SECTION 1: FDNY RULES, REGULATIONS & CODES Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 42-year-old fire safety director at a midtown Manhattan high-rise receives a complaint
from a tenant on the 34th floor about a blocked exit door in a storage room. Upon
inspection, he finds the door wedged open with boxes and a chain lock has been
installed by building maintenance. Under FDNY regulations, which violation has
occurred?
A. A minor housekeeping issue with no regulatory consequence
B. An obstruction of a required means of egress ✓ CORRECT
C. A permitted temporary modification during business hours
D. A Class C violation subject only to a warning notice
Correct Answer: B
Rationale: Blocking or locking a required means of egress is a serious fire code violation
under FDNY rules because it prevents occupants from exiting safely during an
emergency and impedes firefighter access. A chain lock on an exit door is never
,permitted under any circumstances, and this constitutes more than a minor
housekeeping issue. Fire safety directors must document and correct such violations
immediately, as they expose the building to significant liability and endanger lives.
Question 2 of 50
A 35-year-old certificate of fitness holder is conducting a routine inspection of a
commercial kitchen in Queens. She notices that the kitchen's automatic fire suppression
system was last serviced 18 months ago according to the inspection tag. The kitchen
manager claims the system was tested informally by his staff last month. What must
the certificate holder do?
A. Accept the manager's verbal assurance and document it in her report
B. Issue a violation notice because the system requires servicing by a licensed
contractor every 6 months ✓ CORRECT
C. Allow the kitchen to operate with a warning to schedule service within 30 days
D. Test the system herself using the manual pull station to verify functionality
Correct Answer: B
Rationale: FDNY regulations require that commercial kitchen fire suppression systems
be inspected, tested, and serviced by a licensed contractor at intervals not exceeding 6
months, and informal testing by kitchen staff does not satisfy this legal requirement.
Verbal assurances carry no regulatory weight, and a certificate holder lacks the
authority to personally test or certify suppression systems. The 6-month service interval
ensures that nozzles, fusible links, and agent cylinders remain in proper working order
under the harsh conditions of a commercial kitchen environment.
Question 3 of 50
A 51-year-old building owner in Brooklyn is installing a new standpipe system in a
12-story residential building under construction. The fire protection contractor asks
,whether the standpipe outlets must be equipped with specific valve types per FDNY
code. Which valve requirement applies?
A. Gate valves with rising stems are required at all standpipe outlets
B. 2.5-inch hose valve outlets with pressure-regulating devices if static pressure
exceeds 100 psi ✓ CORRECT
C. 1.5-inch garden hose threads are acceptable for all residential standpipes
D. Ball valves with quick-connect fittings are the standard for all FDNY standpipes
Correct Answer: B
Rationale: FDNY code requires that standpipe hose valve outlets be 2.5-inch National
Standard Thread, and pressure-regulating devices must be installed when static
pressure at the outlet exceeds 100 psi to prevent injury to firefighters and damage to
equipment. Garden hose threads and ball valves with quick-connect fittings are not
compliant with FDNY standpipe standards. Building owners who fail to install proper
pressure regulation may face system rejection during final inspection and significant
delays in certificate of occupancy approval.
Question 4 of 50
A 29-year-old fire guard conducting his rounds in a Times Square hotel at 2:00 AM
discovers a small fire in a linen storage closet on the 8th floor. He activates the nearest
fire alarm pull station and calls 911. According to FDNY fire guard protocol, what is his
next required action?
A. Immediately attempt to extinguish the fire using any available means
B. Notify the fire safety director and begin evacuating guests from the affected floor ✓
CORRECT
C. Return to the fire command station and wait for FDNY arrival
D. Close all doors on the floor and return to his assigned post
Correct Answer: B
, Rationale: After activating the alarm and calling 911, the fire guard must notify the fire
safety director and initiate evacuation procedures for the affected floor in accordance
with the building's fire safety and evacuation plan. Attempting to fight the fire is only
appropriate if the fire is small, the guard is trained, and an extinguisher is readily
available. Fire guards who abandon their duties or fail to communicate with the fire
safety director create dangerous gaps in emergency response coordination.
Question 5 of 50
A 47-year-old property manager is reviewing the FDNY requirements for a newly
acquired Class E office building in the Bronx. He needs to determine how many fire drills
are required annually. What is the minimum number of fire drills that must be
conducted?
A. One fire drill every two years
B. Two fire drills per year, spaced at least 6 months apart ✓ CORRECT
C. Four fire drills per year, one per quarter
D. Fire drills are only required for buildings with more than 100 occupants
Correct Answer: B
Rationale: Class E buildings must conduct a minimum of two fire drills annually, with at
least one drill during non-business hours, and the drills must be spaced no less than 6
months apart to ensure all occupants remain familiar with evacuation procedures. One
drill every two years is insufficient for occupant preparedness, and quarterly drills
exceed the minimum requirement but are not mandated. Property managers must
maintain drill logs for FDNY inspection and document any deficiencies identified during
each exercise.
Question 6 of 50
A 38-year-old S-12 certificate holder is inspecting a warehouse in Staten Island that
stores aerosol products. She notices that the sprinkler system is designed for ordinary
