Under IBC special inspection requirements, how frequently must a periodic inspector visit an active firestop installation?
Answer: Often enough to observe a representative sample of each type of system being installed
Periodic special inspection requires the inspector to observe a representative sample of each system type to confirm compliance; the exact frequency is defined in the approved inspection program.
Which condition would cause an inspector to reject a firestop sealant installation without requiring physical probing?
Answer: Visible voids, cracks, or incomplete fill visible on the exposed face of the assembly
Visible surface voids, cracks, or incomplete coverage are direct indicators of deficient installation that justify rejection on visual inspection alone.
What is the purpose of a 'firestop program' as referenced in the IBC?
Answer: To establish a documented process for design, installation, inspection, and documentation of firestop systems
A firestop program is a comprehensive, documented management system that covers the full lifecycle of firestop work — from design through final inspection and record-keeping.
When a non-conforming firestop installation has been corrected, what is required before the inspector closes out the non-conformance?
Answer: Re-inspection of the corrected work with documentation confirming it now meets listed system requirements
Non-conformances are formally closed only after re-inspection confirms the corrected installation matches the listed system and the finding is documented as resolved.
A firestop inspector discovers that a listed intumescent product was installed but has expired per its manufacturer-stated shelf life. What should the inspector do?
Answer: Reject the installation and require replacement with in-date material
Expired firestop materials may not perform as tested; the listing is only valid for materials within their stated shelf life, and the installation must be rejected.
Which entity is ultimately responsible for ensuring firestop special inspections are performed on a construction project?
Answer: The owner or owner's authorized agent
IBC Section 1705 places responsibility on the owner (or their authorized agent) to retain approved special inspection agencies and ensure inspections are conducted.
What does 'L-rating' measure in a firestop assembly, and why is it relevant to QC inspection?
Answer: Air leakage through the assembly at ambient and elevated temperatures
L-rating quantifies air leakage in cfm/ft²; inspectors must verify the correct L-rated system was used where code requires air barrier or smoke-leakage control.
