    • Chapter 15 The ISO at Hazmat Incidents
    • Objectives
      • List the federal regulations that may have an impact on ISO functions at hazmat incidents
      • Define the reporting structure for an ASO-HM at a hazmat tech-level incident
      • Define the two overriding risks that the ISO must evaluate at hazmat incidents
    • Objectives (con’t.)
      • List the four control zones that need to be established at tech-level hazmat incidents
      • List the three hazmat rehab components that require close evaluation
      • List the ten federal-level components of a hazmat response site safety plan and five hazmat ancillary plans that may require ISO-signoff
    • Objectives (con’t.)
      • List five or more alarming hazards at a clandestine drug lab incident
      • List and describe the three strategic goals for the safety section at a WMD/terrorist incident
    • Introduction
      • Hazmat incidents: most regulated of all incidents to which fire departments respond
        • ISO assignment at a hazmat technician-level incident is mandatory
        • ISO should be aware of CFRs regarding hazmat incidents
        • If ISO does not have required technician competencies (NFPA 472), an ASO-HM should be appointed
    • Introduction (con’t.)
      • Assistant safety office-hazmat (ASO-HM)
        • Meets or exceeds NFPA 472 requirements for Hazardous Materials Technician
        • Trained in ISO responsibilities as they relate to hazmat response
        • Fulfills safety functions for technician-level components of incident
        • Works with ISO, hazmat directors, technical specialists, and industry representatives
    • Figure 15-1 The ASO-HM may actually be working with three or more persons.
    • ISO General Duties at the Hazmat Incident
      • Be familiar with NFPA 471: Recommended Practices for Responding to Hazardous Materials Incidents
      • Ensure initial zone and isolation efforts are in place upon arrival and assignment
      • Take a strategic approach
        • Interface with other command staff members
        • Maintain position at command post
    • Monitoring Issues at Hazmat Incidents
      • Risk
        • Liability: is hazmat team entry warranted?
        • Risk communication: established risk guidelines
      • Operational effectiveness
        • Rely on ASO-HM to evaluate technician operations
        • Other ASOs evaluate support activities
        • Preplan action plan prior to operations
    • Personal Safety System Issues at Hazmat Incidents
      • Accountability systems
        • Two systems: hazmat team and support responders
        • Encourage cross-communication
        • ISO deals with strategic accountability
        • ASOs deal with tactical accountability
    • Personal Safety System Issues Hazmat Incidents (con’t.)
      • Control zones
        • IDLH zone
        • No-entry zone (including collapse zone)
        • Support zone
        • Contamination reduction zone
          • Decontamination takes place
          • Safe refuge area for contaminated persons who have left the IDLH zone
    • Figure 15-3 Simple diagrams can help responders understand zone areas and travel paths.
    • Personal Safety System Issues Hazmat Incidents (con’t.)
      • Control zones (con’t.)
        • Use simple diagrams that include travel pathways and gateways between zones
        • ASO-HMs should verify appropriate level of PPE in each zone
        • Personnel moving from one zone to another should follow prescribed pathway
        • Check personnel before leaving contamination zone
    • Personal Safety System Issues Hazmat Incidents (con’t.)
      • Radio Transmissions
        • Multiple radio types and frequencies
        • Backup communication systems
          • Hand signals
          • Message boards
          • Tag-line signals
          • Spontaneous system on-scene for specific needs
    • Personal Safety System Issues Hazmat Incidents (con’t.)
      • Rehab
        • Medical monitoring
          • Establish baseline before technician stabilization efforts
        • Sanitation needs
          • Best hazard mitigation approach is separation
        • Food service
          • Distance from working areas
          • Cleanliness (further decon)
    • Defining Other Needs at Hazmat Incidents
      • Traffic
        • Roadway, railway, air, and waterway: basic approach to traffic issues is to get rid of them
        • For people, define:
          • Specific shuttle pathways
          • Escape zones
          • Zone transition gateways
    • Defining Other Needs at Hazmat Incidents (con’t.)
      • Need for ISO assistance
        • ASO-HM
        • One or more ASOs
        • Technical specialists
        • Corporate risk managers
        • Process experts
        • Public health representatives
        • Department HSO or infection control officer
    • Applying the ISO Action Model at Hazmat Incidents
      • Risk evaluation at the hazmat incident
        • ISO and ASO-HM must strive to agree on overall risk profile
        • ISO may need to communicate an acceptable risk profile to nonfire service personnel
        • Pace: slow, methodical, and intellectual approach
    • Figure 15-4 A slow, methodical, and intellectual approach is the best pace for hazmat incidents.
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Recon evaluation at the hazmat incident
        • Confirm initial zoning and isolation upon arrival and assignment
        • Verify that defined zones and gateways are appropriate
        • ASO-HM should consult a technical reference specialist as necessary
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Recon evaluation (con’t.)
        • Define the principal hazard
          • Dictated by the chemical involved
        • Define environmental integrity
          • Weather, infrastructure stability, container condition, hazardous energy
        • Define physical surroundings
          • Location defines impact of surroundings
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Recon evaluation (con’t.)
        • Crew exposure to hazards
          • Physical hazards +- Chemical properties + Crew mitigation efforts = Crew hazard exposure
          • ASO-HM in best position to evaluate tools, teams, and rapid withdrawal factors
          • Rapid intervention is far from rapid at hazmat incidents: ensure clear direction for activation
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Resource evaluation at the hazmat incident
        • Time
          • On-scene time may not be practical: manage impacts of time passage
          • Reflex time for any unplanned event is delayed
        • Personnel
          • Determine adequate training for task
        • Equipment
          • May need on-the-spot training for specialized equipment
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Report issues at the hazmat incident
        • Tech-level stabilization effort requires formal delivery and development of
          • Written site safety plan
          • Safety briefings
        • 15-minute rule for face-to-face communication is impractical
          • Keep unit log for documentation
          • Hazmat documentation not subject to statute of limitations
    • Applying the ISO Action Model at Hazmat Incidents (con’t.)
      • Report issues (con’t.)
        • Federal requirements for site safety plan include:

    • Unique Considerations at the Hazmat Incident (con’t.)
      • Weapons of mass destruction
        • Develop local WMD plan that addresses ISO functions until IMT takes over
        • ISO initially coordinates:
          • Quick in/quick out approach for immediate rescues
          • Adopt a back off posture after rescue
          • Isolation of victims and exposed firefighters
          • Staging out of sight as much as possible

          • Gather RECON and threat information
          • Analyze options: lean towards the worst case
          • Develop a safety action plan across organizational boundaries
          • Expand role into manageable parts
          • Address health and safety issues prior to IMT arrival
    • Figure 15-5 Expanding the ISO function into units can help at WMD incidents. ISO units are not currently NIMS compliant.
