elevator opening in a 2hr FRR firewall

[bso]

has anyone come across a situation as the title suggests? elevator door, for highrise for instance, typically comes with a fire separation of 2hr FRR. but can it be located in a firewall? there are a whole bunch of additional requirements such as smoke migration, and i cannot get an answer out of a the elvator guys. and there is no room to either side to add a vestibule.

cheers

I don't think it is possible unless another door is provided over the opening, since elevator doors cannot pass the smoke control requirements for opening protectives.

Another option is to make the side and back walls of the elevator shaft part of the fire wall and not use the wall with the openings. These walls probably extend above the roof anyway for the overrun or machine room, so why not take advantage of that?

Welcome

Is this real life or just a question??

If real life, why is the 2 hr wall there??

 

[Coug Dad]

welcome. Is this a fire barrier, fire wall, or what? Is it a horizontal exit? It makes a difference for when smoke resistance is required.

 

[RLGA]

The OP said it was a fire wall.

Ok sounds like the shaft is two hour, but why is the other two hour rated wall there???

The code offers multiple exceptions to provide a smoke seal across elevator doors without requiring a lobby.

The traditional application for an elevator is not to penetrate a fire wall..... I hope the original poster is correct in that this is a true fire wall and not a fire barrier or fire partition.

bso - Can the elevator face the other way and use the existing firewall as an hortizontal exit?
