In the Life Safety Code, what is the term for openings in a fire wall that are allowed if protected?

• A. Fire wall openings
• B. Rated openings
• C. Protected openings
• D. Resistant openings

Answer: (C)

Openings in a fire wall are allowed only when they are protected by a fire-resistance-rated assembly. This protection means using listed fire doors or shutters with proper frames, hardware, and seals that automatically close or otherwise maintain the wall’s integrity, keeping fire and smoke from crossing the wall. The term used in the Life Safety Code for these permitted openings is protected openings, highlighting that the opening itself is acceptable only because it is safeguarded by the appropriate fire-rating and protective hardware. Other terms don’t reflect the official designation—the phrase protected openings specifically conveys that the opening has been provided with the necessary fire protection to preserve the wall’s fire separation.
