Mezzanine Help

Mezzanine Help

Mezzanine Help

Sorry if I double posted this.

I have a mezzanine with an at-grade exit as well as a curved open stair to the floor below. The floor below is also at grade and it has two exits that are too close to one another to meet remoteness requirements. Can I use my exit off my mezzanine as my second means of egress? The occupants will need to travel up the stair from the second floor to reach it, obviously. Travel distance is not a problem. Thoughts?

RE: Mezzanine Help

The at-grade exit and the curved open stair are two separate means of exiting the mezzanine. They are NOT one in the same.

RE: Mezzanine Help

What's the occupancy and the occupancy load? I don't think the IBC will allow you to use a spiral stair as a means of egress component.  

RE: Mezzanine Help

The stair is a winder stair that does meet NFPA requirements. However, I just noticed that IBC 1009.3.1 does not allow them for a means of egress. NFPA does allow them with some dimensional requirements.  

RE: Mezzanine Help

Okay, I was wrong. IBC does allow them through an exception. The occupancy load on the mezz. is 104 persons.

RE: Mezzanine Help

As long as the winder stair meets the egress requirements it can be used as an exit.  The winder stair would have to be included as part of the travel distance.  IBC chapter 5 contains a lot of the mezzanine requirements.
