Frequently Asked Questions (FAQ) Regarding Fire-Rated Access Panels for High-Risk Commercial Buildings

1. What fire-resistance rating is required for access panels in commercial buildings?
Fire-rated access assemblies must match the fire-resistance rating of the surrounding wall or ceiling assembly. Common ratings include 1-hour, 1.5-hour, and 2-hour, depending on occupancy type, location within the building, and fire compartmentalization strategy.

2. Which areas in a commercial building require fire-rated access panels?
Fire-rated access panels are particularly critical at locations integral to the building’s fire containment and egress strategy. These include:

• Stairwells

• Fire-rated corridors

• Mechanical and electrical chases

• Shaft enclosures

• Rated ceiling assemblies

3. What documentation and approvals are required for fire-rated access panels?
Submittals should include:

• Third-party fire test certification (e.g., UL, Intertek)

• Manufacturer’s cut sheet

• Rated assembly details

• Installation instructions

4. How do fire-rated access panels reduce inspection approval risks and long-term liability?
To mitigate inspection risks, fire-rated access panels should match specified assemblies, comply with code requirements, and be supported by verifiable documentation. This also helps minimize long-term liability by reducing the time spent on rework and project delays.
