Study Notes

Sectoring in Incident Management System

Sectoring is a tool that allows the Incident Commander (IC) to group personnel and resources into manageable units at an emergency incident, based on geographical or functional tasks.

Rationale for Sectoring

Reduces the span of control for the IC
Provides an effective command structure
Reduces radio traffic, enabling the IC to focus on overall strategy and resource allocation

Sector Designation

Sectors are designated by geographic position or functional task
Geographic Designations:
- Main entrance of a building is designated as Alpha Sector
- Remaining sides are designated phonetically in a clockwise manner
- In multi-storey occupancies, Sectors are indicated by floor numbers (e.g., Sector 5 for the 5th floor)
Functional Designations:
- Assigned according to tasks, such as Rehab, Staging, Fire Control, Ventilation, etc.

Sector Officer Radio Designation

Sector Officer radio designations are abbreviated to reduce radio traffic
Examples:
- Incident Safety Officer: Safety
- Staging Officer: Staging
- Rehabilitation Officer: Rehab

Sector Officer Responsibilities and Duties

Responsible for command and control of their Sector
Carry out tactical objectives assigned by Command
Advise Command of their location and readiness
Ensure accountability and designate a staging area
Designate a controlled area and assign an Entry Control person
Notify Command when additional resources are needed
Set up air supply and ensure adequate resources
Coordinate personnel re-assignment through Command
Ensure personnel operate in a safe and effective manner
Control personnel assigned to Rehab Sector
Conduct and report PAR status of their Sector

Work Cycle Rotation

Set up in sectors where tasks cannot be interrupted
Three crews assigned per task:
- 1st crew deployed- deployed in hot zone
- 2nd crew "On Deck"- ready for assignment
- 3rd crew available at Sector Rehab- just exited hot zone,
Teams rotate through these positions until two cylinders are depleted, then assigned to Incident Rehab Sector
Advantages:
- Having personnel ready for immediate deployment
- Providing immediate resources for MAYDAY or RIT
- Reduces time traveling between Sectors
Challenges:
- Getting adequate personnel in place to support the work cycle
- Setting up Air Supply and Accountability

Assignment of Sectors

Sectors can be assigned based on:
- Span of control improvement for the IC
- Large or complex incidents
- Presence of special hazards
Typically, a Sector Officer's span of control does not exceed a ratio of five to one
Medical Sector:
- Established when patient care requirements are present
- Ensure Command receives updates on patient status
