IBC 2406.4.6? Hazardous glazing.

[steveray]

2406.4.6 Glazing adjacent to stairways and ramps.
Glazing where the bottom exposed edge of the glazing is
less than 60 inches (1524 mm) above the plane of the adjacent
walking surface of stairways, landings between
flights of stairs and ramps shall be considered a hazardous
location.

I believe in 2012 the red portion was added, anyone know why? seems weird on an oversized landing that you seem to get "penalized"...But maybe there was some evidence to back it up...?....TBZ?

Thanks!

Safety Glazing - A Quick Reference Guide

In an effort to save me (and hopefully you) time in the future, I have compiled a quick reference guide for safety glazing. All references are to the 2015 IBC.

Safety Glazing at Ramps

Do you "infer" the requirements for ramps to be the same as stairs from the exception one (1) to 2406.4.6? 2406.4.6 & 2406.4.7 my reading requires safety glazing at landings between ramps and stairs but not at the ramp slope and landings at the top and bottom of ramps. If it were not for...

The 2012 IBC revised nearly all of Section 2406 by converting the previous list of hazardous locations into individual sections.

The list of items in the 2009 IBC included stairways for this hazardous location, but the entire paragraph was rewritten, so that portion you highlighted in red was not really added; it was just rearranged.

I assume you are questioning this because the definition for a stairway includes the landings, which has not changed since the first IBC in 2000. I cannot be sure, but I think it is a carryover from the three model codes' transition to the IBC. In the UBC, there was no definition for a stairway, so the description of the hazardous location needed to include "landings" specifically, or it could have been interpreted that only the stair portion was subject to the hazardous location requirements.

When the IBC came onto the scene, the stairway definition was added, but the description of the hazardous location, including the use of "landings," lived on in pretty much the same form as it always had. However, nobody bothered to refine the requirement, probably because it would cause more confusion if it were removed than if it were left in.

Thanks Ron....I guess it used to be interpreted as "required" landings, but I believe that has been clarified for better or worse.....
