Fire chase

[ccha9219]

I do know you cant penetrate a fire wall with pvc
but can you run parallel 'in' a fire chase as long as you don't pass thru?
Here is the thing. At the airport control tower there is a framed "chase" in the corner. both the plumber and I used this chase to get from floor to floor. My lightning protection also uses this chase, in pvc. The stupid part is the chase is open at the top and bottom on the print.The top floor has an acoustical ceiling the first floor has no lid (I maintain that it is not a fire "barrier' but a fire pipeline to the cab.)I'm being told I have to run all conduit in emt.
including Lightning protection .Idont have that much installed yet....
The plumber ran all of his in plastic, he's slightly nervous
The debate is still rageing at the GC's office

Re: Fire chase

Ccha9219, what is in your specs?

As far as PVC penetrating the shaft, it can be done using the proper assembly, this would probably take a collar and intrumescent putty.

Here is one assebly for a 1 or 2 hr wall

Call Hilti, 3m, or your local fastener supplier and tell them the shaft type (this can be found in the achitectural plan sheets) and what you need to do.

Of course you need to check the specs first as I said before.

The plumber may be up the creek.

Sorry, I was editing my post while you were posting, go back and try the link.

Notice that that particular assembly is Hilti and not for electrical, also note it would not apply to another manufacturer.

Re: Fire chase

Just a question. Would you not be better off as far as the down conductor for lightning protection not being installed in a raceway?
