Stairway obstruction

[cda]

Am I dreaming again, or were "fire standpipes" allowed to occupy some of the width in a stairway?

905.4

The key is they are out of the radius of the required width

Aside from poor design; are there violations? The handle projects about 2-inches over the red line.

Background information; this is not an accessible route. The outer red line is the edge of the radius (ignore the inside line), it appears oval from the viewpoint.

appears compliant to 1003.3 & 1003.6 as the handle is only 2" projection into width.
