Common indicators may include the area (location) involved; threat to life, environment and property; political sensitivity, organizational complexity, jurisdictional boundaries, values at risk, and weather. Most indicators are common to all incidents, but some may be unique to a particular type of incident. The following are common contributing indicators for each of the five complexity types.
TYPE 5 INCIDENT COMPLEXITY INDICATORS
General Indicators Span of Control Indicators
• Incident is typically terminated or concluded (objective met) within a short time once resources arrive on scene
• For incidents managed for resource objectives, minimal staffing/oversight is required
• One to five single resources may be needed
• Formal Incident Planning Process not needed
• Written Incident Action Plan (IAP) not needed
• Minimal effects to population immediately surrounding the incident
• Critical Infrastructure, or Key Resources, not adversely affected
• Incident Commander (IC) position filled
• Single resources are directly supervised by the IC
• Command Staff or General Staff positions not needed to reduce workload or span of control
TYPE 4 INCIDENT COMPLEXITY INDICATORS
General Indicators Span of Control Indicators
• Incident objectives are typically met within one operational period once resources arrive on scene, but resources may remain on scene for multiple operational periods
• Multiple resources (over 6) may be needed
• Resources may require limited logistical support
• Formal Incident Planning Process not needed
• Written Incident Action Plan (IAP) not needed
• Limited effects to population surrounding incident
• Critical Infrastructure or Key Resources may be adversely affected, but mitigation measures are uncomplicated and can be implemented within one Operational Period
• Elected and appointed governing officials, stakeholder groups, and political organizations require little or no interaction
• IC role filled
• Resources either directly supervised by the IC or supervised through an ICS Leader position
• Task Forces or Strike Teams may be used to reduce span of control to an acceptable level
• Command Staff positions may be filled to reduce workload or span of control
• General Staff position(s) may be filled to reduce workload or span of control
TYPE 3 INCIDENT COMPLEXITY INDICATORS
General Indicators Span of Control Indicators
• Incident typically extends into multiple operational periods
• Incident objectives usually not met within the first or second operational period
• Resources may need to remain at scene for multiple operational periods, requiring logistical support
• Numerous kinds and types of resources may be required
• Formal Incident Planning Process is initiated and followed
• Written Incident Action Plan (IAP) needed for each Operational Period
• Responders may range up to 200 total personnel
• Incident may require an Incident Base to provide support
• Population surrounding incident affected
• Critical Infrastructure or Key Resources may be adversely affected and actions to mitigate effects may extend into multiple Operational Periods
• Elected and appointed governing officials, stakeholder groups, and political organizations require some level of interaction
• IC role filled
• Numerous resources supervised indirectly through the establishment and expansion of the Operations Section and its subordinate positions
• Division Supervisors, Group Supervisors, Task Forces, and Strike Teams used to reduce span of control to an acceptable level
• Command Staff positions filled to reduce workload or span of control
• General Staff position(s) filled to reduce workload or span of control
• ICS functional units may need to be filled to reduce workload
TYPE 2 INCIDENT COMPLEXITY INDICATORS
General Indicators Span of Control Indicators
• Incident displays moderate resistance to stabilization or mitigation and will extend into multiple operational periods covering several days
• Incident objectives usually not met within the first several Operational Periods
• Resources may need to remain at scene for up to 7 days and require complete logistical support
• Numerous kinds and types of resources may be required including many that will trigger a formal demobilization process
• Formal Incident Planning Process is initiated and followed
• Written Incident Action Plan (IAP) needed for each Operational Period
• Responders may range from 200 to 500 total
• Incident requires an Incident Base and several other ICS facilities to provide support
• Population surrounding general incident area affected
• Critical Infrastructure or Key Resources may be adversely affected, or possibly destroyed, and actions to mitigate effects may extend into multiple Operational Periods and require considerable coordination
• Elected and appointed governing officials, stakeholder groups, and political organizations require a moderate level of interaction
• IC role filled
• Large numbers of resources supervised indirectly through the expansion of the Operations Section and its subordinate positions
• Branch Director position(s) may be filled for organizational or span of control purposes
• Division Supervisors, Group Supervisors, Task Forces, and Strike Teams used to reduce span of control
• All Command Staff positions filled
• All General Staff positions filled
• Most ICS functional units filled to reduce workload
TYPE 1 INCIDENT COMPLEXITY INDICATORS
General Indicators Span of Control Indicators
• Incident displays high resistance to stabilization or mitigation and will extend into numerous operational periods covering several days to several weeks
• Incident objectives usually not met within the first several Operational Periods
• Resources may need to remain at scene for up to 14 days, require complete logistical support, and several possible personnel replacements
• Numerous kinds and types of resources may be required, including many that will trigger a formal demobilization process
• DOD assets, or other nontraditional agencies, may be involved in the response, requiring close coordination and support
• Complex aviation operations involving multiple aircraft may be involved
• Formal Incident Planning Process is initiated and followed.
• Written Incident Action Plan (IAP) needed for each Operational Period
• Responders may range from 500 to several thousand total
• Incident requires an Incident Base and numerous other ICS facilities to provide support
• Population surrounding the region or state where the incident occurred is affected
• Numerous Critical Infrastructure or Key Resources adversely affected or destroyed. Actions to mitigate effects will extend into multiple Operational Periods spanning days or weeks and require long-term planning and considerable coordination
• Elected and appointed governing officials, stakeholder groups, and political organizations require a high level of interaction
• IC role filled
• Large numbers of resources supervised indirectly through the expansion of the Operations Section and its subordinate positions
• Branch Director Position(s) may be filled for organizational or span of control purposes
• Division Supervisors, Group Supervisors, Task Forces, and Strike Teams used to reduce span of control
• All Command Staff positions filled and many include assistants
• All General Staff positions filled and many include deputy positions
• Most or all ICS functional units filled to reduce work
