Fire-proofing conduit
Fire-proofing conduit
(OP)
The conduit that supplies my client's fire pump controller with power runs through a room not protected by sprinklers. Is there a product that I can apply (foam, blanket, etc.) to this conduit to make it fire resistant, even fire proof. Re-routing the conduit is not an option.
Thanks...

I went thru this same situation about 10 years ago. Although the insurance inspectors were willing to let me get by with fireproofing and sheetrock (making the equivalent of a 2-hour enclosure around the conduit), the fellows from construction code enforcement were only willing to accept 4-hour construction as "equivalent protection" (i.e., still didn't meet code). We had to put 4" of concrete around it.
Good luck with your situation!

I forgot to mention that this conduit is running through the ceiling joists, about 10' above grade. Concrete doesn't seem like an option.

If the cable length is short it may be easier to replace it by a fire resistance/MI cable, otherwise you may use Endothermic Ceramic Fiber Blanket (manufactured by 3M), they claim that they have a standard design for 3-hour rated electrical system protection.
