,Q1. During a high-rise fire incident, a dispatcher receives multiple 911 calls reporting flames visible from the
30th floor of a commercial building. Using the FDNY High-Rise Fire Response Protocol, which of the
following actions should the dispatcher prioritize to ensure effective incident command and resource
allocation?
A. Immediately dispatch all available ladder companies to the reported floor without waiting for additional
information.
B. Initiate a staged response by sending a single engine company to investigate while holding other units at a
nearby staging area.
C. Assign the incident a '10-75' signal and dispatch a full first-alarm assignment including special units (e.g.,
tower ladder, rescue company) while establishing a command channel.
D. Advise callers to evacuate immediately and instruct all responding units to proceed to the lobby for
face-to-face briefing with building management.
Correct Answer: C. Assign the incident a '10-75' signal and dispatch a full first-alarm assignment including
special units (e.g., tower ladder, rescue company) while establishing a command channel.
Rationale: The correct action is to assign a '10-75' (working fire) signal, which triggers a full first-alarm
assignment with specialized units. This ensures a robust initial response and establishes a command channel for
coordination, per FDNY high-rise protocols. Option A is premature and risks insufficient resources; B is
appropriate only for low-risk incidents; D delays tactical deployment and bypasses command structure.
Why Wrong:
A - Dispatching all available units without assessment can deplete resources and cause congestion; a staged
response is more appropriate.
B - A single engine company is insufficient for a confirmed high-rise fire; a full assignment is required per
protocol.
D - Directing units to the lobby for briefing delays tactical operations; command should be established via
radio.
Reference: FDNY Fire Alarm Dispatcher Z-51 Manual, Chapter 4: High-Rise Fire Operations, 2026 Edition.
Q2. A dispatcher receives a fire alarm signal from a protected premises that shows a 'Supervisory Signal'
(Type 2) on the CAD. The building is a large warehouse with sprinkler system monitoring. According to
NFPA 72 and FDNY protocols, which of the following is the most appropriate initial response?
A. Dispatch a full structural fire assignment immediately, as supervisory signals indicate a potential fire
condition.
B. Treat the signal as a non-emergency and notify the building owner via automated system without
dispatching any units.
C. Dispatch a single engine company to investigate, as supervisory signals often indicate a system impairment
(e.g., valve closure) that could compromise fire protection.
D. Ignore the signal if it is during business hours, assuming it is a false alarm due to maintenance.
Correct Answer: C. Dispatch a single engine company to investigate, as supervisory signals often indicate a
system impairment (e.g., valve closure) that could compromise fire protection.
Rationale: Supervisory signals (Type 2) indicate conditions that could impair fire protection systems, such as a
closed valve or low water pressure. FDNY protocols require dispatch of a single engine company to investigate and
restore the system. Option A is incorrect because supervisory signals are not fire alarms; B is incorrect because the
signal requires human verification; D is negligent.
Why Wrong:
A - Supervisory signals do not indicate a fire; dispatching a full assignment would waste resources.
B - Automated notification is insufficient; a physical response is mandated to ensure system integrity.
D - Ignoring any alarm signal violates FDNY policy and could lead to catastrophic failure of fire protection.

SOPs.

, Q3. A dispatcher is handling a multi-casualty incident (MCI) involving a building collapse. Using the FDNY
MCI protocol and the Hospital Emergency Preparedness and Response (HEPR) system, which of the
following actions is critical for effective resource management and patient tracking?
A. Instruct all responding EMS units to transport patients to the nearest hospital regardless of capacity.
B. Assign a Medical Branch Director and establish a Medical Communications Center (MedComm) to
coordinate hospital diversions and patient distribution.
C. Request mutual aid from neighboring jurisdictions without first establishing a staging area.
D. Direct all patients to be triaged and treated on-scene without transport until all victims are extricated.
Correct Answer: B. Assign a Medical Branch Director and establish a Medical Communications Center
(MedComm) to coordinate hospital diversions and patient distribution.
Rationale: In an MCI, establishing a Medical Branch Director and MedComm ensures coordinated patient
distribution and hospital capacity management, preventing overwhelming any single facility. Option A can cause
hospital saturation; C is premature without staging; D delays definitive care for critically injured patients.
Why Wrong:
A - Transporting to the nearest hospital without coordination can overwhelm emergency departments and
hinder care.
C - Mutual aid should be requested after initial resource assessment and staging to avoid chaos.
D - Delaying transport for extrication violates the 'load and go' principle for critical patients.
Reference: FDNY MCI Protocol Manual, 2026; NYC HEPR System Guidelines.
Q4. A dispatcher receives a 911 call reporting a person experiencing a severe allergic reaction with difficulty
breathing and swelling of the tongue. According to the FDNY Emergency Medical Dispatch (EMD) protocol,
which of the following is the highest priority instruction the dispatcher should provide to the caller while
awaiting EMS arrival?
A. Instruct the caller to administer diphenhydramine (Benadryl) if available and monitor the patient's breathing.
B. Advise the caller to have the patient lie flat and elevate the legs to improve circulation.
C. Direct the caller to check for an epinephrine auto-injector and assist the patient in administering it if
prescribed, then begin CPR if the patient becomes unresponsive.
D. Tell the caller to induce vomiting if the patient has ingested a potential allergen.
Correct Answer: C. Direct the caller to check for an epinephrine auto-injector and assist the patient in
administering it if prescribed, then begin CPR if the patient becomes unresponsive.
Rationale: For anaphylaxis with severe respiratory distress, the priority is administration of epinephrine, which is
the first-line treatment. The dispatcher should guide the caller to use an auto-injector if available, and be prepared
for CPR if the patient deteriorates. Option A is incorrect because diphenhydramine is not first-line for severe
anaphylaxis; B is inappropriate as lying flat may worsen breathing; D is dangerous as it does not address airway
compromise.
Why Wrong:
A - Diphenhydramine is too slow for severe anaphylaxis; epinephrine is required immediately.
B - Lying flat can worsen respiratory distress; the patient should sit upright if possible.
D - Inducing vomiting does not treat airway swelling and risks aspiration.
