The Incident Command System (ICS) is a standardized approach to
incident management that: - ANSWER-Is used for all kinds of incidents
by all types of organizations and at all levels of government; ICS is
applicable to small incidents as well as large and complex ones.
Can be used not only for emergencies but also for planned events.
Enables a coordinated response among various jurisdictions and
agencies.
Establishes common processes for incident-level planning and resource
management.
,Allows for the integration of resources (such as facilities, equipment,
personnel) within a common organizational structure.
When is ICS Used? - ANSWER-can be used to manage any type of
incident, including a planned event (e.g., the Olympics, the Governor's
inauguration, state fairs, a local parade, etc.). The use of ICS is
applicable to all types of incidents, regardless of their size or cause.
Comprehensive Resource Management - ANSWER-standard
mechanisms to identify requirements, order and acquire, mobilize,
track and report, demobilize, and reimburse and restock resources such
as personnel, teams, facilities, equipment and supplies.
Key resource management activities include: - ANSWER-~resource
identification & typing
~qualification, certification & credentialing personnel
~planning for resources
~acquiring, storing & inventorying resources
Integrated Communications - ANSWER-are facilitated through the
development and use of a common communications plan and
interoperable communication processes and systems that include voice
and data links.
Integrated Communications are necessary to: - ANSWER-~maintain
connectivity
,~achieve situational awareness
~facilitate information sharing
Span of control refers to the fact that a supervisor can effectively
manage an unlimited amount of resources. - ANSWER-FALSE: Span of
control refers to the fact that a supervisor can effectively manage an
unlimited amount of resources.
Explanation: If too much responsibility is given to the supervisor, the
span of control may become unmanageable.
In part, comprehensive resource management describes standard
mechanisms used to identify requirements and acquire, mobilize, track,
and demobilize resources. - ANSWER-TRUE: In part, comprehensive
resource management describes standard mechanisms used to identify
requirements and acquire, mobilize, track, and demobilize resources.
Explanation: Comprehensive resource management describes standard
mechanisms to identify requirements and order and acquire, mobilize,
activate, track and report, recover and demobilize, reimburse for, and
inventory resources such as personnel, equipment, teams, and
facilities.
Integrated communications are necessary to achieve situational
awareness. - ANSWER-TRUE: Integrated communications are necessary
to achieve situational awareness.
, Explanation: Integrated communications are necessary to maintain
connectivity, achieve situational awareness, and facilitate information
sharing.
Establishment and Transfer of Command - ANSWER-The command
function must be clearly established from the beginning of incident
operations. The agency with primary jurisdictional authority over the
incident designates the individual at the scene responsible for
establishing command. When command is transferred, the process
must include a briefing that captures all essential information for
continuing safe and effective operations
Unified Command - ANSWER-there is no single "Commander." Instead
the Unified Command manages the incident through jointly approved
objectives.
Unified Command allows agencies with different legal, geographic, and
functional responsibilities to work together effectively without affecting
individual agency authority, responsibility, or accountability.
Unified Command is typically established when no single jurisdiction,
agency or organization has the authority and/or resources to manage
the incident on its own.
