Determine whether glazing in and adjacent to a commercial entrance door requires safety glazing under the IBC, and confirm the identification mark it must bear.

Steps

1. On codes.iccsafe.org, open IBC Chapter 24, Section 2406.4.1 'Glazing in doors' — all fixed and operable panels of swinging, sliding, and bifold doors are hazardous locations with no area exception
2. Open Section 2406.4.2 'Glazing adjacent to doors' — a fixed or operable panel next to a door is hazardous if its nearest vertical edge is within a 24-inch arc of the door's vertical edge (door closed) AND its bottom edge is less than 60 in. above the walking surface
3. Verify Section 2406.3 identification requirements: designation must be acid-etched, sandblasted, ceramic-fired, laser-etched, or embossed (or a permanent label), stating who applied it and which safety glazing standard (e.g., ANSI Z97.1 or CPSC 16 CFR 1201) it meets
4. Check the 2406.3 exceptions — non-tempered glass may rely on a builder's certificate/affidavit instead of an etched mark if the building official approves, and tempered spandrel glass may use a removable paper designation
5. Note that Section 2403.1 information (manufacturer, glass type) must also travel with the designation per the 2406.3 cross-reference
