Which document serves as the primary reference for verifying that a firestop installation matches the approved listed system?
Answer: The UL or FM system drawing (e.g., UL System Card)
UL system cards (or equivalent FM/ICC-ES documentation) define the exact materials, configurations, and dimensions required for a listed firestop assembly.
During a QC inspection, an inspector finds that the annular space around a pipe penetration exceeds the maximum allowed by the listed system. What is the correct action?
Answer: Document the non-conformance and require corrective action before approval
Any deviation from listed system parameters must be documented as a non-conformance; the installation must be corrected to match the listed system before it can be accepted.
What does the term 'special inspection' mean in the context of firestop systems under IBC?
Answer: An inspection by a qualified inspector to verify code-required work during and after installation
Under IBC Chapter 17, special inspection is continuous or periodic inspection by a qualified inspector to ensure structural and fire-resistance systems are installed per approved documents.
When inspecting a head-of-wall joint firestop system, which dimension is most critical to verify against the listed system?
Answer: The maximum joint width and allowable movement
Head-of-wall systems are listed for specific maximum joint widths and movement ratings; exceeding these invalidates the fire rating.
A Quality Control Plan (QCP) for firestop work should be submitted to the authority having jurisdiction (AHJ) at which project phase?
Answer: Before firestop installation begins
The QCP must be reviewed and approved by the AHJ before installation starts to ensure all materials, methods, and inspection protocols are pre-authorized.
Which ASTM standard governs the installation and quality inspection of through-penetration firestop systems?
Answer: ASTM E2393
ASTM E2393 is the Standard Practice for On-Site Inspection of Installed Fire Resistive Joint Systems and Perimeter Fire Barriers.
What information must be captured in a firestop inspection report for each penetration or joint?
Answer: Location, listing system used, material lot numbers, and pass/fail status
Comprehensive inspection records must include the location identifier, the specific listed system reference, product lot/batch data for traceability, and the inspection outcome.
