SECTION ONE: QUESTIONS 1 – 50

B. Investigate the cause of the alarm to determine if it is a false alarm.
C. Implement the building's Fire Safety Plan and assume command of the
emergency response until the FDNY arrives.
D. Contact the building's maintenance department to shut off all HVAC systems.
🟢 Correct Answer: C. Implement the building's Fire Safety Plan and assume
command of the emergency response until the FDNY arrives.
🔴 Explanation: The Fire Safety Director's primary role is to take charge,
implement the pre-established Fire Safety Plan, and direct the response. This
includes coordinating staff, initiating communication, and managing the situation
until the FDNY arrives and assumes command, as per Section 401 of the NYC Fire
Code.
2. According to the NYC Fire Code, how often must a full fire drill be conducted in
a commercial office building classified as a "Place of Public Assembly"?
A. Monthly
B. Quarterly
C. Semi-annually
D. Annually
🟢 Correct Answer: B. Quarterly
🔴 Explanation: The New York City Fire Code mandates that full fire drills for
places of public assembly be conducted at least quarterly (every three months).
,This frequency ensures that occupants and staff are adequately prepared for an
emergency.
3. An activated sprinkler flow switch indicates water is moving through the
system. What is the most critical immediate action for the Fire Safety Director?
A. Reset the fire alarm control panel.
B. Dispatch a security guard to the approximate location of the flow switch
activation.
C. Announce a "sprinkler malfunction" over the PA system.
D. Notify the building's insurance company.
🟢 Correct Answer: B. Dispatch a security guard to the approximate location of
the flow switch activation.
🔴 Explanation: The flow switch indicates water is flowing from a sprinkler head.

inspect the area to confirm a fire or a broken pipe. This is the first step in
confirming the nature of the alarm before initiating other protocols.

Station"?
A. Elevator recall controls.

🔴 Explanation: The Fire Command Station (FCS) is the central hub for emergency
management. It must contain the public address and intercom systems, the status
of all fire protection systems (alarms, sprinklers), and communication links to the
FDNY. Elevator recall control is a function tied to the fire alarm system but is not a
component within the FCS itself.

materials in a stairwell. What is the correct action to take?

the authority and responsibility to order their immediate removal and is required
to report the violation to the fire department. This is a direct violation of the Fire
Code.
