,Q1. In a high-rise building with a Class E fire alarm system, a fire is reported on the
15th floor. The fire alarm control panel indicates activation of a smoke detector on the
14th floor. Which of the following best describes the expected operational sequence of
the building's fire safety systems?
A. The HVAC system shuts down, all elevators return to the lobby, and stairwell
pressurization fans activate on all floors.
B. The HVAC system on the fire floor and adjacent floors shuts down, elevators are
recalled to the lobby or an alternate floor, and stairwell pressurization activates only on
the fire floor.
C. The HVAC system continues to operate to exhaust smoke, elevators remain in
service for fire department use, and stairwell pressurization is not activated until fire
department arrival.
D. The HVAC system shuts down only on the fire floor, elevators are recalled to the
floor below the fire, and stairwell pressurization activates on all floors below the fire.
Correct Answer: B. The HVAC system on the fire floor and adjacent floors shuts
down, elevators are recalled to the lobby or an alternate floor, and stairwell
pressurization activates only on the fire floor.
Rationale: In a Class E system, upon alarm, the HVAC system is typically shut down on
the fire floor and the floors immediately above and below to prevent smoke spread.
Elevators are recalled to the lobby or an alternate floor to prevent occupants from being
trapped. Stairwell pressurization is designed to activate on the fire floor to keep smoke out
of the stairwell, allowing safe egress. Option A is too broad (all floors), C is incorrect
because HVAC does not continue to operate, and D is incorrect because elevators are not
recalled to the floor below the fire.
Why Wrong:
A - This overstates the HVAC shutdown and pressurization scope, which are typically
limited to the fire floor and adjacent floors, not all floors.
C - HVAC systems are designed to shut down to prevent smoke recirculation, not
continue operation for smoke exhaust.
D - Elevators are recalled to the lobby or an alternate floor, not specifically the floor
below the fire, and stairwell pressurization is not limited to floors below the fire.

Q2. A fire occurs in a storage room containing Class A combustibles and a small
quantity of flammable liquids. The fire department arrives and initially applies a
stream of water. Which of the following is the most significant hazard associated with
using water on this fire?
A. Water can cause the flammable liquids to spread and increase the fire area.
B. Water may react with the combustibles to produce toxic gases.
Page 3
, C. Water can conduct electricity if it comes into contact with live electrical equipment.
D. Water may cause the fire to intensify by providing oxygen.
Correct Answer: A. Water can cause the flammable liquids to spread and increase the
fire area.
Rationale: Water is ineffective on flammable liquid fires because it does not mix with the
liquid and can cause the burning liquid to spread, enlarging the fire. While water can be a
conductor if it contacts electrical sources, the primary hazard in this scenario is the
spreading of flammable liquids. Water does not typically react with Class A combustibles
to produce toxic gases, and it does not provide oxygen to the fire.
Why Wrong:
B - Water does not generally react with ordinary combustibles to produce toxic gases
in this scenario.
C - Electrical hazards are a concern if water contacts live wires, but the presence of
flammable liquids poses a greater immediate hazard.
D - Water does not provide oxygen; it acts as a coolant and smothers the fire.

Q3. A building's fire pump is rated at 500 GPM at a pressure of 100 psi. The fire
department connection (FDC) is being used to supplement the building's water
supply. According to FDNY regulations, what is the primary purpose of the FDC?
A. To allow fire department apparatus to pump water into the building's standpipe or
sprinkler system.
B. To provide a direct water supply to fire department hoses for manual firefighting.
C. To enable building occupants to connect hoses for initial firefighting.
D. To allow the building's fire pump to be tested by the fire department.
Correct Answer: A. To allow fire department apparatus to pump water into the
building's standpipe or sprinkler system.
Rationale: The FDC is a critical interface that allows fire department pumpers to supply
additional water to the building's automatic fire suppression systems, such as standpipes
and sprinklers. This enhances the building's internal water supply, especially in high-rise
fires where municipal water pressure may be insufficient. It is not intended for direct hose
attachment by firefighters or occupants, nor is it primarily for testing the fire pump.
Why Wrong:
B - Firefighters connect hoses to standpipe outlets inside the building, not directly to
the FDC.
C - Occupants do not use the FDC; it is for fire department use only.
D - Fire pump testing is done via specific test headers, not the FDC.
