⩥ Incident Action Plan (IAP).
Answer: Incident action planning guides incident management activities.
Incident Action Plans (IAPs):
- Record and communicate incident objectives, tactics, and assignments
for operations and support
- Are recommended for all incidents
- Are not always written, but a written IAP is increasingly important
when an incident or activation:
* Is likely to extend beyond one operational period
* Becomes more complex
* Involves multiple jurisdictions or agencies
⩥ integrated communications.
Answer: Integrated communications allow units from diverse agencies
to connect, share information and achieve situational awareness.
,Incident managers facilitate communications through the development
and use of:
- A common communications plan
- Interoperable communications processes and systems
- Systems that include both voice and data links
Integrated Communications Planning occurs both before and during an
incident to provide equipment, systems, and protocols needed to achieve
integrated voice and data communications.
⩥ modular organization.
Answer: Organizational structures for incident management (ICS and
EOCs) are modular, meaning that they are each building blocks that are
put in place as needed based on an incident's size, complexity, and
hazards.
The ICS Commander and EOC Director are responsible for the
establishment and expansion of the modular organization based on the
specific requirements for their incident.
As incident complexity increases, the organizational structure expands
and management responsibilities are further divided.
The number of management, supervisory, and support positions expand
as needed to meet the needs of the incident.
, ⩥ Manageable Span of Control.
Answer: The span of control refers to the number of subordinates that
directly report to a supervisor.
Maintaining an appropriate span of control ensures effective incident
management by enabling supervisors to:
- Direct and supervise subordinates
- Communicate with and manage resources
The optimal span of control for incident management is one supervisor
to five subordinates; however, the 1:5 ratio is only a guideline, and
effective incident management often calls for different ratios.
When a supervisor's span of control becomes unmanageable, they can
assign subordinate supervisors or redistribute subordinates to manage
portions of the organization in order to regain a manageable span of
control.
The span of control can change based on:
- Type of incident
- Nature of the task
- Existing hazards and safety factors
- Distances between personnel and resources
