Hose, Streams, & Appliances
Will test the Firefighters knowledge of Hoses, Streams, and Appliances as it applies to the Fire Service.
- 1.
Fire stream is defined as
- A.
A stream of water or other extinguishing agent from the time it leaves the nozzle or other discharge orifice until it reaches the desired point in the proper configuration.
- B.
The stream of fire that comes out of a flame thrower
- C.
The after effects of eating spicy foods
- D.
Both B & C
Correct Answer
A. A stream of water or other extinguishing agent from the time it leaves the nozzle or other discharge orifice until it reaches the desired point in the proper configuration.Explanation
The correct answer is A. A fire stream is defined as a stream of water or other extinguishing agent from the time it leaves the nozzle or other discharge orifice until it reaches the desired point in the proper configuration. This definition refers to the flow of water or extinguishing agent used to combat fires and ensure that it reaches the intended target effectively. The other options, B and C, are incorrect as they do not accurately describe a fire stream.Rate this question:

- 2.
Which are types of fire streams
- A.
Solid stream
- B.
Broken Stream
- C.
Fog stream
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above" because all three types of fire streams mentioned in the options - solid stream, broken stream, and fog stream - are commonly used in firefighting. A solid stream is a direct, concentrated stream of water used to reach long distances, a broken stream is a dispersed stream used for ventilation and cooling, and a fog stream is a fine mist used for extinguishing fires and protecting firefighters. Therefore, all three types are valid options for fire streams.Rate this question:

What is the proper operating pressure for a solid stream nozzle
- A.
70 psi
- B.
60 psi
- C.
50 psi
- D.
100 psi
Correct Answer
C. 50 psiExplanation
The proper operating pressure for a solid stream nozzle is 50 psi. This pressure allows for an effective stream of water to be produced, ensuring that the nozzle can effectively reach its target and provide the desired water flow. Operating at a lower pressure may result in a weak or ineffective stream, while operating at a higher pressure may cause excessive force or damage to the target. Therefore, 50 psi is the optimal pressure for a solid stream nozzle.Rate this question:

Adjustable Fog nozzles
- A.
Are easy to handle
- B.
Produces pattern that can vary from straight stream to wide angle fog
- C.
Produces little water flow
- D.
Has an operating pressure of 50 psi
Correct Answer
B. Produces pattern that can vary from straight stream to wide angle fogExplanation
Adjustable fog nozzles are designed to provide flexibility in controlling the pattern of the water spray. They can be adjusted to produce a straight stream or a wide angle fog, depending on the needs of the situation. This versatility allows the user to adapt the nozzle to different firefighting scenarios, such as directing a concentrated stream of water to reach a specific target or creating a wider spray to cover a larger area. The other statements about being easy to handle, producing little water flow, and having an operating pressure of 50 psi do not accurately describe the main characteristic of adjustable fog nozzles.Rate this question:

Fire hose is generally classified by its
- A.
Color
- B.
Weight
- C.
Diameter
- D.
Length
Correct Answer
C. DiameterExplanation
Fire hose is generally classified by its diameter. Diameter is an important factor in determining the water flow rate and pressure that the hose can handle. A larger diameter allows for more water to flow through the hose, resulting in a higher flow rate. This is crucial in firefighting situations where a large volume of water is needed to extinguish the fire effectively. Additionally, a larger diameter hose can handle higher pressure, which is important for ensuring that the water reaches the desired location with sufficient force. Therefore, the diameter of the fire hose is a key characteristic used for classification.Rate this question:

Hose coupling parts include all of the following except
- A.
Thread chaser
- B.
Shanks
- C.
Swivels
- D.
Threads
Correct Answer
A. Thread chaserExplanation
The correct answer is "Thread chaser" because hose coupling parts typically include shanks, swivels, and threads, but a thread chaser is not a part of a hose coupling. A thread chaser is a tool used to clean or repair damaged threads, but it is not a component of the coupling itself.Rate this question:

When using hose clamps you should never
- A.
Straddle hose clamps while operating the device
- B.
Place the hose in the jaws of the clamp
- C.
Apply 3 to 5 feet from the supply side of a coupling on the fire hose
- D.
When using a level clamp stand to the side of the clamp and press the level down and release the catch on the under side of the lever
Correct Answer
A. Straddle hose clamps while operating the deviceExplanation
When using hose clamps, it is important to not straddle them while operating the device. This means that you should not position yourself in a way that you are sitting or standing directly on top of the hose clamps while using them. This is because straddling the hose clamps can put unnecessary pressure on them and potentially cause them to break or malfunction. It is safer to stand to the side of the clamp while operating it to ensure proper functioning and avoid any accidents.Rate this question:

Which roll is not a type of hose roll
- A.
Straight roll
- B.
Quint roll
- C.
Donut roll
- D.
Twin Donut roll
Correct Answer
B. Quint rollExplanation
The question asks for a type of hose roll that is not included in the given options. The options include Straight roll, Donut roll, and Twin Donut roll. The correct answer is Quint roll, which is not a type of hose roll. Therefore, Quint roll is the answer.Rate this question:

When operating a nozzle the firefighter should
- A.
Wear proper PPE
- B.
Hold the hose in one hand and the nozzle in the other
- C.
Both a & b
- D.
Slam the nozzle open and closed to minimize the time needed to open and close the nozzle
Correct Answer
C. Both a & bExplanation
When operating a nozzle, it is important for the firefighter to wear proper personal protective equipment (PPE) to ensure their safety. Additionally, they should hold the hose in one hand and the nozzle in the other to have better control and aim. Therefore, the correct answer is "Both a & b" as both options are necessary for the firefighter to effectively operate the nozzle.Rate this question:
