Question 1Reading Comprehension

A fire department notice reads: 'All personnel must report to the training yard by 0700 hours unless excused by a shift supervisor.' According to the notice, what happens at 0700 hours?

  1. Personnel report to the training yard Correct answer.
  2. New recruits take a written test
  3. The shift ends for the day
  4. Supervisors inspect the equipment

Explanation

The notice states that personnel must report to the training yard by 0700 hours. The time is tied directly to the reporting requirement.

Question 2Reading Comprehension

Read this sentence: 'Because the hydrant valve was corroded, the crew could not open it during the drill.' Why could the crew not open the valve?

  1. The crew lacked a wrench
  2. The drill was cancelled
  3. The valve was the wrong size
  4. The valve was corroded Correct answer.

Explanation

The word 'because' signals cause and effect; the stated cause is that the valve was corroded. That corrosion is what prevented the crew from opening it.

Question 3Reading Comprehension

A memo states: 'Turnout gear must be inspected after every use. Damaged gear must be tagged and removed from service immediately.' What must happen to damaged gear?

  1. It must be used only in drills
  2. It must be tagged and removed Correct answer.
  3. It must be repaired on the spot
  4. It must be stored in a locker

Explanation

The memo gives a direct instruction for damaged gear: tag it and remove it from service immediately. That is the required action.

Question 4Reading Comprehension

An incident report says: 'Smoke was visible from three blocks away when Engine 2 arrived.' What does this sentence tell you about the smoke?

  1. It was coming from Engine 2
  2. It had already cleared
  3. It was thick enough to see from a distance Correct answer.
  4. It was confined to one room

Explanation

Being visible from three blocks away indicates the smoke could be seen from a long distance, implying it was substantial. The sentence reports visibility, not its source or spread.

Question 5Reading Comprehension

A sign at the station reads: 'No parking in front of the bay doors at any time.' What does the sign prohibit?

  1. Parking in front of the bay doors Correct answer.
  2. Driving past the station
  3. Parking anywhere on the property
  4. Entering the bay area on foot

Explanation

The sign specifically bans parking in front of the bay doors at all times. The restriction is limited to that location.

Question 6Reading Comprehension

A paragraph begins: 'Rapid intervention crews serve one primary purpose: rescuing firefighters who become trapped or disoriented inside a structure.' What is the paragraph most likely about?

  1. The role of rapid intervention crews Correct answer.
  2. How fires start in structures
  3. The history of fire departments
  4. How to inspect breathing apparatus

Explanation

The opening sentence names rapid intervention crews and states their purpose, which signals the paragraph's topic. The remaining text would logically develop that role.

Question 7Reading Comprehension

Read this sentence: 'The captain radioed dispatch, then ordered the crew to stretch a line to the second floor.' What did the captain do first?

  1. Stretched the hose line
  2. Radioed dispatch Correct answer.
  3. Entered the building
  4. Ordered the crew upstairs

Explanation

The word 'then' shows the order of events: radioing dispatch came before ordering the crew to stretch a line. Sequence words like 'then' mark what happened later.

Question 8Reading Comprehension

A safety bulletin states: 'Never enter a confined space without a standby attendant posted outside.' What does the bulletin require?

  1. A standby attendant outside the space Correct answer.
  2. Two crews inside the space
  3. A radio check every minute
  4. A permit signed by a chief

Explanation

The bulletin requires a standby attendant to be posted outside before anyone enters a confined space. That is the explicit condition stated.

Question 9Reading Comprehension

Read this passage: 'Ground ladders should be checked before each shift. Crews look for cracked beams, damaged rungs, and worn halyards. Any ladder found defective is removed from service until repaired.' What is the main idea of the passage?

  1. Halyards wear out faster than beams
  2. Ladder inspection and removal of defects Correct answer.
  3. Ladders are expensive to replace
  4. Ground ladders are used on every call

Explanation

The passage describes when ladders are checked, what defects are sought, and what happens to defective ladders. Together these details support the main idea of inspection and removal of defects.

Question 10Reading Comprehension

A report states: 'Although the flames were extinguished within ten minutes, overhaul continued for two hours.' What does the sentence imply about overhaul?

  1. It began before the flames were out
  2. It took much longer than fire suppression Correct answer.
  3. It lasted only ten minutes
  4. It was unnecessary after the fire

Explanation

The contrast word 'although' sets the ten-minute extinguishment against a two-hour overhaul, implying overhaul took far longer. The sentence compares the durations of the two phases.

Question 11Reading Comprehension

Read this sentence: 'The smoke detector chirped intermittently, a sound the homeowner had ignored for weeks.' What can you infer about the homeowner?

  1. The homeowner did not act on the warning Correct answer.
  2. The homeowner was away for weeks
  3. The homeowner installed a new alarm
  4. The homeowner replaced the detector

Explanation

Ignoring the chirp for weeks suggests the homeowner did not respond to the warning. The word 'ignored' directly supports this inference.

Question 12Reading Comprehension

A procedures manual says: 'Ventilation should be coordinated with the attack crew so that heat and smoke are released ahead of the advancing line.' Why should ventilation be coordinated with the attack crew?

  1. To reduce the number of responders
  2. To test the building's alarm system
  3. To keep the apparatus bay clear
  4. To release heat and smoke ahead of the line Correct answer.

Explanation

The manual states the purpose directly: releasing heat and smoke ahead of the advancing line. Coordination serves the attack crew's progress.

Question 13Reading Comprehension

Read this passage: 'The first-arriving officer assumed command and completed a size-up. She noted heavy smoke from the rear, a downed power line, and occupants at a second-floor window. She then assigned tasks to incoming units.' What did the officer do immediately after completing the size-up?

  1. Assigned tasks to incoming units Correct answer.
  2. Called the power company
  3. Entered the building alone
  4. Rescued the occupants

Explanation

The passage lists the size-up, then says 'She then assigned tasks to incoming units.' The word 'then' marks the next action in sequence.

Question 14Reading Comprehension

A training handout states: 'SCBA cylinders must be refilled only by trained personnel using approved compressors. Cylinders filled from unapproved sources may contain contaminated air.' What is the risk of using an unapproved source?

  1. The cylinder may be overfilled
  2. The air may be contaminated Correct answer.
  3. The compressor may overheat
  4. The mask may fog

Explanation

The handout explicitly warns that cylinders filled from unapproved sources may contain contaminated air. That is the stated hazard.

Question 15Reading Comprehension

Read this sentence: 'The fire spread quickly through the attic because the balloon-frame construction created a continuous void from the basement to the roof.' What caused the rapid spread?

  1. A delayed alarm notification
  2. A continuous void in the framing Correct answer.
  3. A lack of water supply
  4. Open windows on the first floor

Explanation

The sentence attributes the rapid spread to a continuous void created by balloon-frame construction. The 'because' clause names the cause.

Question 16Reading Comprehension

A policy reads: 'Personnel may exchange shifts provided the exchange is approved in writing by both company officers at least 48 hours in advance.' Which condition must be met for a shift exchange?

  1. Written approval from both officers in advance Correct answer.
  2. Verbal approval from one officer
  3. Approval from the union steward
  4. Approval on the day of the shift

Explanation

The policy requires written approval from both company officers at least 48 hours ahead. All parts of that condition must be satisfied.

Question 17Reading Comprehension

Read this passage: 'Forcible entry damages the building, so it should be used only when normal means of access fail. Before forcing a door, try the knob, check for a lockbox, and look for an open window.' What is the author's main point about forcible entry?

  1. It should be a last resort Correct answer.
  2. It requires no tools
  3. It is always prohibited
  4. It should be the first method tried

Explanation

The passage advises using forcible entry only when normal access fails and lists gentler methods to try first. This supports the idea that it is a last resort.

Question 18Reading Comprehension

A sentence reads: 'Unlike a Class A fire, which involves ordinary combustibles, a Class B fire involves flammable liquids.' What is the difference the sentence draws?

  1. Class A fires burn outdoors
  2. The type of fuel involved Correct answer.
  3. The size of the fire
  4. The time of day the fire starts

Explanation

The sentence contrasts the two classes by their fuel: ordinary combustibles versus flammable liquids. The distinction is about what is burning.

Question 19Reading Comprehension

Read this passage: 'The pump operator must monitor discharge pressure closely. If pressure drops below the nozzle requirement, the line loses reach and the crew inside is endangered. Adjustments should be made smoothly to avoid water hammer.' What is the consequence of pressure dropping below the nozzle requirement?

  1. The pump shuts down automatically
  2. The crew gains better reach
  3. The line loses reach and the crew is endangered Correct answer.
  4. The hose bursts immediately

Explanation

The passage states that if pressure falls below the nozzle requirement, the line loses reach and the interior crew is endangered. That is the described consequence.

Question 20Reading Comprehension

A notice reads: 'Due to scheduled maintenance, the apparatus floor will be closed Tuesday from 0800 to 1200. All gear normally stored there must be moved to the rear bay by Monday evening.' By when must the gear be moved?

  1. Wednesday morning
  2. Monday evening Correct answer.
  3. Tuesday at 0800
  4. Tuesday at 1200

Explanation

The notice sets Monday evening as the deadline for moving the gear. Tuesday's times refer to the floor closure, not the gear deadline.

Question 21Reading Comprehension

Read this sentence: 'The investigators determined that the fire originated in the kitchen, but the exact ignition source remained unclear.' What do the investigators know for certain?

  1. The exact ignition source
  2. That the fire was intentional
  3. That the stove caused the fire
  4. Where the fire started Correct answer.

Explanation

The sentence states the origin was determined to be the kitchen, while the ignition source remained unclear. The location is known; the cause is not.

Question 22Reading Comprehension

A manual states: 'When two crews work on the same hoseline, the backup crew should equal the advance crew in number so that the line can be moved without fatigue.' Why should the backup crew equal the advance crew?

  1. To reduce the number of officers
  2. To speed up the pump connection
  3. To allow the line to be moved without fatigue Correct answer.
  4. To satisfy inspection rules

Explanation

The manual gives the reason in the same sentence: so the line can be moved without fatigue. The stated purpose follows the words 'so that.'

Question 23Reading Comprehension

Read this passage: 'A mayday should be called as soon as a firefighter becomes lost, trapped, or low on air. Waiting until the situation becomes critical delays rescue and reduces the chances of a successful outcome. The call should include location, unit, and the nature of the problem.' What is the author's primary message?

  1. Maydays should be called early and include key details Correct answer.
  2. Mayday calls should be brief and omit location
  3. Maydays are rarely necessary
  4. Maydays should be reserved for injuries

Explanation

The passage urges calling a mayday as soon as trouble arises and lists the details the call should contain. Both points support the message of early, complete mayday calls.

Question 24Reading Comprehension

An after-action report notes: 'The crew advanced the line through the front door, but the fire had already extended into the attic. The attack was redirected to the second floor, yet the fire continued to spread above them.' What best explains why the attack was redirected?

  1. The crew ran out of water
  2. The attic was empty
  3. The fire had extended beyond the initial attack point Correct answer.
  4. The front door was locked

Explanation

The report indicates the fire had extended into the attic, so the attack was redirected to the second floor. The redirection follows from the fire's spread beyond the original point.

Question 25Reading Comprehension

Read this passage: 'Two identical-appearing structures were involved. In the first, firefighters found a lightweight truss roof that failed within minutes of flame contact. In the second, a conventional roof held for over thirty minutes. The lesson is that roof construction, not outward appearance, dictates how long a roof can be safely worked on.' What conclusion does the author draw?

  1. Outward appearance predicts roof failure
  2. Lightweight trusses are safer than conventional roofs
  3. Roof construction determines safe working time Correct answer.
  4. All roofs fail within minutes

Explanation

The author contrasts two roofs that looked alike but performed differently, then states the lesson: construction, not appearance, dictates safe working time. The contrast supports that conclusion.

Question 26Reading Comprehension

A department memo reads: 'All personnel must complete the annual fit test before donning respiratory protection in an IDLH atmosphere.' According to the memo, when must the fit test be completed?

  1. After the first year of employment has ended
  2. Before any use of respiratory protection in an IDLH atmosphere Correct answer.
  3. Whenever a supervisor requests it during an incident
  4. Only after a respiratory injury has occurred

Explanation

The memo makes the fit test a precondition: it must be done annually and before a member wears respiratory protection in an immediately dangerous to life or health atmosphere. The timing is tied to use of the equipment, not to a supervisor's request or to a later anniversary.

Question 27Reading Comprehension

Read this sentence: 'The nozzle operator opened the line slowly, allowing water to reach the fire without disrupting the thermal layer overhead.' What is the stated reason for opening the line slowly?

  1. To allow the backup crew time to arrive
  2. To avoid disturbing the hot layer above the fire Correct answer.
  3. To signal the pump operator to increase pressure
  4. To conserve the apparatus water supply

Explanation

The sentence links the slow opening directly to letting water reach the fire without disrupting the thermal layer overhead. That clause states the purpose, so the answer must reflect protection of the hot gas layer rather than supply or staffing concerns.

Question 28Reading Comprehension

A paragraph states: 'Apparatus must be positioned so that the pump intake is accessible and the truck does not block the arrival of later-arriving units. When a hydrant is used, the driver should stop short of it rather than past it.' What is the practical effect of stopping short of the hydrant?

  1. It eliminates the need for a separate water supply
  2. It guarantees the hydrant will not be struck by traffic
  3. It allows the truck to leave before the fire is out
  4. It keeps the hose connection within reach of the intake Correct answer.

Explanation

Stopping short leaves the hydrant between the truck and the direction of travel, so the intake can be reached with a short section of hard suction. The passage frames positioning around intake access and not blocking later units, not around traffic protection or water-supply elimination.

Question 29Reading Comprehension

Read this passage: 'A smoke alarm sounded in a two-story dwelling. The first crew found light smoke on the second floor and no visible fire. The officer ordered a charged line advanced to the second floor before the crew began searching for the source.' What does the passage suggest about the officer's priorities?

  1. Searching was delayed until a water source was confirmed
  2. The crew treated the alarm as a false activation
  3. The second floor was declared safe before entry
  4. A charged line was placed before the source was located Correct answer.

Explanation

The order of events in the passage is the key: the line was advanced before the crew began searching for the source. That sequence shows the officer wanted extinguishing capability in place before the search proceeded, not that the alarm was dismissed.

Question 30Reading Comprehension

A report states: 'The building had been renovated several times. Original heavy timber remained in the walls, but the roof had been replaced with lightweight engineered trusses. Firefighters should expect the roof to fail earlier than the walls would suggest.' Which conclusion is best supported by the report?

  1. The walls will fail before the roof under fire conditions
  2. Repeated renovation always improves structural fire resistance
  3. Lightweight trusses may fail sooner than the older wall construction Correct answer.
  4. The age of the walls reliably predicts roof performance

Explanation

The report contrasts original heavy timber walls with a roof of lightweight engineered trusses and warns that the roof will fail earlier than the walls would suggest. The supported conclusion is therefore that the newer roof assembly may fail sooner than the older walls.

Question 31Verbal Reasoning

A firefighter reads this order: "All recruits must stow their gear before the drill begins." Which statement must be true?

  1. Every recruit stows gear before the drill starts. Correct answer.
  2. Some recruits stow gear after the drill starts.
  3. Only senior recruits stow gear early.
  4. Recruits may stow gear during the drill.

Explanation

The word "all" makes the requirement universal: every recruit is covered, and the timing is fixed as before the drill begins. Any statement that allows stowing later contradicts the order.

Question 32Verbal Reasoning

Read the passage: "The alarm sounded at 03:12. Engine 4 arrived at the scene at 03:19." How long did Engine 4 take to arrive after the alarm?

  1. Six minutes
  2. Twelve minutes
  3. Nine minutes
  4. Seven minutes Correct answer.

Explanation

Elapsed time is found by subtracting the earlier time from the later one: 03:19 minus 03:12 equals 7 minutes.

Question 33Verbal Reasoning

Which word is closest in meaning to "hazard" as used in a safety briefing?

  1. Shortcut
  2. Danger Correct answer.
  3. Routine
  4. Delay

Explanation

In safety contexts a hazard is a source of potential harm, so danger is the closest synonym. The other words describe scheduling or method rather than risk.

Question 34Verbal Reasoning

Read the passage: "The smoke detector chirped, but the battery was new." What does "but" signal here?

  1. An additional supporting reason
  2. A cause-and-effect link
  3. A conclusion drawn from evidence
  4. A contrast between expectation and fact Correct answer.

Explanation

The conjunction "but" marks contrast: a new battery would normally prevent chirping, yet the chirping occurred. It does not signal cause, addition, or conclusion.

Question 35Verbal Reasoning

A memo states: "No apparatus may leave the bay without a completed checklist." Which situation complies with the memo?

  1. A truck leaves before the checklist is reviewed.
  2. A truck leaves while the checklist is being printed.
  3. A truck leaves with the checklist left on a desk.
  4. A truck leaves after the driver signs the checklist. Correct answer.

Explanation

The memo requires a completed checklist before departure, so only the case where the checklist is finished and signed before leaving complies. The others all involve leaving without completion.

Question 36Verbal Reasoning

Which sentence uses "station" correctly as a verb?

  1. The station was quiet overnight.
  2. Crews station themselves near the exit. Correct answer.
  3. The station chief called roll.
  4. She bought a station map.

Explanation

As a verb, "station" means to place or position someone. Only the sentence describing crews positioning themselves uses it that way.

Question 37Verbal Reasoning

Passage: "The hose failed during the test. Inspectors later found a small cut near the coupling." Which claim is best supported?

  1. The coupling was replaced last week.
  2. The hose was brand new.
  3. The cut likely contributed to the failure. Correct answer.
  4. The test was conducted incorrectly.

Explanation

The passage links a cut near the coupling to a failure at the same location, so the reasonable supported inference is that the cut likely contributed. The other claims are never stated.

Question 38Verbal Reasoning

Choose the word that best completes the sentence: "The crew worked ___ to contain the fire before it spread."

  1. swiftness
  2. swiftly Correct answer.
  3. swift
  4. swiftest

Explanation

The blank modifies the verb "worked," so an adverb is required; "swiftly" is the adverb form. The others are adjective or noun forms.

Question 39Verbal Reasoning

"The chief's instructions were ambiguous." What does "ambiguous" most nearly mean?

  1. Open to more than one interpretation Correct answer.
  2. Repeated often
  3. Written in code
  4. Strictly enforced

Explanation

Ambiguous describes something that can be understood in more than one way. Enforcement, coding, and repetition are unrelated to the meaning.

Question 40Verbal Reasoning

A report says: "If the hydrant pressure drops below 40 psi, the pump operator must switch to the secondary line." Pressure reads 35 psi. What follows?

  1. The operator must shut down the pump.
  2. The operator may keep the primary line.
  3. The operator must call for a new hydrant.
  4. The operator must switch to the secondary line. Correct answer.

Explanation

This is a conditional rule: when the condition (pressure below 40 psi) is met, the required action is to switch lines. Since 35 is below 40, the action is required.

Question 41Verbal Reasoning

Which pair of words are antonyms?

  1. Inspect and examine
  2. Flammable and combustible
  3. Ignite and extinguish Correct answer.
  4. Alert and vigilant

Explanation

Antonyms are words with opposite meanings; to ignite is to start a fire while to extinguish is to put one out. The other pairs are near-synonyms.

Question 42Verbal Reasoning

Passage: "Although the drill lasted only ten minutes, the recruits practiced three evolutions." What does "although" emphasize?

  1. The evolutions were unnecessary
  2. The recruits were inexperienced
  3. The drill was poorly organized
  4. The short time contrasts with the amount accomplished Correct answer.

Explanation

"Although" introduces a contrast, here between the brief duration and the number of evolutions completed. It does not comment on organization, necessity, or experience.

Question 43Verbal Reasoning

Which sentence is written in the active voice?

  1. Testing of the alarm was done.
  2. The captain tested the alarm. Correct answer.
  3. The alarm had been tested.
  4. The alarm was tested by the captain.

Explanation

In active voice the subject performs the action; "the captain tested the alarm" fits that pattern. The other sentences put the alarm first as the receiver of the action.

Question 44Verbal Reasoning

A bulletin reads: "Unless the wind shifts, crews will hold the current line." Which statement is consistent?

  1. If the wind does not shift, crews advance.
  2. If the wind does not shift, crews hold the line. Correct answer.
  3. The wind has already shifted.
  4. Crews will retreat regardless of wind.

Explanation

"Unless X, Y" means "if not X, then Y." So if the wind does not shift, the crews hold the line. The other options contradict or add facts not given.

Question 45Verbal Reasoning

Passage: "Three crews responded. Crew A arrived first, Crew B second, and Crew C third. Crew B carried the ladder." Which crew arrived immediately before the ladder crew?

  1. Crew C
  2. Crew A Correct answer.
  3. Crew B
  4. Cannot be determined

Explanation

Crew B is the ladder crew and arrived second, so the crew immediately before it is the first-arriving crew, Crew A. The order is given explicitly.

Question 46Verbal Reasoning

Which word best completes the analogy? "Nozzle is to hose as ___ is to ladder."

  1. Water
  2. Helmet
  3. Rung Correct answer.
  4. Alarm

Explanation

A nozzle is a component attached to a hose, so the matching relationship is a component of a ladder, which is a rung. The other words are not ladder parts.

Question 47Verbal Reasoning

Passage: "The investigator noted that the door was unlocked and the windows were intact. She concluded the entry was made through the door." Which assumption does the conclusion rely on?

  1. Entry occurred through some opening in the structure. Correct answer.
  2. The windows were recently replaced.
  3. The door had been forced open.
  4. The building was unoccupied.

Explanation

Reasoning from intact windows and an unlocked door to door entry assumes the entry used one of these openings. The other statements are neither stated nor needed.

Question 48Verbal Reasoning

A policy states: "Only personnel who have completed confined-space training may enter a confined space, and entry requires a standby attendant." A trained firefighter enters alone. Which rule is broken?

  1. Both requirements are met
  2. The training requirement
  3. No rule applies to firefighters
  4. The standby attendant requirement Correct answer.

Explanation

The firefighter satisfies the training condition but enters without the required standby attendant, so only the attendant rule is broken. The training rule is already met.

Question 49Verbal Reasoning

Passage: "Response times improved after the new dispatch software was installed, but staffing also increased that same month." What is the main point?

  1. The software caused the improvement.
  2. Staffing increases never help response times.
  3. The improvement cannot be credited solely to the software. Correct answer.
  4. The software should be removed.

Explanation

Because two changes occurred at once, the passage cautions against attributing the improvement to only one of them. It does not assert causation by the software or make recommendations.

Question 50Verbal Reasoning

Read the passage: "The captain praised the engineer for the rapid pump setup. The nozzle team, however, was criticized for leaving a coupling loose." Which statement is best supported by the passage?

  1. The captain was unhappy with the pump setup but pleased with the nozzle team.
  2. The captain was pleased with the pump setup but not with the nozzle team's work. Correct answer.
  3. The captain criticized the engineer and the nozzle team equally.
  4. The nozzle team received praise for tightening the coupling.

Explanation

The passage pairs praise for the engineer's pump setup with criticism of the nozzle team over a loose coupling, so the captain's reaction was mixed in that specific way. The word "however" signals the contrast between the two evaluations.
