Routes Ingestion route Dermal route Human-to-human contact
Weaponization Most effective when targeted through inhalation route Particles in 3 to 5 microns in diameter Such airborne dissemination can be created by applying energy to material. Heat, explosives, and sprayers can aerosolize materials.
Characteristics of CBRNE Agents
Chemical Agents Chemical agent considerations Physical Can be gaseous, liquid, or solid Vapor pressures and densities can vary across the spectrum. Volatility Low boiling point and high vapor pressure will evaporate more readily. Allows agent to have greater airborne release potential continued on next slide
Chemical Agents Chemical agent considerations Chemical Sufficiently stable to survive dissemination and transport to site of action Toxological Not all individuals of a species react in the same way. Route of entry can also influence.
Chemical Agents Some emergency and rescue services carry detectors to help identify the presence of various CBRNE agents. Examples include this chemical agent monitor.

Strategy and Tactics
Strategy and Tactics The DOT Emergency Response Guidebook provides information for the common terrorist weapons. Strategies Broad general plans designed to achieve desired outcomes Tactics Specific operational actions responders take to accomplish assigned tasks
Isolation Initial considerations Controlling scene, isolating hazards, and attempting to conduct controlled evacuation is resource-intensive and requires law enforcement personnel. Establishing perimeter control Law enforcement must establish and control perimeter throughout incident. continued on next slide
Isolation Perimeter control factors Amount and type of resources on hand Capability of available resources Ability of resources to self-protect Size, configuration of incident
Notification Generally required by established directives, procedures, and statutes Request for additional specialized agencies carried out by communications center based upon early reports of EMTs on scene
Identification Observe indicators of particular agent or presence of chemical containers or lab materials Consult current edition of Emergency Response Guidebook
Protection People, vehicles, equipment/supplies Make an initial scene size-up to determine security threats. Request protection (read security) via radio as soon as practical. Establish vehicle staging and triage/treatment areas in protected locations. continued on next slide
Protection Advise EMS Command about protection/security concerns. Immediately report suspicious people or activities.
Decontamination Gross decontamination by EMS personnel Removing surface contamination via mechanical means and initial rinsing Amount of surface contamination significantly reduced
