7) Two company officers discussing high rise fire pumps were able to agree on all points below except which incorrect statement? (HR 4.1.1 B, 4.1.3 A, 4.1.8 C, 4.1.8 E)
A) The 1968 Building Code requires a manual fire pump to supplement the standpipe system in buildings over 300 feet high. The 1938 Building Code requires a manual fire pump in buildings over 250 high.
B) The control cabinet for a 750 gallon fire pump will be in the shape of a large cube. It varies from 6’ x 6’ x 6’ to as large as 8’ x 8’ x 8’ in the older models.
C) Pump capacity is usually 750 gpm. Most high-rise buildings have two pumps side by side which are connected in the parallel position.
D) Some buildings have a combination standpipe/sprinkler system with the siamese connected to both systems. The usual arrangement for the fire pumps is that both will be automatic. The automatic fire pumps will be of larger capacity (1000 gpm).
- D
E. Some buildings have a combination standpipe/sprinkler system with the
siamese connected to both systems. The same starting procedures will
apply in these buildings. The usual arrangement for the fire pumps is that
one will be automatic and one manual. The automatic fire pumps may be
of smaller capacity (250 gpm or 500 gpm).
8) The operation of manual pumps in the pump room of a high-rise building can be quite complex. Of the following choices, an experienced officer should know which to be incorrect? (HR 4.1.2 C, D, E)
A) Locate the bypass valve on the discharge side of the fire pump. The discharge side can be readily identified by examining the gauges. The discharge gauge is calibrated for higher pressures than the inlet gauge.
B) The bypass valve should be in the closed position (stem in). Some engineers keep them open for test purposes, so they must be checked. If found to be open, they should be closed by turning in a clockwise direction.
C) It is permissible to start the pump without checking the bypass valve. Notify the engineer upon his/her arrival of this and any other actions taken. The efficiency of the pump will be affected if the bypass is open.
D) A loss of 45% can be expected in an 8” riser and a loss of 25% can be expected in a 6” riser with the bypass open
- D
A loss of 25% can be expected in an 8” riser and a loss of 45% can be expected in a 6” riser with the bypass open.

FIRE FLOORS PUMP DISCHARGE PRESSURE Floors 1 to 10 150 psi Floors 11 to 20 200 psi Floors 21 to 30 250 psi Floors 31 to 40 300 psi Floors 41 to 50 350 psi Floors 51 to 60 400 psi Floors 61 to 70 450 psi Floors 71 to 80 500 psi Floors 81 to 90 550 psi Floors 91 to 100 600 psi
10) Of the following choices, which contains incorrect information regarding the operation of high rise building fire pumps? (HR 4.1.8 F, G, H)
A) When a building is equipped with two manual fire pumps, as is the case in most high-rise buildings, each pump will have its own control panel. Both pumps shall be started and used.
B) Since fire pumps are connected in parallel position, it is necessary to have both pumps operating at or near the same pressures.
C) A visual check should be made of the discharge gauges of both pumps. When both are operating correctly, the pressures should be equal or nearly so.
D) Where one gauge reading is considerably lower than the other, the pumps must be shut down and allowed to cool for 5 minutes.
- D
H. Where one gauge reading is considerably lower than the other, the pressure can be increased on the less efficient pump by moving the pump position lever to a higher position.
11) Officers should have a working knowledge of building fire pumps. An experienced officer would know all points below to be correct except? (HR 4.2.1, 4.2.2, 4.2.3, 4.2.5)

1. Horizontal ventilation should be the last consideration as its effects are least likely to be beneficial.
2. Natural vertical ventilation (ventilation without the use of fans), is an option and may be accomplished by opening the doors at the top and bottom of the stairway once the fire is extinguished. This will increase the stack effect and assist in the removal of smoke via the stairway.
3. Stack effect becomes noticeable in buildings over 60 feet, and increases as the building’s height increases. Its effect can be either positive or negative.
4. Positive stack effect is the upward movement of air in a vertical shaft. Negative stack effect is the downward movement of air in a vertical shaft.
5. Positive stack effect decreases as the outside air temperature decreases in relation to the temperature inside the building.
6. Negative stack effect may occur when the outside temperature is lower than the temperature inside the building. Its possibility is least likely when the outside air temperature is above 90o.
7. Both positive and negative stack effect may be intensified by the speed and direction of the wind.
8. To obtain the greatest benefit from the stack effect, the doors at the top and bottom of the stairway must be opened when a stairway is used for smoke removal. The street floor near this stairway must be closed.
A) 1,2,3,4,7,8 B) 1,2,3,4,7 C) 1,3,4,5,7,8 D) 1,2,4,6,7
- B
Natural vertical ventilation is influenced by the stack effect as follows:
- Its effect becomes noticeable in buildings over 60 feet, and increases as the building’s height increases.
- Its effect can be either positive or negative.
a. The positive stack effect is the upward movement of air in a vertical shaft.
b. The negative stack effect is the downward movement of air in a vertical shaft. - Positive stack effect increases as the outside air temperature decreases in relation to the temperature inside the building.
- Negative stack effect may occur when the outside temperature is greater than the temperature inside the building. Its possibility is greatest when the outside air temperature is above 90o F.
- Its effect, both positive and negative, may be intensified by the speed and direction of the wind.
- To obtain the greatest benefit from the stack effect, the doors at the top and bottom of the stairway must be opened when a stairway is used for smoke removal. The street floor near this stairway must also be vented to the outer air.
20) BC Question - Two BCs discussing the Department’s “HVAC Strategic Operating Plan” for high-rise buildings would know which statement below to be incorrect? (HR 3.3.1, 3.3.4, 3.3.5)
