QA and Best Practice Manual Protocol

XXII. MEPF Penetrations & Firestopping

 It is preferred to have one contractor be responsible for all fire safing of required penetrations. This creates a single source and aids in coordination and control of the work preformed. And they are required to produce a General Certificate Of Conformance/Fire Penetration Affidavit. Costs involved, need to confirm with estimating.  All penetrations should be carefully detailed to prevent water from entering the structure. All exterior pipe/conduit penetrations need to be stucco and caulked prior to installation of fixture. Fixtures need to be caulked to stucco wall.

 CPVC pipe shall not be degraded by incompatible chemicals in fire caulk or antimicrobial coating in steel components.

 Acoustical sealant installed in a fire rated assembly must be fire rated.

 Identify packing material to be used at pipe penetrations. Provide UL Listing.

 Outlets for CATV, phone and electrical shall have 1/4-inch acoustic sealant around the box to the drywall per NEC 410.65.

 Outlets in dwelling unit separation walls shall have acoustical pads completely surrounding the box and wire holes.

 Provide details of wall assemblies that clearly indicate proper construction for wet areas at rated walls.

 Framing dimensions accommodate the required fire-rated gypsum board and clearances to the fixture.

 Rated gypsum board is installed fully behind the tub/shower with no gaps or breaks in the gypsum board.

 Provide a detail indicating that the washer box installed in a separation wall shall be boxed out with 5/8-inch type X gypsum board beforehand. Washer boxes are not rated for use in fire assemblies, and such penetrations are required to be protected.

 Verify that the location of fire-rated walls matches the location of smoke dampers on the mechanical drawings.

 All combustible materials exposed within the plenum space shall comply with UMC Section 602.2.

 Materials shall have a mold, humidity, and erosion resistant face that meet the requirement of UL 181.
