Penetrations of floor/ceiling assemblies shall be protected in accordance with which code?

Penetrations of floor/ceiling assemblies shall be protected in accordance with which code?

• A. State Board of Architecture and Engineering
• B. Standard Structural Code
• C. Minnesota Fire Code
• D. Minnesota Building Code

Answer: (D)

Penetrations through floor and ceiling assemblies are governed by the Building Code because it covers how openings affect fire separation and what is required to preserve the assembly’s fire-resistance rating. When a pipe, duct, or conduit passes through a rated floor/ceiling, an approved firestop system or other listed protection must be used and installed according to the Building Code references. The Minnesota Building Code is the authoritative document for these construction details. The licensure board oversees professional practice, not how penetrations are protected; the Structural Code isn’t the source for this requirement, and while the Fire Code addresses fire safety, the requirement to protect penetrations as part of the building envelope falls under the Building Code.
