stair vignette-area of refuge and width or stairs

Postby spike » Fri Aug 11, 2017 12:27 pm

I was going through the program for the stairs vignette and came across this:
"When area of refuge are required, stairway width shall have a minimum clear width of 48" between hand rails."

Just making sure that I have understood this correctly..so
if the staircase width calculated as per capacity of exit component based on occupant load is LESS than 48" CLEAR and we have an area of refuge then min width of stairs would be
48"(stairs)
+4"(2 hand rails of 2")
+2"(1" on either side of hand rail)
=54" total?

thanks in advance

Hold rails 2" off walls and edges, so use 56" overall.
