CHAPTER 1 JESSE QUESTIONS WITH COMPLETE SOLUTION
1. Which of the following statements about water sources for fire department pumpers is
MOST accurate?
Water sources include residential faucets, fire hydrants and dedicated water
sources.
Static water sources may be contaminated so should never be used for fire
department pumpers.
Water sources include the apparatus internal water tank, fire hydrants and
static water sources.
The water source for fire department pumpers always comes from the
apparatus water tank.
2. What is the primary purpose of color coding on fire hydrants?
To indicate the age of the hydrant
To show the location of the hydrant
To indicate the available flow rate
To identify the manufacturer of the hydrant
3. The primary function of a fire hydrant is to:
controls head loss in the distribution system
provides fire protection
flush the distribution system
serve as a maintenance water supply for the city clean up
none of the above
4. What kinds of problems can result from illegally opened fire hydrants?
Consumers can suffer damages due to a lack of water and pressure
Damage due to flooding and washouts
,Loss of water results in a loss of revenue for the water utility
Vandalism decreases in the community
, Water may not be available to fight fires when needed
5. What is the primary reason for draining water from a fire hydrant after use in cold
weather?
To reduce water pressure in the system
To prevent freezing and potential damage
To clean the hydrant for better performance
To ensure proper water flow during the next use
6. In a rural area lacking a municipal water supply, how might the design of fire hydrants
differ from those in urban settings, and what implications does this have for
firefighting?
Rural fire hydrants would have larger outlet sizes to accommodate tankers.
Rural fire hydrants may not exist; instead, portable tanks and tankers are
used for water delivery.
Rural fire hydrants would be made of lighter materials to facilitate transport.
Rural fire hydrants would include additional valves for better pressure control.
7. In a scenario where a fire breaks out in a region with both wet-barrel and dry-barrel
fire hydrants, how would the presence of wet-barrel hydrants impact the response
time of firefighters?
Firefighters would have to wait for water to fill the dry-barrel hydrants.
Firefighters can immediately access water from wet-barrel hydrants.
Firefighters would prefer dry-barrel hydrants for their higher pressure.
Firefighters would need to drain the wet-barrel hydrants before use.
8. What is the primary function of underground water mains in municipal water systems?
To treat water before distribution
To transport water to treatment facilities
To provide water for irrigation purposes
To transport water to ensure supply for public use and firefighting
, 9. What is the definition of normal operating pressure in a water distribution system?
The maximum pressure that can be sustained in the system.
The pressure during a period of normal water consumption.
The pressure required to activate fire hydrants.
The pressure measured at the water source.
10. Which of the following are consequences of fire-induced hydrophobic layers in soil?
Roots cannot penetrate the layer
Increased erosion
"Flashy" hydrologic behavior
B and C
All are consequences
11. Explain how a dry-barrel fire hydrant prevents freezing in cold weather conditions.
It uses heated water to maintain a constant temperature.
It has a valve at the top that prevents water from entering.
It drains water from the barrel after use to avoid ice formation.
It is insulated to keep the water warm.
12. What is the main access point for the fire department water supply in municipal water
systems?
Pools, rivers and ponds
Dump tanks and water tankers
Hydrants
Water shuttle operations
13. What is the definition of elevation pressure in the context of water supply systems?
The pressure exerted by water at a specific temperature.
The pressure change due to the height difference in a water supply system.
The total pressure in a water distribution system.
