QUESTIONS 1–150
Question 1
Under the current NYC Administrative Code classification framework, which work is
specifically associated with a Class C Master Fire Suppression Piping Contractor license?
,A. All fire suppression piping systems without limitation
B. Fire suppression systems covered by paragraph 1 only
C. Fire suppression systems covered by paragraph 3 of the fire suppression piping system
definition
D. Only sprinkler systems connected to domestic water
Correct Answer: C
Explanation: Class C authorization covers the systems identified in paragraph 3 of the fire
suppression piping system definition, including dry, liquid, or gaseous chemical
suppression and other fire-control systems.
Question 2
A contractor holding only a Class C license is asked to install a conventional sprinkler system
serving 100 sprinkler heads from a dedicated fire pump. What is the principal licensing
concern?
A. The contractor may perform the work because all sprinkler work is Class C work
B. The contractor's Class C license does not authorize that sprinkler work
C. The contractor may perform the work if the owner signs a waiver
D. The contractor may perform the work if an electrician supervises it
Correct Answer: B
Explanation: Class C authority is limited to the applicable paragraph 3 systems;
conventional sprinkler work outside that scope requires the appropriate license
classification.
Question 3
A Class C contractor is installing a gaseous extinguishing system. Which activity most clearly
falls within fire suppression piping work?
A. Installing building lighting
B. Installing portable fire extinguishers
C. Installing the suppression agent distribution piping
D. Installing unrelated domestic plumbing
Correct Answer: C
Explanation: Installation of piping associated with a qualifying fire suppression system is
fire suppression piping work, while electrical components assigned to electricians and
portable extinguishers are outside the definition.
Question 4
,A Class C licensee is asked to perform work outside the class of license held. Which is the
most defensible compliance response?
A. Perform the work if it is technically simple
B. Perform the work and obtain approval afterward
C. Decline or arrange for a properly licensed contractor to perform the work
D. Perform it under the owner's direct supervision
Correct Answer: C
Explanation: Technical competence does not expand the legal scope of a professional
license. Work must remain within the authorization of the applicable license.

A. Technical competency automatically authorizes all related work
B. A license establishes legally permitted scope; competency establishes ability to perform
work safely
C. A license is unnecessary when the contractor has insurance
D. Code compliance is optional when an engineer approves the design
Correct Answer: B
Explanation: Licensing and competency are related but distinct. A qualified professional
must both possess the required authorization and perform work competently.

generally must either be:
A. A general contractor or architect
B. A licensed Master Fire Suppression Piping Contractor or working under the required
direct and continuing supervision
C. A building owner
D. An FDNY inspector

B. Identify the scope conflict and obtain appropriate authorization before performing the
work
C. Remove the system from the drawings
D. Ask the installer to assume responsibility
Correct Answer: B
Explanation: Scope must be resolved before unauthorized work begins. Proceeding without
appropriate authorization creates regulatory and professional exposure.
