Firefighter Exam Flashcards

Q: What do these firefighter flashcards cover?

They review Firefighter I & II written-test concepts such as fire behavior, PPE and SCBA, building construction, tools, ladders, ventilation, hose operations, search and rescue, communications, ropes, and hazmat awareness.

Q: Are firefighter flashcards enough to pass certification?

No. Flashcards help with terminology and decision points, but firefighter certification also requires approved hands-on training, practical-skill performance, and state or local testing requirements.

Q: Should I study state-specific firefighter rules?

Yes. Firefighter I & II concepts are broadly similar, but eligibility, retakes, forms, fees, and practical-skill requirements are controlled by the certifying agency in your jurisdiction.

Question 1

Fire tetrahedron

Accepted Answer

Fire needs fuel, heat, oxygen, and an uninhibited chemical chain reaction. Removing any one side stops combustion.

Question 2

Fire triangle vs tetrahedron

Accepted Answer

The triangle names fuel, heat, and oxygen. The tetrahedron adds the chemical chain reaction, which explains why some agents interrupt flame chemistry.

Question 3

Conduction

Accepted Answer

Heat moves through a solid material or between touching objects. A hot pipe, beam, or door hardware can extend fire without visible flame.

Question 4

Convection

Accepted Answer

Heat moves through hot gases or liquids. In buildings, convection carries smoke and heat upward through stairs, shafts, voids, and open paths.

Question 5

Radiation

Accepted Answer

Heat travels by electromagnetic waves without direct contact. Radiant heat can ignite nearby exposures and injure firefighters before flame reaches them.

Question 6

Thermal layering

Accepted Answer

Hot smoke and gases collect high while cooler air remains lower. Staying low can preserve survivable space, but disturbed layers can worsen conditions quickly.

Question 7

Rollover warning

Accepted Answer

Rollover is ignition of unburned gases in the upper layer. It signals dangerous overhead heat and possible progression toward flashover.

Question 8

Flashover

Accepted Answer

Flashover is the rapid transition when exposed combustibles in a compartment ignite nearly together. It is usually unsurvivable without immediate protection and withdrawal.

Question 9

Backdraft

Accepted Answer

Backdraft is sudden ignition of fuel-rich smoke after oxygen enters a ventilation-limited space. Pressurized dark smoke, pulsing smoke, and smoke-stained windows are warning signs.

Question 10

Flow path

Accepted Answer

A flow path is the route heat and smoke take from the fire area toward an exhaust opening. Door and ventilation control help keep that path from endangering crews.

Question 11

Fuel-limited fire

Accepted Answer

A fuel-limited fire has enough oxygen, so available fuel controls growth. Removing fuel or cooling the fuel package limits the fire.

Question 12

Ventilation-limited fire

Accepted Answer

A ventilation-limited fire is oxygen-starved. Opening doors or windows before water is ready can intensify fire conditions.

Question 13

Class A fire

Accepted Answer

Class A fires involve ordinary combustibles such as wood, paper, cloth, and many plastics. Cooling and soaking are usually important to prevent rekindle.

Question 14

Class B fire

Accepted Answer

Class B fires involve flammable or combustible liquids and gases. Suppression often requires vapor control, foam, shutoff, or nonconductive agents depending on the fuel.

Question 15

Class C fire

Accepted Answer

Class C means energized electrical equipment is involved. Once power is secured, classify the remaining fire by the burning material.

Question 16

Class D and K fires

Accepted Answer

Class D involves combustible metals; Class K involves cooking oils and fats. Both require agents matched to the hazard, not routine water application.

Question 17

PASS extinguisher method

Accepted Answer

Pull the pin, Aim at the base, Squeeze the handle, and Sweep side to side. Keep an exit behind you and leave if the fire grows.

Question 18

Class A vs Class B foam

Accepted Answer

Class A foam helps water penetrate ordinary combustibles. Class B foam blankets flammable liquids to separate fuel vapors from oxygen.

Question 19

Alcohol-resistant foam

Accepted Answer

Polar solvents such as alcohol can break down standard foam. Alcohol-resistant foam forms a protective layer so the blanket can survive.

Question 20

Direct fire attack

Accepted Answer

A direct attack applies water to the burning fuel. It is most useful when the seat of the fire is reachable and conditions permit.

Question 21

Indirect fire attack

Accepted Answer

An indirect attack applies water into a heated compartment to make steam and cool gases when firefighters cannot safely make direct access.

Question 22

Transitional attack

Accepted Answer

A transitional attack uses exterior water briefly to cool the fire area before interior advancement. It must be coordinated so crews do not create uncontrolled flow paths.

Question 23

Overhaul goal

Accepted Answer

Overhaul finds and extinguishes hidden fire after knockdown. Use hand tools, TIC checks, and careful opening of voids while preserving evidence when needed.

Question 24

Nozzle pattern choice

Accepted Answer

Straight or solid streams reach farther and penetrate better. Fog patterns can protect, ventilate, or cool gases but may disturb heat layers if misused.

Question 25

Friction loss

Accepted Answer

Friction loss is pressure lost as water moves through hose, appliances, and fittings. Longer hose, higher flow, and smaller diameter increase loss.

Question 26

Hydrant forward lay

Accepted Answer

In a forward lay, hose is laid from the water source toward the fire. It supports engine placement near the scene while establishing supply.

Question 27

Drafting

Accepted Answer

Drafting pulls water from a static source such as a pond or portable tank. Airtight connections and proper priming are essential.

Question 28

Water hammer

Accepted Answer

Water hammer is a pressure surge from closing valves or nozzles too quickly. Operate valves smoothly to protect hose, pumps, and appliances.

Question 29

PPE inspection mindset

Accepted Answer

Inspect PPE for contamination, damage, fit, and missing components before use. Defective or contaminated gear can fail when conditions become dangerous.

Question 30

SCBA low-air alarm

Accepted Answer

A low-air alarm means leave the hazardous atmosphere, notify the team or command, and manage air for exit. It is not a signal to keep working.

Question 31

Air management rule

Accepted Answer

Track air by time, work rate, pressure checks, and exit distance. Plan to leave before the alarm so reserve air remains for problems.

Question 32

PASS device

Accepted Answer

A PASS device alerts others when a firefighter is motionless or in distress. Activate it manually during a Mayday if you need rescue.

Question 33

Post-fire decontamination

Accepted Answer

Gross decon, gear cleaning, and hygiene reduce exposure to products of combustion. Treat contaminated PPE as a health hazard, not just dirty equipment.

Question 34

Mayday LUNAR

Accepted Answer

LUNAR reports Location, Unit, Name, Assignment or Air, and Resources needed. A concise Mayday gives command usable rescue information.

Question 35

CAN report

Accepted Answer

CAN means Conditions, Actions, and Needs. It keeps radio traffic brief while telling command what is happening, what you are doing, and what you need.

Question 36

Unity of command

Accepted Answer

Unity of command means each person reports to one supervisor. It reduces conflicting orders and keeps accountability clear.

Question 37

Personnel accountability

Accepted Answer

Accountability tracks who is operating, where they are assigned, and when they enter or exit hazards. It is critical before a rescue or evacuation order.

Question 38

Type I construction

Accepted Answer

Type I is fire-resistive construction with protected structural members. It can still fail under severe fire, impact, or prolonged heat exposure.

Question 39

Type III construction

Accepted Answer

Type III usually has noncombustible exterior walls with combustible interior members. Hidden fire can travel through voids and cocklofts.

Question 40

Type IV construction

Accepted Answer

Type IV is heavy timber. Large members may char and retain strength for a time, but contents, connections, and long-duration fires still create hazards.

Question 41

Type V construction

Accepted Answer

Type V is wood-frame construction. Combustible structural members and concealed spaces can allow fast extension and early collapse risk.

Question 42

Collapse indicators

Accepted Answer

Watch for wall cracks, leaning walls, sagging roofs or floors, unusual noises, spongy floors, and structural members distorted by heat.

Question 43

Irons

Accepted Answer

The irons are a Halligan tool and flat-head axe used together for forcible entry. They give prying, striking, spreading, and lock-defeating options.

Question 44

Ladder 4-to-1 rule

Accepted Answer

Place the ladder base about one foot out for every four feet of working height. This creates a stable climbing angle for most ground-ladder work.

Question 45

Ladder tip at roof edge

Accepted Answer

For roof access, extend the ladder several rungs above the roofline when local procedure permits. The visible tip helps firefighters find the ladder in smoke.

Question 46

Leg lock

Accepted Answer

A leg lock secures a firefighter on a ladder while both hands work. It must be practiced and used only when the ladder is properly placed and supported.

Question 47

Horizontal ventilation

Accepted Answer

Horizontal ventilation uses doors, windows, or fans to move smoke and heat out laterally. It must be coordinated with fire attack and flow-path control.

Question 48

Vertical ventilation

Accepted Answer

Vertical ventilation releases heat and smoke through openings above the fire. Roof work requires construction awareness, escape routes, and coordination with interior crews.

Question 49

Primary search

Accepted Answer

A primary search is rapid and targeted for life rescue during or soon after initial attack. Search survivable spaces first and communicate findings quickly.

Question 50

HazMat awareness role

Accepted Answer

Awareness-level responders recognize hazards, isolate the area, deny entry, notify appropriate resources, and avoid actions that spread contamination.
