I was wondering if someone could help me understand Section 184.108.40.206 subsection 2.b within the NFPA 101: Life Safety Code.
The code reads, "A vertical extension is provided below the projection such that the extension has a leading edge that is within 4 in. (100 mm) of the leading edge of the projection at a point that is 27 in. (685 mm) maximum above the floor."
I am having trouble visualizing this point. What exactly do they mean by the leading edge? Is there a diagram available by any chance?
