Smoke vs fire protected

project planning & design

Hello,

What is the difference between a smoke protected egress stairway and a fire protected stairway?

Thank you

Smoke protection, which is covered in IBC chapters 709 and 710, are primarily used in healthcare and assembly occupancies to prevent the spread of smoke. There are smoke barriers and smoke partitions, each with their own requirements as set forth in the previously mentioned sections of the IBC.
Fire protection and ratings of stairways/hallways/between occupancies is covered throughout the rest of chapter 7, and is what you’ll predominantly deal with on the ARE and in practice, unless designing many healthcare and/or assembly occupancies.
