What is a shove knife designed to do?

  • Depress the latch of an outward swinging door

  • Remove lock cylinders

  • Remove locks with protective collars

  • Slide between double-swinging doors to disengage the lock

Correct answer: Depress the latch of an outward swinging door

A shove knife is designed to depress the latch of an outward swinging door. A shove knife closely resembles a wide-blade putty knife, but the shove knife has a notch in one side of the blade.

A K-tool is designed to pull lock cylinders. An A-tool is designed to force entry on locks with collars. A J-tool is designed to fit through double swinging doors.

122.

What fire service tool/equipment is used to protect building contents during fire suppression?

  • Salvage cover

  • Hose roller

  • Scupper

  • Thermal Imager (TI)

Correct answer: Salvage cover

Salvage covers are used to protect unaffected furniture and areas of the building. 

123.

What type of fire department personnel accountability system requires an accountability officer to record the time a firefighter enters a structure fire and the expected exit time from the structure according to the lowest reading SCBA air pressure in the team?

  • An SCBA tag accountability system

  • A passport accountability system

  • A computer-based/electronic accountability system

  • An audio/video accountability system

Correct answer: An SCBA tag accountability system

An SCBA accountability system uses a tag attached to a firefighter's self-contained breathing apparatus that provides data to the firefighter about the amount of time he can safely use the breathing apparatus in a specific IDLH atmosphere. An accountability officer records the time of entry and exit by figuring the amount of oxygen contained in the lowest tank in the group of firefighters.

A passport accountability system uses a tag passed from each firefighter to the accountability officer; it is then posted on a control board. This technique gives the accountability officer a good indication of who may still be unaccounted for, however, it doesn't give the firefighter a good estimate of the time of air remaining available for his SCBA.

A computer-based/electronic accountability system provides the greatest protection to hot zone firefighters. Firefighters are tracked digitally by a transmitter on their PPE. There is no such accountability system used in the fire service that is referred to as an audio/video accountability system on hot zone safety.

124.

Strategies are the strategic goals used to mitigate hazardous materials incidents. Which type of strategy is utilized when a hazardous material fire is allowed to burn until its fuel is completely consumed?

  • Nonintervention strategy

  • Offensive strategy

  • Defensive strategy

  • Intervention strategy

Correct answer: Nonintervention strategy

The nonintervention strategy allows the incident to run its course on its own.

The offensive strategy is one in which the responders take direct action against the hazardous material incident. The defensive strategy is one in which the responders work on confining the hazard to protect the public from exposure. Intervention strategy is not one of the three types of strategies used to mitigate hazardous materials incidents.

125.

A hazardous material’s vapor density is considered a critical property of the material. Which of the following best defines a material’s vapor density?

  • The weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and pressure

  • The material’s flash point, autoignition temperature, and flammable, combustible, or explosive range

  • The measurement of the material’s tendency to evaporate

  • The temperature at which the vapor pressure matches or exceeds the atmospheric pressure

Correct answer: The weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and pressure

A material’s vapor density is the comparison of pure vapor weight to dry air weight at equal volumes, temperature, and pressure.

A material’s flammability is the material’s flash point, autoignition temperature, and flammable, combustible, or explosive range. A material’s vapor pressure is the measurement of the material’s tendency to evaporate. A material’s boiling point is the temperature at which the vapor pressure matches or exceeds the atmospheric pressure.

126.

In a multi-story building, stairways that are considered a means of egress and are considered protected are critical components of the building's life safety system. Protected stairways are built of fire-rated construction and usually have what kind of fire rating?

  • 1 or 2 hour rating

  • Sprinklers

  • A roof mounted fan

  • Self opening doors

Correct answer: 1 or 2 hours rating

Because protected stairways are considered essential to the life safety systems of some buildings, they are required to be enclosed with fire-rated construction and to have a fire rating of 1 or 2 hours.

Sprinklers are not necessarily required in protected stairways.

A roof mounted fan is a part of a pressurized stairwell and is not considered part of a protected stairway.

Self opening doors are not part of a protected stairway installation. In fact, the doors should be self closing to maintain the integrity of the protection.

127.

Firefighters often must deal with incidents that involve bulk transport vehicles that are carrying flammable fuels. In many ways, approaching and mitigating these types of incidents is similar to bulk storage fires and spills, but there are differences that must be considered. Which of the following is not a consideration when dealing with a spill or fire involve a bulk transport carrier hauling flammable liquids?

  • Moving the bulk carrier to a safe location

  • Reduced water supplies

  • Vehicle instability

  • Contents identification

Correct answer: Moving the bulk carrier to a safe location

Firefighters should not consider trying to move the bulk carrier. This is a task reserved for trained technicians after the scene has been stabilized, the fire extinguished, and all hazards eliminated.

The possibility of reduced water supply, the instability of the vehicles involved, and difficulties involved in identifying the contents of the bulk carrier are all considerations that firefighters must take into account when dealing with a fire or spill involving a bulk carrier.

128.

A hazardous material’s flammability is considered a critical property of the material. Which of the following best defines a material’s flammability?

  • The material’s flash point, autoignition temperature, and flammable, combustible, or explosive range

  • The material’s gaseous, liquidity, or solidity condition

  • The amount of time a chemical is able to remain effective without dissipating

  • The ability of a substance to chemically respond to other substances

Correct answer: The material’s flash point, autoignition temperature, and flammable, combustible, or explosive range

A material’s flammability is the material’s flash point, autoignition temperature, and flammable, combustible, or explosive range.

A material’s state of matter is the material’s gaseous, liquidity, or solidity condition. A material’s persistence is the amount of time a chemical is able to remain effective without dissipating. A material’s reactivity is the ability of a substance to chemically respond to other substances.

129.

Which of the following is not an example of a personnel accountability system used in the fire service?

  • Firefighter Tracking System

  • Passport System

  • Computer-Based Electronic Accountability System

  • SCBA Tag System

Correct answer: Firefighter Tracking System

Passport System (sometimes called a tag system) is when company officers have a passport listing for every member of their crew.

Computer-Based Electronic Accountability Systems provide a greater level of safety that utilizes radio-based tracking or radar-based transmitters attached to PPE.

SCBA Tag System is a tag attached to each SCBA of each firefighter.

130.

Preparation for personal survival during firefighting operations is critical for firefighter safety. There are many aspects to personal preparation for operating safely on the fire ground. Firefighters should be aware of many things, but one of the most important is their PPE and how it can affect their ability to survive safely. 

Which of the following is a true statement about PPE?

  • PPE has limitations and cannot protect from all hazards

  • PPE is fire-resistant and will not burn under any conditions

  • PPE protects a firefighter's body from all high-heat sources for an extended period

  • PPE is designed to allow a firefighter's body heat to escape

Correct answer: PPE has limitations and cannot protect from all hazards

PPE has limitations and cannot protect from all hazards. While it is designed to protect firefighters from heat, flames, and other hazardous conditions, PPE cannot provide complete protection against every potential danger. Firefighters must always work within safety protocols and understand the limitations set by the manufacturer.

PPE is not entirely fire-resistant under extreme conditions and can deteriorate or fail when exposed to high temperatures for too long.

PPE does not protect indefinitely from all heat sources and can only withstand certain levels of heat exposure before it becomes ineffective.

PPE is not fully breathable and does not allow complete escape of body heat, which can lead to heat stress during prolonged operations.

131.

Which type of hose roll is commonly used when transporting dirty hoses back to the station for cleaning?

  • Straight roll

  • Donut roll

  • Twin donut roll

  • Self-locking twin donut roll

Correct answer: Straight roll

A straight roll is the standard method for transporting dirty hoses back to the station for cleaning. This type of roll begins with the male coupling and rolls toward the female coupling, which is left on the outside of the roll. This method makes it easier to clean and inspect the hose, as the female coupling remains accessible.

A donut roll is typically used when the hose may need to be deployed directly from the roll, allowing for a quicker deployment. A twin donut roll is preferred for high-rise operations due to its compact size, which makes it easy to transport in tight spaces. A self-locking twin donut roll provides an integrated carrying loop, making it useful for carrying short sections of hose securely and conveniently.

132.

Which of the following best describes an indirect attack?

  • A fire attack made by directing the fire stream upward toward the ceiling to cool the room and reduce the heat throughout the space

  • Action taken on burning fuels by using a solid or straight stream to apply water directly to the burning fuels

  • A fire attack that uses an exterior attack through a ventilation opening to knock down flames from outside the building

  • The use of a water stream directed upward toward the ceiling while applying water directly to the burning fuel

Correct answer: A fire attack made by directing the fire stream upward toward the ceiling to cool the room

An indirect attack is a method where water is directed toward the ceiling or walls, which allows the water to absorb heat and cool the superheated gases. This reduces the temperature and helps control the fire in an enclosed space. This technique is often used when firefighters cannot directly access the seat of the fire due to high heat or poor visibility.

Direct attacks involve applying water directly to the burning fuels to extinguish the flames. A blitz attack is an aggressive exterior attack through a ventilation opening, commonly used when quick knockdown is required from outside. 

133.

Smooth-bore nozzles are a type of nozzle with a straight smooth bore and are used to produce a solid hose stream. All except which of the following are true regarding smooth-bore nozzles?

  • Prone to clogging with debris

  • Operate at low nozzle pressures

  • Favored for their simplicity

  • Allow kinking in hose line due to less pressure

Correct answer: Prone to clogging with debris

Smooth bore nozzles are less prone to clogging with debris because the unobstructed bore design reduces the likelihood of debris buildup. This makes them advantageous in environments where debris could otherwise impair water flow.

Smooth bore nozzles typically operate at lower nozzle pressures compared to fog nozzles, allowing for more manageable handling while still delivering high water flow rates. They are often preferred for their simplicity, as they have fewer moving parts, making them easier to use and maintain. They also allow some kinking in the hose line because of the lower operating pressure, although this can still affect the stream’s effectiveness.

134.

It was determined that lightning struck and caught the structure on fire. What type of fire would this be considered?

  • Natural

  • Accidental

  • Incendiary

  • Undetermined

Correct answer: Natural

Natural fires occur when humans are not involved in the ignition process. 

A fire caused by lightning is considered a natural fire. Natural fires are those that result without human involvement, such as lightning strikes, earthquakes, or tornados.

Accidental fires are deliberate and can result from unsafe human behavior or unsafe conditions. Incendiary fires are set when the individual knows what he/she is doing and can result in a criminal charge of arson. Undetermined fires' cause cannot be determined with a reasonable degree of probability due to a lack of evidence.

135.

Fire doors are used to protect openings in fire rated walls. The intent of installing fire doors in a structure is to prevent the spread of fire in a structure and can be found in all types of occupancies. Which of the following is not a characteristic of fire doors?

  • Must close automatically in case of a fire

  • Metal construction

  • Require special hardware

  • May roll into place

Correct answer: Must close automatically in case of a fire

While some fire doors are fitted with devices to cause them to close automatically in the event of a fire, it is not a requirement to meet the definition of a fire door.

Fire doors are generally constructed of metal and have special hardware and constructions. Fire doors may roll, slide or swing into place.

136.

In regard to the dry chemical agents used in dry chemical extinguishers, which of the following statements is accurate?

 

  • Dry chemical agents are nontoxic but can cause mild irritation or discomfort

  • Dry chemical agents cause severe burning sensations on the skin

  • Dry chemical agents can cause permanent blindness when inhaled

  • Dry chemical agents are completely non-corrosive

Correct answer: Dry chemical agents are nontoxic and safe to use

Dry chemical agents are generally nontoxic but can cause mild irritation to the skin, eyes, or respiratory system. While they are not inherently harmful when used correctly, users may experience coughing or minor discomfort when inhaled, as these chemicals are often fine powders.

Dry chemical agents do not cause severe burning sensations on the skin. However, they may cause mild irritation, which should not be confused with a burning sensation unless there is an allergic reaction. Dry chemical agents do not cause permanent blindness unless sprayed directly into the eyes, in which case it could lead to temporary discomfort or irritation.

Dry chemical agents can be mildly corrosive over time, particularly on certain surfaces or electronic equipment. They are not completely non-corrosive, which makes regular cleaning after usage important to prevent damage.

137.

When conducting a wide-area search, firefighters should use a search line carried in a rope bag and attached to an object outside the structure. The search line should have knots tied in the line at intervals to indicate the distance from the entrance. A steel ring may be attached to the line to allow firefighters to clip a tether line when searching areas perpendicular to the search line.  

Where should the steel rings be attached to the search line?

  • Just behind the knot

  • Two-thirds between the knots towards the exit

  • Halfway between the knots

  • Wherever a firefighter attaches a tether to do a lateral search

Correct answer: Just behind the knot

Placing the steel ring just behind the knot allows firefighters to easily and quickly determine which way to turn to; either go toward the fire or the exit. The knot should always be on the side going toward the fire, and the steel ring always be on the side of the search line that will lead to the exit.

A ring placed between the knots does not help in determining the correct path to the fire or the exit.

Two-thirds between the knots towards the exit is not a placement of steel rings. Firefighters do not attach rings during a search and rescue. The rings and knots should already be in place on a search line before it is deployed.

138.

Which of the following pieces of hardware is designed to create a mechanical advantage when hoisting objects?

  • Pulley

  • Carabiner

  • Edge roller

  • Eye loop

Correct answer: Pulley

A pulley creates a mechanical advantage when hoisting objects by redirecting force, making it easier to lift heavy loads with less effort. A system of multiple pulleys (block and tackle) increases this advantage further, reducing the effort required to lift even heavier objects.

A carabiner is used to connect ropes or equipment but does not provide a mechanical advantage in lifting.

An edge roller prevents rope damage by guiding it over the edges but does not aid in hoisting or lifting.

An eye loop is used to secure ropes but has no function in creating mechanical advantage.

139.

What is the standard distance to keep ground ladders and/or aerial devices away from power lines?

  • At least ten feet 

  • At least eight feet

  • From five to ten feet

  • At least 15 feet

Correct answer: At least ten feet 

Stay at least ten feet (three meters) away from power lines when raising or lowering ground ladders or aerial devices.

140.

You are leading the fire attack on a vehicle fire that is fully engulfed. As the lead on the fire hose, how should you approach the vehicle?

  • Approach the rear corner at a 45-degree angle from upwind/uphill when possible

  • Approach the front of the vehicle at a 90-degree angle from upwind/uphill if possible

  • Approach the rear of the vehicle at a 90-degree angle from downhill/downwind if possible

  • Approach the front of the vehicle at a 45-degree angle from downwind/downhill if possible

Correct answer: Approach the rear corner at a 45-degree angle from upwind/uphill when possible

When attacking a vehicle fire, approach the corner of the vehicle at a 45-degree angle to its side. Also, approach from upwind and/or uphill if at all possible. This is to prevent being struck by large pieces of shrapnel if the vehicle explodes.

Approaching the front or rear of a fully engulfed vehicle at a straight 90-degree angle and not approaching the corners is likely to put yourself and others in the most dangerous spot(s) possible. Do not attempt this type of approach, even when wind direction is working against you. Do not approach a vehicle fire from downwind or downhill to prevent coming in direct contact with possible fire, smoke (blowing downwind), and liquid from the vehicle (flowing downhill).
