, Section 1: ICS Overview, History & Purpose
Q1. What is the Incident Command System (ICS)?
A) A standardized, on-scene, all-hazards approach to the command, control, and coordination of
emergency response
B) A federal law enforcement agency
C) A software program used only by fire departments
D) A funding mechanism for disaster relief
Correct Answer: A) A standardized, on-scene, all-hazards approach to the command, control, and
coordination of emergency response
Rationale: ICS is a standardized management system that allows responders from different agencies and
jurisdictions to work together effectively on incidents of any size, cause, or complexity, using a common
organizational structure and terminology.
Q2. ICS was originally developed in the 1970s primarily in response to problems encountered
during which type of incidents?
A) Large urban wildland fires in California
B) Airline hijackings
C) Nuclear power plant accidents
D) Cyberattacks on infrastructure
Correct Answer: A) Large urban wildland fires in California
Rationale: ICS grew out of the FIRESCOPE program developed after major wildland fires in California in the
1970s revealed problems with communications, organizational structure, and coordination among the many
agencies responding to the same incident.
Q3. What does NIMS stand for?
A) National Incident Management System
B) National Interagency Mutual Support
C) National Infrastructure Monitoring System
D) National Incident Media Standard
Correct Answer: A) National Incident Management System
Rationale: NIMS is the overarching national framework that provides a consistent approach for all levels of
government, the private sector, and nongovernmental organizations to work together to prevent, protect
against, respond to, recover from, and mitigate the effects of incidents.
, Q4. How does ICS relate to NIMS?
A) ICS is unrelated to NIMS
B) ICS is one component of NIMS, specifically the standardized on-scene incident management
system
C) NIMS is a subcomponent of ICS
D) ICS replaced NIMS in 2020
Correct Answer: B) ICS is one component of NIMS, specifically the standardized on-scene
incident management system
Rationale: NIMS includes several components (such as Resource Management, Communications and
Information Management, and Command and Coordination), and ICS is the specific standardized approach to
on-scene incident command and management within the broader NIMS framework.
Q5. What is meant by ICS being an 'all-hazards' system?
A) It can only be used for hazardous materials incidents
B) It is applicable to any type of incident, regardless of cause, size, or complexity
C) It applies only to natural disasters
D) It is used exclusively by federal agencies
Correct Answer: B) It is applicable to any type of incident, regardless of cause, size, or complexity
Rationale: One of the defining strengths of ICS is its flexibility -- it can be applied to a small local car accident,
a multi-day wildfire, a planned special event, or a large-scale natural disaster, using the same basic principles
and structure.
Q6. Which of the following best describes a key benefit of using ICS across multiple agencies
and jurisdictions?
A) It eliminates the need for any training
B) It provides a common organizational structure and terminology that enables effective, coordinated
response among diverse responders
C) It requires every agency to use different terminology suited to their specialty
D) It removes the need for any incident objectives
Correct Answer: B) It provides a common organizational structure and terminology that enables
effective, coordinated response among diverse responders
Rationale: Because ICS uses standardized common terminology and a predictable organizational structure,
personnel from different agencies, disciplines, and jurisdictions who have never worked together before can
integrate quickly and communicate clearly during a response.
