A fixed glass panel forms part of a shower enclosure. Its bottom exposed edge is 48 inches above the standing surface. Under 2021 IBC 2406.4.5, how is this glazing treated?

Correct Answer

B) It is glazing in a hazardous location requiring compliant safety glazing

The bottom edge is below the 60-inch threshold for shower-enclosure glazing. Fixed construction does not remove the hazard classification. The rule covers every pane in multiple glazing; the separate horizontal-distance exception does not establish a shower exemption. Source: 2021 IBC 2406.4.5.

Answer Options
A
Fixed glass is exempt from safety-glazing requirements
B
It is glazing in a hazardous location requiring compliant safety glazing
C
Ordinary annealed glass is sufficient solely because the panel is fixed
D
The hazardous-location rule applies only above 72 inches

Why This Is the Correct Answer

The bottom edge is below the 60-inch threshold for shower-enclosure glazing. Fixed construction does not remove the hazard classification. The rule covers every pane in multiple glazing; the separate horizontal-distance exception does not establish a shower exemption. Source: 2021 IBC 2406.4.5.
