STATIC WATER EXAM APPROVED QUESTIONS AND
CORRECT DETAILED ANSWERS WITH COMPLETE
SOLUTION
1. Which of the following elements is essential to consider when calculating the net
pump discharge pressure during water drafting operations?
The total volume of water available in the source
The atmospheric pressure and the elevation of the water source
The pump discharge pressure and the friction loss in the intake hose
The temperature of the water being pumped
2. What is the typical maximum flow rate that floating pumps are capable of achieving
when drawing from a sufficient water supply?
250 gallons per minute (GPM)
500 gallons per minute (GPM)
750 gallons per minute (GPM)
1000 gallons per minute (GPM)
3. What is the primary function of a cistern in fire suppression systems?
To store water for emergency use
To filter contaminants from water
To increase water pressure
To provide a source of irrigation
4. What is the main advantage of using low level strainers in fire suppression
operations?
They can operate effectively in deep water sources.
They allow for water drafting from very shallow water levels.
,They are designed to increase pump pressure significantly.
They are primarily used for backflushing purposes.
, 5. What is a key environmental consideration when selecting a water source for fire
suppression operations?
The proximity of the water source to urban areas
The potential impact on local wildlife and ecosystems
The availability of recreational activities nearby
The aesthetic value of the water source
6. What is a recommended method for firefighters to minimize the risk of falling through
ice during operations?
Using inflatable rafts for support
Distributing their weight with ground ladders
Wearing heavy gear to increase stability
Conducting operations only at night
7. In what way do larger static water supply sources provide advantages over smaller
sources during periods of low rainfall?
Larger sources maintain more consistent water levels and flow rates.
Larger sources are less likely to be affected by pollution.
Larger sources require less maintenance than smaller sources.
Larger sources can be accessed more easily by fire apparatus.
8. What height is typically recognized as a reliable lift for fire pumps, and what does this
height signify for fire suppression operations?
10 feet, indicating minimal water flow
14.7 feet, indicating the maximum height for effective water delivery
20 feet, indicating a significant reduction in pump efficiency
30 feet, indicating an optimal pressure for fire suppression
9. What are the implications of drafting water from a frozen body of water during fire
suppression efforts?
It can lead to increased pump efficiency due to colder water temperatures.
