Foam extinguishes fire in several ways. Term: Cooling Definition: _____________
- Intervening between the fuel and the fire
- Reducing the temperature of the fuel and adjacent surfaces
- Preventing air and flammable vapors from combining
- Establishing a perimeter for foam concentrate
Correct Answer

A. Reducing the temperature of the fuel and adjacent surfaces

Explanation

Foam extinguishes fire by reducing the temperature of the fuel and adjacent surfaces. When foam is applied to a fire, it creates a cooling effect that lowers the temperature, making it more difficult for the fire to sustain itself and spread. This cooling action helps to prevent the fire from reigniting and also protects nearby surfaces from heat damage. By reducing the temperature, foam helps to control and extinguish the fire effectively.

The engine brake and retarder are activated when:
- The brake pedal is applied too hard.
- The brake system fails.
- Pressure is released from the accelerator.
- The engine is first started.
Correct Answer

A. Pressure is released from the accelerator.

Explanation

When pressure is released from the accelerator, the engine brake and retarder are activated. This means that when the driver takes their foot off the accelerator pedal, the engine brake and retarder system kicks in to slow down the vehicle. This is a common feature in many vehicles, especially those equipped with heavy-duty engines or used for towing or hauling heavy loads. The engine brake and retarder help to reduce the wear on the vehicle's regular braking system and provide additional control and stability when descending steep slopes or during prolonged braking.

Which of the following is a result of over-throttling?
- Overheating of engine coolant
- Additional fuel consumption and loss of power
- Oil thickening
- White smoke from the exhaust
Correct Answer

A. Additional fuel consumption and loss of power

Explanation

Over-throttling refers to the act of opening the throttle of an engine beyond its recommended limits. This can result in additional fuel consumption and loss of power. When the throttle is opened too much, the engine is forced to work harder, consuming more fuel than necessary. This excessive fuel consumption leads to a decrease in power output, as the engine struggles to cope with the increased load. Therefore, the correct answer is additional fuel consumption and loss of power.

Specific gravity is best defined as:
- The density of liquids in relation to water.
- Atmospheric pressure.
- The viscosity of water in relation to solids.
- Static pressure.
Correct Answer

A. The density of liquids in relation to water.

Explanation

Specific gravity is a measure of the density of a substance in relation to the density of water. It is commonly used to compare the density of liquids to that of water, as water has a specific gravity of 1. If the specific gravity of a liquid is less than 1, it is less dense than water and will float, while a specific gravity greater than 1 indicates that the liquid is denser than water and will sink. Therefore, the correct answer is "the density of liquids in relation to water."

Correct Answer

A. Determining the percentage of foam concentrate.

Explanation

Flowmeters are devices used to measure the rate of flow of a liquid or gas. They are commonly used in various applications such as relay pumping, standpipe operations, and diagnosing water flow problems. However, determining the percentage of foam concentrate is not a suitable application for flowmeters. This is because foam concentrate is not a fluid that can be measured in terms of flow rate. Instead, the concentration of foam is typically determined by other means such as mixing ratios or chemical analysis. Therefore, flowmeters cannot assist in determining the percentage of foam concentrate.

While conducting a pump capacity test, if the net pump pressure is correct but the nozzle flow (gpm) is too high, the:
- Discharge gate must be opened further.
- Discharge gate must be closed further.
- Throttle setting must be reduced.
- Both B and C are correct.
Correct Answer

A. Both B and C are correct.

Explanation

If the net pump pressure is correct but the nozzle flow (gpm) is too high, it means that the pump is delivering the correct pressure but the flow rate is higher than desired. To reduce the flow rate, the discharge gate must be closed further, which restricts the flow of water. Additionally, the throttle setting must be reduced, which decreases the speed of the pump and subsequently reduces the flow rate. Therefore, both options B and C are correct as they both contribute to reducing the nozzle flow.

In drafting operations, pumping ability decreases when:
- Atmospheric pressure increases.
- Barometric pressure increases.
- Absolute pressure decreases.
- Atmospheric pressure decreases.
Correct Answer

A. Atmospheric pressure decreases.

Explanation

When drafting operations are conducted, the ability to pump water decreases when the atmospheric pressure decreases. This is because the atmospheric pressure plays a crucial role in creating a pressure difference that allows water to be drawn into the pump. When the atmospheric pressure decreases, the pressure difference also decreases, resulting in a reduced pumping ability. Conversely, an increase in atmospheric pressure would enhance the pressure difference and therefore improve the pumping ability.

The NFPA standard that gives direction for establishing a driver/operator training program is NFPA:
- 1561.
- 1560.
- 1451.
- 1450.
Correct Answer

A. 1451.

Explanation

NFPA 1451 is the correct answer because it provides guidelines for establishing a driver/operator training program. This standard specifically focuses on the qualifications, knowledge, and skills required for individuals operating fire apparatus and emergency vehicles. It outlines the necessary training curriculum, evaluation methods, and ongoing education requirements to ensure that driver/operators are competent and capable of safely and effectively performing their duties.

Indications of cavitation include all of the following except:
- Air escaping from pump vent.
- Increase in RPM will greatly increase pressure.
- Vibration.
- Fluctuating gauge readings.
Correct Answer

A. Air escaping from pump vent.

Explanation

Indications of cavitation in a pump include an increase in RPM greatly increasing pressure, vibration, and fluctuating gauge readings. However, air escaping from the pump vent is not an indication of cavitation. Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing the formation of vapor bubbles that collapse and cause damage to the pump. Air escaping from the pump vent could indicate a different issue, such as a leak or improper venting, but not cavitation.
