61.

You arrive on the scene of a high-rise office building. An elevator car is stuck between floors. The occupants are communicative and are under no serious stress or threat and report no medical problems. What might be the best alternative in this situation?

  • Reassure the car occupants and wait for elevator technicians to arrive

  • Force the elevator doors open and remove the occupants

  • Open the maintenance door on the top of the car

  • Raise or lower the car from the mechanical room

Correct answer: Reassure the car occupants and wait for elevator technicians to arrive

If there is no immediate threat to life, the option to wait for trained elevator technicians may be the safest alternative. This option puts neither the occupants of the car at risk, nor does it put firefighters at risk.

Forcing the doors open and pulling victims through the opening puts the victims are risk and firefighters at risk working around the open elevator shaft.

The maintenance opening in an elevator car is not a viable option. It puts firefighters at risk working on top of the elevator car and requires moving the victims upward.

There is no way to manually raise or lower an elevator car with the equipment that fire department rescue teams normally carry.

62.

A vehicle generally contains safety glass and tempered glass. Which of the following is true in regard to tempered glass?

  • It crumbles into chunks

  • It is stronger than safety glass

  • It is generally used in windshields

  • It is laminated to a sheet of plastic

Correct answer: It crumbles into chunks

Tempered glass crumbles into chunks, as it is treated to prevent it from splintering into jagged shards.

Safety glass is stronger than tempered glass. Tempered glass is generally used in side and rear windows, not windshields. Tempered glass is treated glass, not laminated to a sheet of plastic.

63.

When doing an initial risk assessment, which of the following can be said to be better from a risk-management perspective in relationship to hazmat incidents when establishing the initial isolation perimeter?

  • It is better to encompass a larger area that can be reduced in size than try to enlarge an isolation perimeter later in the incident

  • Establish as many isolation perimeters as the situation needs to enclose the possible areas of contamination and the greatest danger

  • Never change the isolation perimeter so that personnel will not become confused about where the perimeter is established

  • Mark the isolation perimeter only with yellow hazard tape so that everyone is aware of where the boundary is located

Correct answer: It is better to encompass a larger area that can be reduced in size than try to enlarge an isolation perimeter later in the incident

Once resources have been committed to a hazmat incident, it can be almost impossible to disengage them from assigned tasks and move them if the isolation perimeter must be expanded. Making the isolation perimeter larger in the beginning is better, as it is easier to shrink the isolation perimeter if conditions warrant.

Only one isolation perimeter should be established around a hazmat incident.  

Isolation perimeters can be changed, enlarged or shrunk, as needed. It is easier to shrink then enlarge an isolation perimeter.

The method of marking the isolation boundary is a matter of operational procedure and has nothing to do with risk-assessment or risk-management.

64.

Which of the following is not an example of a combustible metal or alloy?

  • Textiles

  • Titanium

  • Potassium

  • Lithium

Correct answer: Textiles

Textiles are non-metallic materials and are not classified as combustible metals or alloys. They may be flammable but do not belong to the category of combustible metals (Class D fires), which includes metals like magnesium, titanium, and others.

Titanium is a combustible metal that can ignite and burn under certain conditions, such as when finely divided or exposed to heat. 

Potassium is a highly reactive alkali metal that can ignite spontaneously in water or air, making it a combustible metal. 

Lithium is another combustible alkali metal, particularly in air or moisture. It is used in batteries where it poses fire risks.

65.

Which type of roof ventilation cut is primarily used to assess interior conditions while maintaining minimal impact on the overall ventilation profile?

  • Kerf cut

  •  Panel cut

  • Louvre cut

  • Trench cut

Correct answer: Kerf cut

A kerf cut involves making a small slit, typically the width of a saw blade, into the roof. It’s primarily used for assessing interior conditions like smoke or fire presence with minimal alteration to the building's ventilation. This cut is advantageous when firefighters want to evaluate conditions without immediately altering the fire’s behavior by adding significant airflow.

 A panel cut is not a known ventilation cut.  A louver cut is a roof ventilation cut that creates a shield for responders, as well as opening vertical ventilation. A trench cut is a roof cut used to create a fire break to prevent fire from spreading within the attic structure.

66.

Once the primary search is conducted at a structure fire, firefighters conduct a secondary search. Which of the following statements is false regarding the secondary search?

  • The same firefighters who conducted the primary search will conduct the secondary search

  • The secondary search is slower and more thorough

  • The secondary search is conducted after the initial fire suppression and ventilation have been completed

  • The firefighters during the secondary search verify that no occupants were overlooked during the primary search

Correct answer: The same firefighters who conducted the primary search will conduct the secondary search

It is false that the same firefighters who conducted the primary search will conduct the secondary search. The secondary search is typically conducted by a different crew of firefighters to provide a fresh perspective and ensure that nothing was missed during the primary search. The secondary search is critical because it is more deliberate and cautious, ensuring no victims or hazards remain undetected.

The secondary search is slower and more thorough because it is conducted once immediate hazards are controlled, allowing for more careful scrutiny of the structure.

The secondary search occurs after the initial fire suppression and ventilation operations to ensure conditions are safe for firefighters to conduct a detailed examination of the premises.

The purpose of the secondary search is to confirm that no occupants or victims were missed during the primary search, which is often performed quickly under hazardous conditions.

67.

Which type of roof ventilation cut allows firefighters to gain the most reliable view of the structure’s conditions below?

  • Triangle cut

  • Kerf cut

  • Louver cut

  • Trench cut

Correct answer: Triangle cut

A triangle cut is a roof ventilation cut that allows firefighters to gain the most reliable view of the structure’s conditions below.

A kerf cut is a thin, saw blade-wide roof ventilation cut that allows firefighters to assess the structure’s conditions below without significantly changing the ventilation profile.

A louver cut is a roof ventilation cut that creates a shield for responders, as well as opening vertical ventilation.

A trench cut is a roof cut used to create a fire break to prevent fire from spreading within the attic structure.

68.

Rescue tools can get their power from several different sources. Which of the following is not a common source of power for fire department rescue power tools?

  • Water flow

  • Hydraulic

  • Pneumatic

  • Electric

Correct answer: Water flow

Water flow is not normally a powersource used to operate rescue equipment.

Hydraulic, electric, and pneumatic are the common types of power used for fire department rescue tools.

69.

Attack and supply fire hoses are both manufactured in which of the following lengths? 

  • 50 or 100 feet

  • Up to 660 feet

  • 10 feet

  • Minimum of 15 feet

Correct answer: 50 or 100 feet

Attack and supply fire hoses are both manufactured in lengths of 50 or 100 feet. Attack fire hoses are manufactured using 1.5 to 3-inch diameters. Supply fire hoses are manufactured using 2.5 to 6-inch diameters.

Industrial supply fire hoses are manufactured in lengths of up to 660 feet. Hard suction hoses are manufactured at 10 feet. Soft sleeve hoses are manufactured using a minimum length of 15 feet.

70.

Booster fire hoses are manufactured in which of the following diameters?

  • 0.75 inch to 1 inch

  • 1.5 inches to 3 inches

  • 2.5 inches to 6 inches

  • 1 inch to 1.5 inches

Correct answer: 0.75 inch to 1 inch

Booster fire hoses are typically used for extinguishing small fires and are manufactured in diameters ranging from 0.75 inches to 1 inch. These hoses are often lightweight and stored on reels, making them ideal for quick deployment. They are commonly used in situations where a smaller, more maneuverable hose is necessary.

Attack fire hoses, which are used to fight active fires, are manufactured in larger diameters, typically from 1.5 inches to 3 inches. Supply fire hoses, used to deliver large volumes of water over long distances, come in diameters ranging from 2.5 inches to 6 inches. Forestry fire hoses, designed for use in wildland firefighting, are generally smaller, with diameters from 1 inch to 1.5 inches.

71.

Emergency personnel should adhere to the ABCs of good communication. What are the ABCs of good communication?

  • Accurate, Brief, and Concise

  • Audible, Basic, and Clear

  • Articulate, Breathe, and Confident

  • Accountable, Basic, and Calm

Correct answer: Accurate, Brief, and Concise

The ABCs of good communication are Accurate, Brief, and Concise. Emergency personnel should make sure their message is heard and understood. The sender should make sure he or she knows exactly what they are going to say before they open their microphone.

The other options are incorrect because the ABCs of communication are accurate, brief, and concise.

72.

Safety during overhaul operations is the primary concern. Which of the following is not part of maintaining situational awareness during overhaul operations?

  • Ventilate every compartment in the structure that has an exterior opening

  • Operate in teams of two or more

  • Monitor personnel rehabilitation needs

  • Watch for still operating utilities

Correct answer: Ventilate every compartment in the structure that has an exterior opening

It is not necessary to ventilate every compartment in some structures. Where there is no evidence of fire extension or heavy smoke concentrations, it may not be necessary to remove windows in those areas.

Firefighters should always operate in teams of two or more, including overhaul operations.

Be aware of the need for personnel rehabilitation as a long incident wears on and firefighters begin to fatigue.

Watch for electrical utilities that may be live and gas utilities that may be leaking.

73.

Who can view fire incident reports?

  • General public

  • AHJ tax-paying residents

  • First responders

  • Firefighters

Correct answer: General public

From legal, statistical, and record-keeping standpoints, incident reports are vital to fire department operations. Because reports are available to the public, they must be complete and written in terminology that the general public can understand.

74.

A firefighter arrives at a scene where a type II structure is on fire. In regard to determining the collapse zone, the firefighter knows which of the following to be true for this structure?

  • Its walls could be pushed out due to its steel I-beams expanding and twisting

  • Its primary concern is flying glass from windows

  • It is the structure type least likely to collapse

  • It could collapse inward if it is a platform-frame structure or outward if it is a balloon-frame structure

Correct answer: Its walls could be pushed out due to its steel I-beams expanding and twisting

When determining the collapse zone for a type II structure, the firefighter should know that its walls could be pushed out due to its steel I-beams expanding and twisting. Type II building construction contains structural components able to resist fire for 1 to 2 hours.

Its primary concern is flying glass from windows is true for a type I structure. It is the structure type least likely to collapse is true for a type IV structure. It could collapse inward if it is a platform-frame structure or outward if it is a balloon-frame structure is true for a type V structure.

75.

Assembling a foam fire stream system requires some skill and training. The components of the system must be maintained, assembled, and operated correctly to produce an acceptable finished foam. Which of the following is not one of the most common reasons for a failure to produce a satisfactorily finished foam?

  • Using the wrong foam product

  • Mismatched flow ratings

  • Hose lays too long

  • Excessive nozzle elevation

Correct answer: Using the wrong foam product

The foam concentrate used does not affect the foam proportioning system used. If the system is assembled and operated properly, any type of foam for which it is rated can be used to create a satisfactorily finished foam.

When the flow rating between the eductor and the nozzle does not match, the eductor may not be able to induct the foam concentrate into the fire stream.

The length of the hose lay may prevent the eductor from proportioning the foam concentrate correctly by inducing backpressure into the system.

Excessive elevation on the nozzle may induce elevation pressure, which can cause the eductor to fail to operate.

76.

The fire resulted in total destruction of the structure, and the ignition sequence was unidentifiable. What type of fire would this be considered?

  • Undetermined

  • Accidental

  • Natural

  • Incendiary

Correct answer: Undetermined

When a fire’s ignition sequence cannot be determined, it is considered an undetermined fire. Undetermined fires' cause cannot be determined with a reasonable degree of probability due to a lack of evidence.

Accidental fires are not deliberate and can result from unsafe human behavior or unsafe conditions. Natural fires result without human involvement, such as lightning strikes, earthquakes, or tornados. Incendiary fires are set when the individual knows what he/she is doing and can result in a criminal charge of arson.

77.

Which operational strategy involves diking, damming, or diverting actions?

  • Defensive

  • Offensive

  • Nonintervention

  • Intervention

Correct answer: Defensive

The three types of operation strategy are: 

  • Nonintervention - Allows the incident to run its course on its own
  • Defensive - Provides confinement of the hazard to a given area by performing diking, damming, or diverting actions
  • Offensive - Includes actions, such as plugging a leak, to control the incident

78.

A drain valve is an operating valve best described by which of the following?

  • A valve that permits piping to drain once the pressure in the pipe is relieved

  • A valve that visually shows the open or closed status

  • A valve that transmits a water-flow alarm when the valve clapper is lifted by water flow

  • A valve that permits water to only flow in one direction

Correct answer: A valve that permits piping to drain once the pressure in the pipe is relieved

A drain valve is an operating valve that permits piping to drain once the pressure in the pipe is relieved.

An indicating valve is a control valve that visually shows the open or closed status. An alarm check valve is an operating valve that transmits a water-flow alarm when the valve clapper is lifted by water flow. A check valve permits water to only flow in one direction.

79.

A material used for wallcoverings in many structures is known for it high water content that absorbs large amounts of heat as the water evaporates. This property provides excellent heat-resistance and fire retardent abilities. Which of the following is not a term by which this product is known?

  • MDF

  • Drywall

  • Gypsum

  • Sheetrock

Correct answer: MDF

MDF, or medium density fiberboard, is a product made of sawdust and a bonding agent pressed together to form a sheet that is highly stable in almost every direction. It will disintegrate over time when exposed to water and may give off toxic gases when burned.

Gypsum, drywall, or sheetrock are the terms most commonly used for the material described.

80.

Which of the following would suggest that a patient's bleeding is arterial and not a venous bleed?

  • Spurting or pulsing blood

  • Steady flow of blood

  • Arterial blood is darker than venous blood

  • Arterial bleeding will be minimal compared to the other two types of bleeds

Correct answer: Spurting or pulsing blood

Arterial bleeding can be identified when the blood is bright red and spurting or pulsing. This spurting bleeding coincides with each contraction of the heart. Patients with venous bleeding will have a steady flow of blood. The venous blood will be much darker than arterial blood because oxygen has been removed by the cells and carbon dioxide and waste have been added.
