1 Hazardous Materials

2 HAZMAT Definition (USDOT) Any substance which may pose an unreasonable risk to health and safety of operating or emergency personnel, the public, and/or the environment if not properly controlled during handling, storage, manufacture, processing, packaging, use, disposal, or transportation. Any substance which may pose an unreasonable risk to health and safety of operating or emergency personnel, the public, and/or the environment if not properly controlled during handling, storage, manufacture, processing, packaging, use, disposal, or transportation.

3 Requirements and Standards OSHA: CFR OSHA: CFR EPA: 40 CFR 311 EPA: 40 CFR 311 NFPA: Standard 473 (Standard for Competencies of EMS Personnel Responding to Hazardous Materials Incidents) NFPA: Standard 473 (Standard for Competencies of EMS Personnel Responding to Hazardous Materials Incidents)

50 Medical Monitoring & Rehab A primary role of EMS A primary role of EMS Entry team personnel should have annual physicals with baseline vitals on file Entry team personnel should have annual physicals with baseline vitals on file Monitoring of crews prior to entering and after working within the warm and hot zones. Monitoring of crews prior to entering and after working within the warm and hot zones.

51 HAZMAT Zones Hot Zone Contamination Present Appropriate PPE Limited number of personnel Everything inside considered contaminated Warm Zone Contamination Control Zone Appropriate PPE Decon Corridor Life-Saving Emergency Care Cold Zone CP Location Treatment/Transport Areas Staging Medical Monitoring/Rehab

52 Decontamination

53 Decon Decision Making Fast Break Fast Break Long Term Long Term

54 Fast Break Quick decisions to prevent rescuer, equipment contamination Quick decisions to prevent rescuer, equipment contamination Used on incidents with: Used on incidents with: –Patients who have self-rescued –Critical patients out of hot zone needing immediate care –Unknown materials –Potentially life-threatening materials

55 Fast Break Do NOT expose yourself Do NOT expose yourself Contain, isolate patients Contain, isolate patients Remove clothing, if possible by having them undress themselves Remove clothing, if possible by having them undress themselves Wash with large amounts of water Wash with large amounts of water Wrap completely in blankets (human burrito) Wrap completely in blankets (human burrito)

56 Fast Break What are the risks associated with immediate care? What are the risks associated with immediate care? What are the benefits of the patient receiving immediate care? What are the benefits of the patient receiving immediate care?

57 Transport Considerations Patients field decontaminated are only semi-decontaminated Patients field decontaminated are only semi-decontaminated May harbor latent contaminants, may outgas contaminants in body fluids May harbor latent contaminants, may outgas contaminants in body fluids Limit number of ambulances used in transport Limit number of ambulances used in transport Remove non-essential equipment Remove non-essential equipment Wrap patient in plastic sheeting, blankets Wrap patient in plastic sheeting, blankets Cover floor with plastic sheeting Cover floor with plastic sheeting

58 Transport Considerations Better Dirty and Alive than Clean and Dead!

59 Transport Considerations Do NOT assume your hospitals are equipped to handle contaminated patients

60 Transport Considerations Preplan transport of contaminated patients to hospitals Preplan transport of contaminated patients to hospitals –Hospitals may want contaminated patients delivered to location other than usual ER entrance –Hospitals need adequate warning to prepare to receive these patients. Alert should come when first EMS unit arrives at the scene.

61 WMD & Terrorism

62 Terrorism A violent act or act dangerous to human life, in violation of the criminal laws of the U.S. or any segment to intimidate or coerce a government, the civilian population or any segment thereof, in furtherance of political or social objectives. A violent act or act dangerous to human life, in violation of the criminal laws of the U.S. or any segment to intimidate or coerce a government, the civilian population or any segment thereof, in furtherance of political or social objectives.

63 Terrorism Targets Potential Targets Potential Targets –Public buildings –Multinational HQs –Shopping centers –Workplaces –Public assembly places –Places of worship –Schools

64 Terrorism Targets Preplan potential targets Preplan potential targets Multiple patients with similar signs, symptoms = High index of suspicion Multiple patients with similar signs, symptoms = High index of suspicion Consider secondary device, attack risk Consider secondary device, attack risk Think: Think: –Occupancy or location –Type of event –Timing of event –On-scene warning signs

65 WMD Biological Nuclear Incendiary Chemical Explosives

66 Protective Measures All forms of protection can be defined in terms of: TimeDistanceShielding

67 Considerations Acts of terrorism are criminal acts and will fall under the jurisdiction of the FBI. Acts of terrorism are criminal acts and will fall under the jurisdiction of the FBI. ICS is pivotal in the successful mitigation of any terrorist act. ICS is pivotal in the successful mitigation of any terrorist act. Self safety is foremost consideration at all times.
