Which statement best describes patching around penetrations as required by spec?

• A. To improve aesthetics
• B. To maintain continuity of fireproofing around penetrations and document
• C. To reduce material costs
• D. To speed up surface preparation

Answer: (B)

Patching around penetrations is about preserving a continuous fire-resistant barrier where pipes, cables, or ducts interrupt the fireproofing, and about recording that work for verification. If penetrations aren’t properly patched, gaps can create paths for fire and smoke to bypass the rated protection, reducing the assembly’s fire resistance. The specification expects patches that restore the same fireproofing performance and that are documented so inspectors can confirm the rating remains intact. It’s not primarily about aesthetics, cutting costs, or speeding up prep.
