ICS Organizational Structure and Elements

Introduction to ICS

The Incident Command System (ICS) is a standardized on-scene emergency management system designed to enable effective and efficient incident management by integrating a combination of facilities, equipment, personnel, procedures, and communications operating within a common organizational structure. It was developed in the 1970s following a series of catastrophic wildfires in California to address coordination problems between interagency responses.

ICS is used by all levels of governmentfederal, state, tribal, and localas well as by many private-sector and nongovernmental organizations. It provides a flexible, scalable, and adaptable framework for managing incidents of any type or size, from minor emergencies to major disasters.

ICS Command Structure

At the top of the ICS organizational structure is the Incident Commander (IC), who is responsible for overall management of the incident. The IC establishes objectives and priorities and has overall responsibility at the incident or event.

Command Staff

The Command Staff reports directly to the Incident Commander and includes:

• Public Information Officer (PIO): Serves as the conduit for information to internal and external stakeholders, including the media and other agencies.
• Safety Officer (SOFR): Monitors safety conditions and develops measures for ensuring the safety of all assigned personnel.
• Liaison Officer (LNO): On-scene contact for representatives from other assisting agencies and organizations.

General Staff

The General Staff is responsible for the functional aspects of the incident management. Each section has a Chief who reports directly to the Incident Commander. The General Staff sections include:

Operations Section

The Operations Section is responsible for all tactical operations at the incident or event. The Operations Chief directs and coordinates all tactical operations. This section includes:

• Staging Area Manager: Manages temporary location where personnel and equipment are kept while awaiting assignment.
• Divisions and Groups: Divisions are established to divide an incident geographically, while Groups are established to divide an incident functionally.
• Strike Teams and Task Forces: Strike Teams consist of a specified number of resources of the same type and capability, while Task Forces consist of combinations of different resources.

Planning Section

The Planning Section collects, evaluates, and disseminates information about the incident. The Planning Chief coordinates the overall planning process. This section includes:

• Documentation Unit: Collects, records, and documents all information about the incident.
• Demobilization Unit: Assists in ensuring orderly equipment and personnel release.
• Resources Unit: Tracks all resources assigned to the incident.
• Situation Unit: Collects and analyzes information on the current situation.

Logistics Section

The Logistics Section provides facilities, services, and material support for the incident. The Logistics Chief is responsible for providing all support needs. This section includes:

• Supply Unit: Supplies, orders, and receives resources.
• Facilities Unit: Sets up and maintains facilities.
• Ground Support Unit: Provides ground transportation.
• Food Unit: Provides food services to incident personnel.
• Communications Unit: Provides communication services and equipment.
• Medical Unit: Provides emergency medical care to incident personnel.

Finance/Administration Section

The Finance/Administration Section tracks incident costs and provides procurement, reimbursement, and financial oversight. The Finance/Administration Chief oversees this section. This section includes:

• Time Unit: Records time for incident personnel.
• Procurement Unit: Handles all equipment and supply procurement.
• Compensation/Claims Unit: Administers financial matters related to compensation and claims.
• Cost Unit: Records all costs associated with the incident.

ICS Management Characteristics

ICS is built on several key management characteristics that ensure effective incident management:

• Common Terminology: Use of common terms ensures clear communication across agencies and disciplines.
• Modular Organization: ICS structure can expand or contract to meet incident needs.
• Management by Objectives: Establishing specific, measurable objectives for the incident.
• Incident Action Planning: Development of written plans to guide incident activities.
• Manageable Span of Control: Optimal span of control ranges from 3 to 7 subordinates per supervisor.
• Pre-designated Incident Locations: Facilities are designated to support incident management.
• Comprehensive Resource Management: Processes to categorize, order, track, and mobilize resources.
• Integrated Communications: Common operating plans, frequencies, and terminology.
• Establishment and Transfer of Command: Clear process for command transfer or designation.
• Information and Intelligence Management: Process for gathering and sharing incident information.

ICS Facilities

ICS designates specific facilities for incident management activities:

• Incident Command Post (ICP): Location from which the Incident Commander oversees all incident operations.
• Staging Area: Temporary location where personnel and equipment await tactical assignment.
• Base: Location from which primary logistics and administrative functions are coordinated and administered.
• Camp: Location where resources may be kept to support incident operations.
• Helibase: Location from which helicopters engage in incident operations.
• Helispot: Any designated location where helicopters can safely take off and land.

Common Responsibilities

All ICS personnel share certain common responsibilities:

• Follow the incident chain of command
• Communicate effectively with subordinates and supervisors
• Know and follow the Incident Action Plan
• Attend briefings as required by their position
• Ask for direction when needed
• Implement tactics or strategies as directed
• Maintain awareness of safety hazards and concerns
• Keep accurate documentation as required by their position

Implementation Considerations

Successful ICS implementation requires:

• NIMS Compliance: Alignment with National Incident Management System principles.
• Training: Appropriate ICS position training for all personnel.
• Interoperability: Ability to work effectively with other agencies and jurisdictions.
• Flexibility: Ability to adapt structure to meet incident requirements.
• Unity of Effort: Collaborative approach among all responding agencies.

Benefits of ICS

The Incident Command System provides numerous benefits for emergency response and incident management:

• Provides a standardized approach to incident management
• Ensures efficient use of resources through comprehensive resource management
• Enables effective interagency coordination and cooperation
• Reduces duplication of efforts
• Ensures safety of both responders and the public
• Creates a unified chain of command
• Facilitates clear communication through common terminology
• Provides accountability through documentation procedures
• Improves strategic planning through established objectives and action planning
• Enhances adaptability to any type of incident or emergency

Conclusion

The Incident Command System provides a flexible and scalable framework for managing incidents of any type or size. Through its organized structure of Command and General Staff positions, designated facilities, and clear management principles, ICS enables effective multi-agency coordination, efficient resource utilization, and strategic planning in emergency situations. Understanding ICS organizational structure and elements is essential for emergency personnel, responders, and anyone involved in incident management operations.
