discussing the strategic operating plan for HVAC systems, you would know as a seasoned Fire
Tech student that they were wrong in which talking point listed below? (High Rise
Office Bldgs, section 3.3)
A) First determine the status of all HVAC systems in the building. Any systems that have not
been automatically shut down shall be manually shut down. This shall include both the supply
and return fans.
B) Before any further action can be taken with the HVAC system, the fire floor must be
accurately determined.
C) All the HVAC systems shall be placed in the non-circulating mode by; opening all outside
air supply dampers, closing all mixing dampers, opening all exhaust dampers.
D) After the fire floor has been adequately determined, all HVAC zones shall have their
supply fans activated.
E) Whenever the HVAC systems are reactivated, all units operating in the building shall be
alerted to report any adverse effects.
- D
3.3.4 After the fire floor has been adequately determined, all HVAC zones that do not
include the fire area shall have their supply fans activated. This will supply
fresh outside air to these zones, pressurizing these zones and limiting the spread
of smoke. It will also supply fresh outside air to any occupants on the floors in
these zones.
6) Automatic closure of fire dampers is usually effected upon operation of an approved fusible
link or other approved heat activated device located where they would be readily effected by an
abnormal rise in temperature in the duct. Fusible links should have a temperature rating
approximately _______ degrees F above the maximum temperature that would normally be
encountered with the system in operation or shut down. Please fill in the blank? (High
Rise Office Bldgs, section 3.4.1)

C) It always has been the responsibility of building engineers to start the building fire pumps.
D) None of the above
- C
14) Occasionally our members might be forced to operate building fire pumps, if the engineer
is not present. Please choose from the list below an incorrect procedure when operating building
fire pumps? (High Rise Office Bldgs, section 4.4.2)
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 out). Some engineers keep them
open for test purposes, so they must be checked by the ECC assigned to operate the pumps. If
they are found to be open, they should be closed by turning in a counterclockwise direction.
C) Some systems are quite complex and the bypass valve is not readily discernible. If such a
situation is present, it is permissible to start pump as ordered without checking bypass valve.
Notify the engineer upon his/her arrival of this and any other actions taken.
D) The efficiency of the pump will be affected if the bypass is open. 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.

(High Rise Office Bldgs, section 4.4.8)
A) Building fire pumps are usually located in the cellar or sub-cellar and fire lines connected
to them should be painted red.
B) Pump capacity is usually 750 gpm. Most high-rise buildings have two pumps side by side
which are connected in the series position.
C) Some buildings have a combination standpipe/sprinkler system with the siamese connected
to both systems. The usual arrangement for the fire pumps is that one will be automatic and one
manual.
D) Automatic fire pumps may be of smaller capacity (250 gpm or 500 gpm).
- B
C. Pump capacity is usually 750 gpm. Most high-rise buildings have two
pumps side by side which are connected in the parallel position.

one should you correct before the firefighters question your accuracy? (High Rise
Office Bldgs, section 4.5)
A) The building fire pumps shall be capable of delivering their rated capacity at a pressure of
50 psi at the highest floor hose outlet.
B) A relief valve is required at the fire pump limiting the pressure to 15 psi above that required
to deliver its rated capacity at 50 psi to the highest floor outlet.
C) When the building fire pumps and Fire Department engines are being used to supply the
standpipe system, both systems must be monitored to prevent overheating caused by churning.
D) A good “rule of thumb” is to have a separate engine supply the standpipe system for every
two hand-lines in operation.

- The CFR engine company, with all CFR-D equipment and forcible entry
tools, shall be assigned to the Fire Sector Supervisor/Branch Director.
20) A prime decision that the Incident Commander must make at a High Rise office Building
fire is the placement of the first line. The following conditions must be considered: (High
Rise Office Bldgs, section 5.4.1)
A) A hose-line shall not be operated from a stairway until it has been cleared of building
occupants.
B) A stairway shall be selected for evacuation of building occupants (evacuation stairway)
preferably a fire tower if available.
C) The Fire Sector (fire floor and the floor above) are initially all that are required to be
evacuated.
D) Occupants of many other floors may self-initiate evacuation, utilizing any or all stairways
until instructed otherwise. This mandates that all stairways are searched, especially the
evacuation stairway before and during fire operations.
Please choose an incorrect condition from the list above?
- D
- The Fire Sector (fire floor and the floor above) are initially all that
are required to be evacuated. However, occupants of many other
floors may self-initiate evacuation, utilizing any or all stairways
until instructed otherwise. This mandates that all stairways are
searched, especially the attack stairway before and during fire
operations.
21) You are working in Engine 500 when you respond third due for a fire in a High Rise Office

Elevator banks A B C serve all floors
Upon your arrival you hear the first arriving ladder company confirm to the Incident Commander
that the fire is on floor number 22. You take the A elevator to floor number 18 and then proceed
to walk to the floor below the fire. The 2nd arriving BC has not arrived at the Fire Sector so you
communicate directly to the Incident Commander. The IC directs you to stretch the 2nd line to
the floor above, because the third due ladder is reporting that they have minor extension via a
flexible connector in the periphery air system. Do you agree or disagree with the placement of
the 2nd hand line? (High Rise Office Bldgs, section 5.4.3)
A) Agree or D) Disagree
