2. Which NYC Building Code section specifically addresses fire-resistant
penetrations and joints special inspections?
• A. BC 1704.25
• B. BC 1704.26
• C. BC 1704.27
• D. BC 1704.28

Systems. This section requires special inspections for through-
penetrations, membrane penetration firestops, fire-resistant joint
systems, and perimeter fire barrier systems.
3. Which NYC regulation establishes the qualification requirements for
special inspectors?
• A. 1 RCNY §101-01
• B. 1 RCNY §101-06
• C. 1 RCNY §101-07
• D. 1 RCNY §101-08
Answer: B. 1 RCNY §101-06
Rationale: 1 RCNY §101-06 establishes the structure and registration
requirements for special inspection agencies and the qualification
requirements for the special inspectors they employ.
4. Which ASTM standard governs the on-site inspection of installed
penetration firestop systems?
• A. ASTM E119
• B. ASTM E2174
, Page 3 of 59
• C. ASTM E2393
• D. ASTM E814
Answer: B. ASTM E2174
Rationale: ASTM E2174 is the Standard Practice for On-Site Inspection of
Installed Fire Stops. It provides methods for field verification and
inspection of penetration firestop systems.
5. Which ASTM standard governs the on-site inspection of installed fire-
resistive joint systems and perimeter fire barriers?
• A. ASTM E119
• B. ASTM E2174
• C. ASTM E2393
• D. ASTM E814
Answer: C. ASTM E2393
Rationale: ASTM E2393 is the Standard Practice for On-Site Inspection of
Installed Fire Resistive Joint Systems and Perimeter Fire Barriers.
6. Firestopping special inspections must be performed by:
• A. Any licensed plumber
• B. A Special Inspector employed by an approved Special Inspection
Agency
• C. The general contractor's superintendent
• D. The building owner
Answer: B. A Special Inspector employed by an approved Special
Inspection Agency
Rationale: Firestopping is a special inspection item under the NYC
Building Code; only qualified Special Inspectors working under approved
agencies may perform and document these inspections.

7. What is the primary purpose of firestopping in building construction?
• A. Improve thermal insulation
• B. Enhance acoustic performance
• C. Maintain the fire-resistance rating of fire-rated assemblies
• D. Reduce energy costs
Answer: C. Maintain the fire-resistance rating of fire-rated assemblies
Rationale: Firestopping prevents the spread of fire and smoke through
penetrations and joints in fire-rated assemblies, maintaining the integrity
of fire-resistance-rated construction. This is a critical life-safety function.
8. The firestop inspector must be independent of which parties?
• A. The building owner only
• B. The architect only
• C. The installer, contractor, manufacturer, and supplier
• D. The special inspection agency
Answer: C. The installer, contractor, manufacturer, and supplier
Rationale: The firestop inspector needs to be completely independent of
and divested from the installer, contractor, manufacturer, or supplier to
avoid conflicts of interest.
9. Special inspections for firestopping are NOT required for building
components unless:
• A. The building is over 6 stories
• B. The design involves the practice of professional engineering or
architecture
• C. The building is residential
