    The term rollover is defined as that period in a fire when:

    • Flames flash across the ceiling

    • Flames flash across the top of a flammable liquid

    • The entire contents of a room or area is fully involved in fire

    • Flames roll across the ceiling in an area

    Correct Answer
    A. Flames roll across the ceiling in an area
    Explanation
    Rollover refers to the phenomenon where flames move across the ceiling in a specific area during a fire. This occurs when the hot gases and flames accumulate near the ceiling, creating a layer of intense heat. When this layer becomes unstable, it can ignite and cause flames to roll or move rapidly across the ceiling. This is a dangerous situation as it can lead to the rapid spread of fire and increased heat release, posing a significant threat to both occupants and firefighters.

    The ____ system is ordinarily equipped with all sprinkler heads of the open type.

    • Wet pipe

    • Dry pipe

    • Deluge

    • Pre action

    Correct Answer
    A. Deluge
    Explanation
    The deluge system is ordinarily equipped with all sprinkler heads of the open type. Unlike other systems like wet pipe, dry pipe, and pre-action, the deluge system does not have individual sprinkler heads that are activated by heat. Instead, all the sprinkler heads in a deluge system are open and will release water simultaneously when the system is triggered. This type of system is commonly used in high hazard areas where rapid fire suppression is necessary, such as in chemical or industrial facilities.

    The term "grid" is sometimes used to describe a network of water mains that make up a distribution system.  Which of the following violates the principle of a grid system?

    • Primary feeders

    • Secondary feeders

    • Inter connecting distributors

    • Dead end water mains

    Correct Answer
    A. Dead end water mains
    Explanation
    Dead end water mains violate the principle of a grid system because they do not provide multiple paths for water to flow. In a grid system, water mains are interconnected in a network, allowing water to flow in multiple directions and ensuring redundancy in case of a break or maintenance. Dead end water mains, on the other hand, are water mains that do not have any further connections beyond their endpoint, resulting in a single point of entry and exit for water. This can lead to lower water pressure and difficulties in water distribution.

    Which of the following types of portable fire extinguishers is the LEAST LIKELY to expose the operator to electrical shock?

    • Dry chemical

    • Wet chemical

    • Stored pressure AFFF

    • FFFP foam

    Correct Answer
    A. Dry chemical
    Explanation
    Dry chemical fire extinguishers are the least likely to expose the operator to electrical shock because they contain a dry powder that is non-conductive. This means that it does not conduct electricity and therefore does not pose a risk of electrical shock when used on electrical fires. Wet chemical, stored pressure AFFF, and FFFP foam fire extinguishers may contain water or other conductive substances, which can increase the risk of electrical shock if used on electrical fires.

    The part of total pressure that is lost while forcing water through pipe, fittings, fire hose, and adapters is called:

    • Residual pressure

    • Flow pressure loss

    • Friction loss

    • Static pressure

    Correct Answer
    A. Friction loss
    Explanation
    Friction loss refers to the part of total pressure that is lost while forcing water through various components such as pipes, fittings, fire hose, and adapters. This loss occurs due to the resistance encountered by the water as it flows through these components, resulting in a decrease in pressure. Therefore, friction loss is the correct term to describe this phenomenon.

    ______ deposits consist of mud, clay, and dead organisms.

    • Rust

    • Sedimentary

    • Tuberculation

    • Encrustation

    Correct Answer
    A. Sedimentary
    Explanation
    Sedimentary deposits are formed by the accumulation of mud, clay, and dead organisms over time. These materials settle and compact, eventually forming layers of sedimentary rock. Rust is a type of corrosion that occurs on metal surfaces, and it is not related to the formation of sedimentary deposits. Tuberculation refers to the formation of small protuberances on the surface of pipes, and encrustation refers to the accumulation of mineral deposits on surfaces. Therefore, the correct answer is sedimentary.

    A local protective signaling system is intended PRIMARILY to alert:

    • The fire department dispatcher

    • A private alarm contractor

    • Occupants of the protected area

    • Central monitoring station

    Correct Answer
    A. Occupants of the protected area
    Explanation
    A local protective signaling system is primarily intended to alert the occupants of the protected area. This system is designed to provide immediate notification to the individuals present in a specific location in the event of an emergency or threat. By alerting the occupants, they can take necessary actions to evacuate or seek safety, ensuring their well-being and minimizing potential harm. The system may also have secondary purposes, such as notifying the fire department dispatcher, a private alarm contractor, or a central monitoring station, but its primary function is to alert the occupants directly.

    Energized electrical equipment and the surrounding area are BEST protected with extinguishers that have a ______ rating.

    • Class A

    • Class B

    • Class C

    • Class D

    Correct Answer
    A. Class C
    Explanation
    Energized electrical equipment and the surrounding area are best protected with extinguishers that have a Class C rating. Class C fires involve energized electrical equipment, so it is important to use extinguishers specifically designed for these types of fires. Class C extinguishers are non-conductive and contain agents that are safe to use on electrical fires, effectively extinguishing the flames without the risk of electrical shock.

    Which of the following IS NOT suggested for courtroom procedure or behavior?

    • Never become argumentative on the witness stand

    • Make sure that all physical evidence, exhibits, photographs, notes, and reference materials are brought to court

    • Attempt to answer a question you do not know

    • Remain impartial. Do not give the impression that you have a personal dislike for the defendant

    Correct Answer
    A. Attempt to answer a question you do not know
    Explanation
    It is not suggested to attempt to answer a question you do not know in a courtroom procedure or behavior. It is important to be truthful and provide accurate information during legal proceedings. If you do not know the answer to a question, it is better to admit it rather than providing incorrect or misleading information.
