- 1. Overview of HazMat and Mass Casualty Incidents
- 2. Overview of HazMat • Hazardous Materials • Any substance capable of creating harm to: • People • Property • Environment • Types • Explosives –Gases – Flammable/combustible liquid Flammable solids –Oxidizing substances Poisonous/Infectious substances –Radioactive substances Corrosive substances – Miscellaneous hazmat
- 3. General Info • Common problem • Actual extent unknown • Safety is primary concern • Providers • EMT-B and crew • Pt • Public
- 4. Approaching the Scene • Identification • Occupancy • Containers –size/shape • Placards • Shipping papers • “Bill of lading”- Road transport • “Way Bills” – Transport by rail • Usually in cab of truck • Chemical name, transport name, ID numbers • Senses • Material Safety Data Sheets (MSDS) • -1st . Aid, Decontamination, routes of exposure, S/S • protective equipment, past med Hx. Complications • Pts at the scene • Multiple pt with same S/S suggests exposure • i.e Nausea, vomiting, SOB, unresponsiveness
- 5. Approaching the Scene • General procedures • Park upwind and uphill • Keep unnecessary people away • Isolate area • Keep people out • Do not enter without proper equipment and SCBA • Local Resources • Local HazMat response teams • CHEMTREC = 1-800-424-9300 • Hazardous Materials, The Emergency Response Handbook • Published by US DOT
- 7. HazMat Zones • Hot Zone • Where the hazardous material is spilled • Only trained individuals/appropriate clothing • Warm Zone • Transmission zone • Where decontamination occurs • Control point between Cold and Hot zones • Suitable training and clothing • Cold Zone • “Clean zone” • Where pt are brought for EMS assessment prior to transport • Staging supplies and command
- 9. HazMat Decontamination • Mechanical Removal • Clothing Removal • Rinsing • Dilution • Absorption • Chemical Washes • Disposal/Isolation
- 10. MCI: Classification • Multiple/Mass Casualty Incident • A situation in which the needs is more than the initial responding personnel and equipment can meet • Open Incident • Easy access to victims from different locations • May be spread over a large area • Closed Incident • Physical/geographical barriers that prevent speedy access to victims • Active • Forces that contributed to the disaster are still active • On going risk to rescuers, public, victims • Contained • Forces responsible for the disaster are exhausted
- 11. Incident Management Systems • What are they? • Organized system of roles, responsibilities, and standing operating procedures to manage emergency operations. • What do they do? • Provides orderly means for communication and information for decision making • Makes interactions with other agencies easier
- 12. Incident Management Systems Structure • Command • Mobile site near the MCI • Overall command of the incident is coordinated • Extrication • Coordination of personnel/resources during extrication • Triage • Initial triage occurs at pt side • Pt relocated to “secondary triage” • Treatment • Organized sector where major field treatments are administered • Priority treatment may start at the side of pt before transport • Transportation • Responsible for overall transport of supplies, equipment, personnel, pt, other resources • Staging • Area where ambulances stage to receive pts and assignment of receiving hospital • Supply • Area where supplies are stockpiled • Rehabilitation • Area where care is given to rescuers • Physical and psychological support are offered
- 13. Incident Management Systems Documentation • A major event log • # of pts • Conditions and triage categories • Vehicles at scene • Personnel at scene • Hospital availability • # of individuals transported • Hospital disposition • Mode of transport
- 15. Initial Roles of Responders • Rescuers will be assigned specific duties within one of the sectors • Upon arrival • Report to sector officer • Once assigned a specific task • Complete it • Report back to sector officer
- 16. Triage • Heroic resuscitative efforts NOT appropriate • Too much time • Requires equipment used for salvageable patients • Staffing intensive • Concentrate on salvageable patients
- 17. MCI Procedures • Est. type of incident • Determine specific location and ID best access routes • 1 EMT approaches scene and determines: • Estimates # of pt • Estimates injury types • If incident is open/closed and active/contained • 2nd EMT stays with ambulance and determines: • Possible staging areas • Traffic routes into area • Both EMTs should ascertain • Approx # of pts • Specific location of incident • Whether incident is open/closed and active/contained • Need for special resources • # of additional ambulances needed • Potential dangers to public safety and personnel • IMMEDIATELY relay this info to communications center
- 18. MCI Procedures Cont’d • Most knowledgeable EMT on scene initially assumes Triage Officer • Request additional help • Perform initial assessment of all pts • START Triage • Assign available personnel/equipment to critical pts • Secondary Triage • In depth assessment of pt • In treatment area OR en route to ER • Pt transport is based on: • Prioritization • Destination facilities • Transport resources • Triage officer remains in scent to: • Assign/coordinate: Personnel, equipment, vehicles
- 19. Triage Stages • 1st Stage • No treatment is rendered • Victims are tagged with tape/cards • Category of injury • Likelihood of survival • 2nd Stage • Begins after removal of pt and transport to safer area • More thorough assessment • Recategorized by priority • Collection point of all pts • Ensure appropriate treatment and transport • ALS procedures • 3rd Stage • Certain specific cases • Creation of field hospital on site • ALS procedures
- 20. START Triage • “Simple Triage and Rapid Treatment” • Technique for quick primary triage • Assesses: • Ability to walk • Respirations • Pulse • Mental Status
- 21. START Triage: Minimal Treatment • Only THREE patient interventions are: • Open the airway Open the airway • Stop gross bleeding • Safe patient positioning • Shock position • Recovery position
- 22. START Triage Procedure • Walking • Walking pt= “Walking Wounded” = Green • Remain in location OR • Walk to treatment area • Breathing (open airway) • If absent = Dead/Dying = Black • Rate less than 10 or greater than 30 = Critical = Red • Pulse/Perfusion • If absent= Dead/Dying = Black • No radial/Present Carotid= Critical = Red • Radial and Carotid present= Assess mental status • Mental Status • Ask pt to perform two simple tasks • Motor = Lifting arm • Mental= Stating name, day, year • If they can do both = Delayed = Yellow • If they fail one = Critical = Red
- 25. Pt Categorization Minor • Green- Hold Priority • Definition • Pt with minor injuries • Injuries of an ambulatory nature • Pt Diagnosis • Minor fractures • Minor wounds • Burns less than 10% BSA • No airway problems • Psychological problems
- 26. Pt Categorization Delayed • Yellow- Delayed Priority • Definition • Pt requiring care but whose condition will not worsen with prompt (vs. immediate) transport • Pt Diagnosis • Burns • Multiple/major fractures • Spinal cord injuries • Uncomplicated head injuries
- 27. Pt Categorization Immediate • Red- Immediate Priority • Definition • Critical pt wit life threatening conditions who have a chance to survive with early stabilization and transport • Require hospital care within 1 hour • Pt Diagnosis • Airway/Respiratory difficulties • Sever burns • Cardiac problems • Uncontrollable/severe hemorrhage • Open chest/abdominal wounds • Severe head injury • Severe medical problems • Shock • AMS
- 28. Pt Categorization Deceased • Black- Deceased • Definition • Pt found without signs of life • Obvious mortal injuries • Pt Diagnosis • Pt who have expired • Pt with injuries incompatible with survival
- 29. Patient 1 • Airway open • Respirations 20 bpm • Radial pulses present • Minor abrasions to arm/hands • Pt is walking • Green
- 30. Patient 2 • Airway is open • Reparations 30 • Singed nasal hairs noted • Absent radial pulses • Unable to walk • RED
- 31. Patient 3 • Airway open • Respirations 22 • Radial Pulses Present • Follows commands • Cannot walk • Burns to one arm • Yellow
- 32. Patient 4 • Unresponsive • Airway closed • No respirations with jaw thrust • Absent radial pulses • BLACK
- 33. Patient 5 • Pt responsive • Airway open • Respiratory rate 36 • Thready radial pulses • Unable to walk • Flail chest noted • RED
- 34. Patient 6 Unresponsive No respirations after jaw thrust Thready radial pulse Open femur fracture BLACK

Editor's Notes
- In normal responses four or more providers may work on a single patient - in mass casualties this ratio is reversed Scarce resource management recognizes that you do not have enough providers, equipment, vehicles, or time to provide the normal level of prehospital care. Therefore you have to use what you have to do the best you can for the greatest number of people. Available personnel must salvage the most patients they can while waiting for additional resources.
