You're confusing an "Area of Refuge" with the horizontal exit's "refuge area." These are two completely different things.cda said:
“continuous and unobstructed way of egress travel from any point in a building or facility that provides an accessible route to an area of refuge, a horizontal exit or a public way.”
[BE] AREA OF REFUGE. An area where persons unable to use stairways can remain temporarily to await instructions or assistance during emergency evacuation.
Horizontal Exit Refuge Area
The fire wall is to create a separate building. The existing building is too large for an addition. Just because a two hour wall is in place,,,, Does not always mean it is a horizontal exit
