Page 1
, CORRECT ANSWER
C- Incident Complex
RATIONALE
An incident complex is established when multiple incidents in the same vicinity are managed by a single Incident Commander or Unified
System. This organizational structure consolidates command for efficiency when incidents are geographically proximate.
Q2 QUESTION 2 OF 18
____ is an organization that is activated to address competition for resources among multiple ICPs based on the complexity of
the incident. Examples include 2 or more haz-mat spills, fires, etc.
A- Emergency Operations Center
B- Incident Management Team
C- Unified Command
D- Area Command
CORRECT ANSWER
D- Area Command
RATIONALE
Area Command is activated to manage multiple incidents, each with its own Incident Management Team, when competition for limited
resources arises due to incident complexity. This organizational structure coordinates resource allocation and strategic objectives across
these separate incidents.
Q3 QUESTION 3 OF 18
How does the use of Area Command facilitate the job of the IC and agency officials?
a) Much of the Coordination between incidentss that is typically performed by the IC is accomplished at the Area Command
level
b) Area Command determines the incident tactics, objectives, and strategies.
c) Establishing Area Command eliminates the need for a written delegation of authority.
d) Area Command replaces the incident-level ICS organizations and streamlines Incident Commander functions and tasks.
CORRECT ANSWER
a) Much of the Coordination between incidentss that is typically performed by the IC is accomplished at the Area Command level
RATIONALE
Area Command is established to manage multiple incidents that share common resources or objectives, thereby reducing the coordination
burden on individual Incident Commanders. This hierarchical structure allows for strategic-level decision-making and resource allocation
across a group of incidents, which is the key underlying concept.
Q4 QUESTION 4 OF 18
What is an advantage of activating an Area Command?
A- The role of the Incident Commander is shared by 2 or more persons
B-Allows different agencies to work together
C- Coordination Between Incidents
D- Incident Tactics, objectives, and strategies are not necessary
