We installed 1-1/4" to 1-1/2" EMT conduit within the wall, extending down to the floor below. This conduit will serve as a chase for data cabling connected to poke-through floor boxes, with both ends stubbing out from the wall above and the floor below.
Is there a fire-stopping detail available or an EJ alternative that illustrates the application of fire sealant around the EMT conduit and the opening in the 1-hour rated concrete slab? Additionally, sealant inside the EMT conduit where the data wires will be routed.
Please note that the concrete slab is 9" thick and classified as a 1-hour rated assembly, while the wall above is not rated. There is already 5/8" of FS-ONE Max sealant in the core around EMT inside the wall cavity.
Hi Justin we would need to look at this in an EJ. Please see below for how to submit an EJ.
Thank you,
