,SECTION I: INCIDENT COMMAND SYSTEM (ICS) & ACCOUNTABILITY (Questions 1-30)
Question 1
What is the primary purpose of establishing Incident Command at an emergency scene?
A) To take control of the scene and ensure safety
B) To coordinate media and public relations
C) To delegate all tasks to arriving units
D) To minimize accountability and documentation
Answer: A) To take control of the scene and ensure safety
Rationale: Establishing Incident Command ensures a unified, organized approach to managing
the incident, prioritizing safety and effective response. ICS provides a clear chain of command
and accountability structure.
Question 2
Which of the following best describes a 360-degree scene size-up?
A) Assessing only the front of the building for hazards
B) Conducting a thorough assessment around the entire incident perimeter
C) Only checking the interior for victims
D) Walking around to take photographs for documentation
Answer: B) Conducting a thorough assessment around the entire incident perimeter
Rationale: A 360-degree size-up involves evaluating all sides of the scene to identify hazards,
access points, and rescue potential. This comprehensive assessment is critical for situational
awareness and safe operations.
Question 3
When selecting an offensive fire suppression strategy, the initial decision is based on which
factor?
A) The availability of personnel only
B) The size and extent of the fire, and life safety considerations
C) The type of equipment on scene
D) The weather conditions only
Answer: B) The size and extent of the fire, and life safety considerations
Rationale: Offensive strategies are chosen when there is a reasonable chance to save lives and
the fire is still manageable, based on size-up data. The safety of occupants and firefighters is
the primary consideration.
,Question 4
During a transfer of command, the incoming officer should be briefed on all of the following
EXCEPT:
A) Current fire conditions and hazards
B) Resource status and personnel accountability
C) Personal opinions about the incident
D) Actions taken and strategic considerations
Answer: C) Personal opinions about the incident
Rationale: The transfer of command should focus on factual, operational information; personal
opinions are not appropriate for official briefings. The briefing must be objective and actionable.
Question 5
By what title or rank are the heads of the four major functional components of the ICS known?
A) Director
B) Chief
C) Officer
D) Commander
Answer: B) Chief
Rationale: The heads of the four major functional components of ICS (Operations, Planning,
Logistics, and Finance/Administration) are known as Chiefs. This follows the standard ICS
organizational structure.
Question 6
If someone is designated as a Director, what type of ICS grouping is that person supervising?
A) Division
B) Branch
C) Group
D) Strike Team
Answer: B) Branch
Rationale: In ICS, a Director supervises a Branch. Branches are established when the number
of Divisions or Groups exceeds the span of control of the Operations Section Chief.
Question 7
What is the next step in the TRI (Technical Rescue Incident) process after removal of a victim?
A) Scene stabilization
B) Transport
C) Decontamination
, D) Termination of operations
Answer: B) Transport
Rationale: After removal of a victim in a Technical Rescue Incident, the next step is transport.
This is part of the sequential TRI process that follows victim removal.
Question 8
In the FAILURE acronym used for situational awareness, what does the "R" stand for?
A) Rescue operations only
B) Rescue versus recovery mode not being considered
C) Rapid intervention team deployment
D) Risk assessment performed
Answer: B) Rescue versus recovery mode not being considered
Rationale: The FAILURE acronym is used in firefighter situational awareness training. The "R"
specifically refers to "Rescue versus recovery mode not being considered," reminding
firefighters to assess whether the incident is still in the rescue phase or has transitioned to
recovery, which significantly changes operational risk assessment.
Question 9
In the FAILURE acronym, what does the "A" stand for?
A) Additional medical problems not considered
B) Assessment of fire conditions
C) Apparatus placement
D) Accountability procedures
Answer: A) Additional medical problems not considered
Rationale: The "A" in the FAILURE acronym stands for "Additional medical problems not
considered." This reminds firefighters to consider secondary medical issues that may not be
immediately apparent during an emergency response.
Question 10
In the FAILURE acronym, what does the "I" stand for?
A) Inadequate rescue skills
B) Initial size-up completed
C) Incident command established
D) Investigation of cause
Answer: A) Inadequate rescue skills
