Question 1General (safety, health and wellness, incident management)

During interior structural firefighting in an immediately dangerous to life and health atmosphere, what does the two-in/two-out rule require?

  1. Two charged handlines in place before interior crews advance
  2. Two chief officers on scene before operations begin
  3. Two members inside and two outside before entry Correct answer.
  4. Two rapid intervention teams staged at each entrance

Explanation

OSHA respiratory protection rules and NFPA 1500 require that members enter an IDLH atmosphere in teams of at least two, with at least two additional members outside who are equipped and ready to perform rescue. The outside members must be able to account for and assist the interior crew at all times.

Question 2General (safety, health and wellness, incident management)

Under the Incident Command System, unity of command means that each individual reports to:

  1. One, and only one, supervisor Correct answer.
  2. The incident commander through the planning section
  3. Whichever supervisor is nearest the work area
  4. The senior officer of the agency with jurisdiction

Explanation

Unity of command is the ICS principle that every member answers to a single designated supervisor, which prevents conflicting orders and unclear responsibility. When it is violated, members may receive contradictory direction and accountability breaks down.

Question 3General (safety, health and wellness, incident management)

A personal alert safety system (PASS) device worn by a firefighter is designed to:

  1. Emit a loud alarm when the wearer stops moving Correct answer.
  2. Display the pressure remaining in the SCBA cylinder
  3. Warn when ambient temperature exceeds 500 degrees Fahrenheit
  4. Provide a backup radio channel for mayday transmissions

Explanation

An integrated PASS device senses motion and activates a pre-alarm after roughly 20 seconds of inactivity, escalating to a full audible alarm at about 30 seconds. It can also be manually activated by a member who becomes trapped or disoriented so that rescuers can locate the member by sound.

Question 4General (safety, health and wellness, incident management)

What span of control does NIMS describe as effective for a supervisor at an incident?

  1. Five to twelve, with eight being optimal
  2. Two to four, with three being optimal
  3. Three to seven, with five being optimal Correct answer.
  4. Four to ten, with six being optimal

Explanation

NIMS describes a sound span of control as three to seven subordinates reporting to one supervisor, with five considered optimal. A supervisor who exceeds that range should divide the workload by creating additional divisions, groups, or branches.

Question 5General (safety, health and wellness, incident management)

Under NFPA 1981, an SCBA low-air alarm must activate when cylinder pressure falls to what level?

  1. Approximately 33 percent of capacity Correct answer.
  2. Approximately 20 percent of capacity
  3. Approximately 10 percent of capacity
  4. Approximately 50 percent of capacity

Explanation

NFPA 1981 requires the end-of-service-time indicator to sound when about one third of the cylinder's rated capacity remains. That threshold gives the wearer warning time to exit the hazard zone before the air supply is exhausted.

Question 6General (safety, health and wellness, incident management)

NFPA 1500 requires a hearing conservation program when firefighter noise exposure exceeds what level?

  1. 105 dBA regardless of duration
  2. 95 dBA sustained for ten minutes or more
  3. 85 dBA averaged over an eight-hour period Correct answer.
  4. 65 dBA at any point during the shift

Explanation

The fire service hearing conservation threshold follows the 85 dBA time-weighted average over an eight-hour workday. Programs include noise monitoring, audiometric testing, and provision of hearing protection.

Question 7General (safety, health and wellness, incident management)

The primary purpose of a personnel accountability system at an incident is to:

  1. Record the air remaining in each member's cylinder
  2. List the order in which companies enter the structure
  3. Identify who is on scene and their assignments Correct answer.
  4. Document each member's training and certification

Explanation

An accountability system tracks which members are at the incident and where they are working so that a rapid and complete accounting can be made at any time. That information drives the decision to initiate a personnel accountability report or a mayday search.

Question 8General (safety, health and wellness, incident management)

Which situation requires a firefighter to transmit a mayday?

  1. Air cylinder pressure has dropped to 50 percent
  2. The company officer orders the crew to back out of the structure
  3. The fire is not yet located after ten minutes of searching
  4. The firefighter is trapped by collapsed debris Correct answer.

Explanation

A mayday is transmitted for self-survival emergencies such as being trapped, lost, disoriented, entangled, out of air, or seriously injured. Routine tactical changes and normal air consumption milestones do not meet the criteria.

Question 9General (safety, health and wellness, incident management)

A rapid intervention crew staged at a working fire should:

  1. Provide rehab and medical monitoring at the entry point
  2. Assist with fire attack once the primary search is complete
  3. Monitor radio traffic and keep the accountability board updated
  4. Stand by to rescue trapped members and perform no other duties Correct answer.

Explanation

The rapid intervention crew is dedicated solely to locating and rescuing firefighters in distress, with its own tools and equipment staged at the entry point. Assigning it other tasks delays deployment and defeats its purpose.

Question 10General (safety, health and wellness, incident management)

At a structural fire, a supervisor designated as Division 3 is organized by:

  1. Type of resource assigned, such as ladder companies
  2. Agency or jurisdiction supplying the resources
  3. Functional responsibility such as ventilation
  4. Geographic area within the incident Correct answer.

Explanation

Divisions divide an incident by physical or geographic area, such as a floor of a building or a side of the structure. Functional responsibilities and resource types are organized as groups instead.

Question 11General (safety, health and wellness, incident management)

When command of an incident is transferred, the incoming incident commander must:

  1. Restart the planning cycle for the next operational period
  2. Receive a briefing covering incident status, objectives, and actions taken Correct answer.
  3. Announce the change on a dedicated radio channel to all media
  4. Reassign all company officers to new positions

Explanation

A transfer of command requires an effective briefing that covers the incident situation, objectives, actions taken, current organization, resources assigned, and safety concerns. The incoming commander then notifies all personnel that command has changed.

Question 12General (safety, health and wellness, incident management)

According to NFPA 1584, a member in rehabilitation should not be released back to duty until the heart rate is at or below which value?

  1. 100 beats per minute Correct answer.
  2. 110 beats per minute
  3. 140 beats per minute
  4. 120 beats per minute

Explanation

NFPA 1584 lists a heart rate of 100 beats per minute or less as one criterion for release from rehabilitation, along with normal respirations, adequate oxygen saturation, and absence of chest pain or other symptoms. Members who do not meet the criteria need further evaluation and rest.

Question 13General (safety, health and wellness, incident management)

A firefighter sustains a needlestick while providing patient care. The member's first action should be to:

  1. Cover the wound and finish the call before reporting
  2. Wait for the hospital to test the patient first
  3. Wash the site with soap and water, then report it Correct answer.
  4. Squeeze the wound to express blood, then bandage it

Explanation

Immediate washing or flushing of the exposed site limits transmission, after which the exposure must be reported under the department's exposure control plan so that medical evaluation and post-exposure prophylaxis can be started promptly. Delaying the report extends the window for preventive treatment.

Question 14General (safety, health and wellness, incident management)

A defusing following a critical incident is best described as:

  1. A formal critique of the incident's command decisions
  2. A written report submitted to the agency administrator
  3. A short session held within hours of the incident Correct answer.
  4. A structured debrief held several weeks after the event

Explanation

A defusing is a brief, small-group session conducted within hours of the event to reduce acute distress and identify members who need further support. It is not an investigation or performance critique, and it precedes the more structured debriefing held later.

Question 15General (safety, health and wellness, incident management)

Which statement best describes the purpose of an Incident Action Plan?

  1. It states the objectives and tactics for a given operational period Correct answer.
  2. It records the cause and origin findings from the investigation
  3. It replaces the need for a written incident organization chart
  4. It lists every resource that could be ordered through mutual aid

Explanation

The Incident Action Plan documents the incident objectives, strategies, tactics, and supporting information for one operational period. It gives responders a common set of written objectives and is updated as the incident progresses.

Question 16General (safety, health and wellness, incident management)

The primary purpose of an NFPA 1582 medical evaluation is to:

  1. Satisfy insurance requirements for apparatus operators
  2. Establish a baseline for workers' compensation claims
  3. Determine whether a member can perform essential job tasks Correct answer.
  4. Certify a member's fitness for promotion to officer rank

Explanation

NFPA 1582 sets requirements for the occupational medical evaluation of firefighters to determine whether a member can perform essential job tasks without undue medical risk. The process also identifies conditions that may require accommodation or restricted duty.

Question 17General (safety, health and wellness, incident management)

Which incident is best managed through Unified Command?

  1. A room-and-contents fire in a single-family dwelling
  2. A vehicle collision on a state route within one district
  3. A wildfire crossing city, county, and federal land Correct answer.
  4. A dumpster fire behind a business in one response area

Explanation

Unified Command is used when several agencies or jurisdictions with overlapping authority share responsibility for an incident and jointly set objectives. A single-jurisdiction, single-agency incident is normally managed by one incident commander.

Question 18General (safety, health and wellness, incident management)

A Type 5 incident is best characterized as:

  1. A multi-operational-period event with a written action plan
  2. An event requiring a formal area command organization
  3. An initial attack managed locally under a single command Correct answer.
  4. A nationally significant event requiring a Type 1 team

Explanation

Type 5 is the least complex incident classification: a localized event handled by initial attack with local resources under a single command. Complexity increases through Types 4 to 1, with Type 1 requiring national-level resources and a full incident management team.

Question 19General (safety, health and wellness, incident management)

Within the Incident Command System, which section collects and evaluates incident information and prepares the Incident Action Plan?

  1. Finance/Administration Section
  2. Logistics Section
  3. Operations Section
  4. Planning Section Correct answer.

Explanation

The Planning Section gathers and evaluates situation and resource status information, tracks the incident, and prepares the Incident Action Plan for each operational period. The Operations Section translates those objectives into tactical direction of resources.

Question 20General (safety, health and wellness, incident management)

Which statement correctly describes the relationship between an emergency operations center and the incident command post?

  1. EOC staff direct tactical operations from the command post
  2. The incident commander must obtain EOC approval for each tactical assignment
  3. The EOC assumes command once it is activated for the incident
  4. The EOC coordinates support while the incident commander retains command authority Correct answer.

Explanation

An emergency operations center supports the incident by coordinating resources, policy, and interagency information, but it does not command the incident. Command authority remains with the incident commander or unified command at the command post.

Question 21Fire Department Communications

When transmitting on a fire department radio, which practice is recommended for Firefighter II personnel?

  1. Use plain language that any responding agency can understand Correct answer.
  2. Use department ten-codes for all critical messages
  3. Use signal codes to shorten transmission time
  4. Use informal slang that your own crew understands

Explanation

National incident management guidance and fire service communications standards call for clear text (plain language) so that responders from different agencies and jurisdictions can understand each other on shared channels. Codes and slang vary between departments and can cause dangerous misunderstandings.

Question 22Fire Department Communications

Which radio term tells the listener that the sender has finished transmitting and no reply is expected?

  1. Wilco
  2. Out Correct answer.
  3. Over
  4. Stand by

Explanation

"Out" signals the end of a transmission and of the exchange, meaning no answer is required. "Over" means the sender has finished and is inviting a reply, which is the opposite meaning.

Question 23Fire Department Communications

What should a firefighter do with a portable radio when entering a structure on a working fire?

  1. Turn it off inside the building to conserve battery
  2. Carry it and keep it turned on during interior operations Correct answer.
  3. Share it with a partner to reduce radio traffic
  4. Leave it in the apparatus cab so it stays charged

Explanation

Each member operating inside must have a means of radio communication with the incident commander or sector officer. The radio stays with the firefighter and stays on so that MAYDAY or emergency traffic can be transmitted immediately.

Question 24Fire Department Communications

Crews working inside a structure hear the repeated short blasts of apparatus audible warning devices that signal evacuation. What is the correct action?

  1. Ask on the radio whether the signal applies to your crew
  2. Finish the current task, then report at overhaul
  3. Exit the structure promptly and report to the accountability officer or supervisor Correct answer.
  4. Continue operating until water is applied to the fire

Explanation

The evacuation signal means all members are to leave the structure immediately, and crews must be accounted for after they exit. Waiting for confirmation or finishing a task delays the accountability report the incident commander needs to determine who may still be inside.

Question 25Fire Department Communications

When receiving a telephone report of an emergency, what information should the telecommunicator obtain first?

  1. The location of the emergency Correct answer.
  2. The name of the nearest hospital
  3. The caller's insurance information
  4. The suspected cause of the incident

Explanation

The location is the first essential element because responding units cannot be dispatched without it. Nature of the emergency, callback number, and caller name follow, but the address must be established before anything else.

Question 26Fire Department Communications

When should a crew normally perform a radio check on its portable radios?

  1. At the start of each shift or before operations begin Correct answer.
  2. Only after a radio has failed during an incident
  3. Only when the dispatcher requests one
  4. Once a month during scheduled training

Explanation

Radios are checked at the beginning of the duty period and before operations so that failures are found while there is still time to correct them. Discovering a dead battery or wrong channel during an interior attack is a serious safety problem.

Question 27Fire Department Communications

A firefighter is trapped by collapsed debris and needs rescue. Which transmission is appropriate?

  1. Emergency traffic
  2. A request for a second alarm
  3. A PAR request
  4. MAYDAY, giving name, location, and the nature of the problem Correct answer.

Explanation

A firefighter in distress declares a MAYDAY and follows it with the information rescuers need: who is calling, where the member is, and what the problem is. This distinct term alerts the incident commander that a member is in immediate danger.

Question 28Fire Department Communications

A crew chief sees conditions deteriorating rapidly and must interrupt radio traffic to warn all units, but no firefighter is in distress. Which transmission should be used?

  1. MAYDAY
  2. A PAR request
  3. A roll call
  4. Emergency traffic Correct answer.

Explanation

"Emergency traffic" is used to seize the channel for a critical safety message when no member is in distress. All other units hold traffic until the incident commander acknowledges and the emergency message is complete.

Question 29Fire Department Communications

The incident commander requests a PAR over the radio. What are crews being asked to do?

  1. Provide a preliminary assessment of the fire's origin
  2. Report the status and head count of their members Correct answer.
  3. Prepare a written report for the fire investigator
  4. Recommend additional resources for the fireground

Explanation

A personnel accountability report confirms that each crew's members are accounted for and is commonly requested after an evacuation, a MAYDAY, or a sudden change in conditions. Each crew answers with a simple status such as "all accounted for" or reports missing members.

Question 30Fire Department Communications

Your portable radio fails while your crew is operating inside a structure. What should you do?

  1. Switch to an unassigned channel and keep working there
  2. Exit with your crew and notify your supervisor so the radio can be replaced Correct answer.
  3. Borrow a radio from an outside crew without telling anyone
  4. Continue working and report the failure at overhaul

Explanation

Operating without communications puts the member and the crew at risk, because no MAYDAY or evacuation order can be received or sent. The crew leaves, and the failure is reported so the radio and any carried spare battery can be corrected.

Question 31Fire Department Communications

A company officer determines that an additional engine company is needed at the incident. How should the request be made?

  1. Through the incident commander to the dispatcher Correct answer.
  2. By telephone to the fire chief's office
  3. By mobile data terminal to a neighboring agency
  4. By radio directly to the nearest available engine company

Explanation

All requests for additional resources flow through the incident commander, who maintains the incident action plan and knows what is actually needed. The dispatcher then processes the request and tracks which units are committed.

Question 32Fire Department Communications

When a message is relayed by radio, what should the receiving station do to confirm it was received correctly?

  1. Repeat the message back to the sender for confirmation Correct answer.
  2. Wait several minutes before acting on the message
  3. Assume the message was heard if the channel was clear
  4. Switch channels and transmit the message to a third unit

Explanation

Repeating the message back lets the sender verify that the content arrived intact, which is essential for addresses, resource orders, and safety instructions. A quiet channel is not proof that the words were understood.

Question 33Fire Department Communications

Dispatch asks you to spell a street name that begins with the letter C. Which word should you use?

  1. Cat
  2. Canada
  3. Cesar
  4. Charlie Correct answer.

Explanation

A standardized phonetic alphabet is used so that letters that sound alike are never confused over the radio. In the internationally recognized alphabet, C is spoken as "Charlie."

Question 34Fire Department Communications

A "still alarm" refers to a fire that is reported:

  1. By an aircraft or other passing observer
  2. By telephone or in person rather than by a municipal alarm system Correct answer.
  3. Automatically by a municipal alarm system
  4. Only after a second alarm has been transmitted

Explanation

A still alarm describes a report made by telephone, by someone walking into the station, or by direct verbal notice, as opposed to activation of a municipal alarm system. The term describes how the alarm was received, not the size of the fire.

Question 35Fire Department Communications

A second alarm is transmitted for a working fire. What does this indicate?

  1. Additional companies are being dispatched according to the department's alarm assignment Correct answer.
  2. The fire has been brought under control
  3. A second, separate fire has been discovered
  4. The incident has been reclassified as a hazardous materials incident

Explanation

Alarm levels are prearranged assignments of companies; transmitting a second alarm adds the units listed in that assignment to the incident. The number of alarms reflects resource needs and does not by itself describe fire conditions or control status.

Question 36Fire Department Communications

While responding, a company receives a mobile data terminal update correcting the incident address. What should the officer do?

  1. Ignore it, because the original dispatch is authoritative
  2. Continue to the original address and resolve it on scene
  3. Acknowledge the corrected address with dispatch and proceed to that location Correct answer.
  4. Ask a neighboring department to handle the call instead

Explanation

Updated information from the dispatch center supersedes the original assignment, but it must be acknowledged so all responding units work from the same address. Continuing to the first address can put units in the wrong place and split the response.

Question 37Fire Department Communications

NFPA 1221 establishes 90th-percentile time objectives for public emergency communications. What is the alarm processing time objective applied at the 90th percentile?

  1. 30 seconds
  2. 60 seconds Correct answer.
  3. 240 seconds
  4. 120 seconds

Explanation

Alarm processing, from call receipt to the dispatch of the alarm, carries a 90th-percentile objective of 60 seconds, with a longer allowance at the 99th percentile. The shorter benchmark is used because most calls are straightforward and only a minority require extra call-processing time.

Question 38Fire Department Communications

Why does a repeated (repeater-based) radio system provide better coverage for portable radios than direct unit-to-unit communication?

  1. It converts voice traffic into text messages for clarity
  2. A fixed receiver picks up the portable's signal and retransmits it at higher power Correct answer.
  3. It boosts the transmit power of each portable at its own antenna
  4. It connects all field radios to the public telephone network

Explanation

A portable transmits at low power, so a repeater located on a high site hears the weak signal and rebroadcasts it at higher power over a wide area. This lets handhelds reach units and dispatchers far beyond their own direct range.

Question 39Fire Department Communications

A MAYDAY is transmitted on the fireground channel. What should other units on that channel do?

  1. Re-transmit the MAYDAY to make sure it was heard
  2. Continue routine traffic so command stays informed of conditions
  3. Maintain radio silence except for traffic essential to the rescue Correct answer.
  4. Switch channels and continue their assignments without reporting

Explanation

Once a MAYDAY is declared, the channel belongs to the member in distress and the rescue effort until command releases it. Other units keep the channel clear so the distress message and rescue instructions are not stepped on.

Question 40Fire Department Communications

At a multiagency incident, what is the purpose of assigning an interoperability channel?

  1. To let each agency use its own codes without interference
  2. To give responding agencies from different jurisdictions a shared frequency for direct communication Correct answer.
  3. To prevent the public from monitoring tactical traffic
  4. To reduce the number of dispatchers needed for the incident

Explanation

An interoperability channel is programmed into multiple agencies' radios so commanders and crews from different departments can talk directly to one another. Without a shared channel, requests must be relayed between dispatch centers and coordination breaks down.

Question 41Fireground Operations

What is the primary purpose of vertical ventilation at a structure fire?

  1. Creating an escape route for trapped occupants
  2. Pushing fresh air into the fire compartment
  3. Cooling the roof deck with a fog stream
  4. Releasing heat and smoke from the building Correct answer.

Explanation

Vertical ventilation opens the structure at the highest point above the fire so rising heated gases and smoke escape. This improves interior visibility and reduces the buildup of unburned products of combustion. It does not by itself cool the roof or create an egress route.

Question 42Fireground Operations

Where should the tip of a ground ladder be placed when it will be used to rescue a person from a window?

  1. Two rungs below the windowsill
  2. Level with the windowsill Correct answer.
  3. Three to five rungs above the windowsill
  4. At the top of the window frame

Explanation

For a window rescue the tip is placed level with the sill so a firefighter on the ladder can reach in and assist the occupant out. Extending the tip three to five rungs above the opening is the standard for roof access, not for removing a victim.

Question 43Fireground Operations

A firefighter inside a burning building becomes disoriented and cannot find an exit. When should the firefighter transmit a MAYDAY?

  1. After notifying the company officer face to face
  2. After attempting to find the exit for several minutes
  3. As soon as the loss of orientation is recognized Correct answer.
  4. Once the low-air alarm activates

Explanation

A MAYDAY is declared the moment the emergency is recognized, because every minute of delay consumes the firefighter's air supply and narrows the window for rescuers. Early declaration lets command redirect resources while the firefighter still has time and air to act.

Question 44Fireground Operations

How do individual sprinkler heads in a typical wet-pipe system activate?

  1. Heads are opened at the riser by the fire department
  2. Heads open in sequence from the farthest to the nearest
  3. All heads open at once when the system detects smoke
  4. Each head opens individually when its element is heated Correct answer.

Explanation

Sprinkler heads are heat-actuated devices that operate one at a time as the temperature at each head reaches its rating. This concentrates water on the fire area and limits water damage elsewhere in the building.

Question 45Fireground Operations

What is the purpose of deploying salvage covers during fireground operations?

  1. Marking hazardous areas for the safety officer
  2. Protecting undamaged property from water and debris Correct answer.
  3. Directing hose streams toward the fire
  4. Catching falling glass and building materials

Explanation

Salvage covers shield furnishings and contents from water runoff, smoke, and falling debris so losses beyond the fire area are reduced. They are a property-conservation tool and are not used to support firefighting or safety functions.

Question 46Fireground Operations

What is the main objective of overhaul?

  1. Removing smoke with positive pressure fans
  2. Documenting the area of origin for investigators
  3. Restoring utilities to the building
  4. Finding and extinguishing hidden fire Correct answer.

Explanation

Overhaul systematically opens concealed spaces and checks for remaining heat so the fire cannot rekindle after crews leave. Ventilation and origin work may occur at the same time, but they are separate functions with different objectives.

Question 47Fireground Operations

Which practice should a firefighter follow before forcing entry through a door?

  1. Discharge a hose stream through the opening first
  2. Break the glass nearest the lock
  3. Try the door to see if it is already unlocked Correct answer.
  4. Cut the hinge pins to remove the door

Explanation

Doors on firegrounds are often unlocked or unlatched, so the first action is to try the door. Forcible entry tools are used only after that simple check fails, which avoids unnecessary damage and delay.

Question 48Fireground Operations

A fire involving gasoline spilled on a garage floor is classified as which class of fire?

  1. Class B Correct answer.
  2. Class A
  3. Class C
  4. Class D

Explanation

Class B fires involve flammable and combustible liquids such as gasoline, oil, and solvents. Class A covers ordinary combustibles, Class C covers energized electrical equipment, and Class D covers combustible metals.

Question 49Fireground Operations

A transitional attack is best described as:

  1. Short exterior cooling of fire gases before entry Correct answer.
  2. An attack made without a charged hoseline
  3. An attack started at the rear and finished at the front
  4. A prolonged exterior attack to protect exposures only

Explanation

In a transitional attack, crews briefly apply water from outside through a window or doorway to cool the upper layer and knock down visible fire, then move inside to finish extinguishment. The exterior stream is a short transition, not the whole operation.

Question 50Fireground Operations

In a high-rise fire, firefighters should connect their attack line to which standpipe outlet?

  1. The outlet at the ground floor riser
  2. The outlet one floor below the fire floor Correct answer.
  3. The outlet two floors above the fire floor
  4. The outlet on the fire floor

Explanation

Hose is connected one floor below the fire so crews can stretch up the stairs and approach the fire floor from a protected position outside the fire area. The system must be supplied at the fire department connection before the line is charged.
