Identification of Safety Glazing - ??? Laminated 2018-2406.3 NJ Addition

[tbz]

This might seem like an odd question but I will do my best.

Glass railing project within a 2-Story R2 Retirement complex.

Etched glass panels which pass light but not clear vision, Laminated so the etched tempered Labels are only visible from one side, not both sides.

Custom Glass company is asking us to verify with the AHJ if they want (2) labels, one on each tempered glass sheet that makes up the laminated glass panel, I am checking with the AHJ, but in the mean time I felt a need to drop this question on here.

The Custom Glass Panel manufacture informed me that some AHJ are requiring the label to be visible from both sides, can you all help me out here and explain to me the need for the label to be visible from both sides of a laminated etched panel?

It seems to me the label is only there to verify and hold someone liable for the panel if not made correctly, the being visible requirement of 2406.3 is so the Inspector does not have to hunt for it.

But if it is only visible from one side what's the big deal and how does the code section make it a requirement?

Humm had similar question a week ago

Guess it depends on if visible for inspection, from where accessible

Ask the door guru!!

Read some of the exceptions to the rule

What do you make of this bit of code: "or of a type that, once applied, cannot be removed without being destroyed"?

They want it to be there?? And if removal is tried, glass breaks or other along with the mark

I have always had the Labels ("Glass Bugs") set bottom corner closest to the lower side of the stair flight readable from the stair or balcony side.

For the upper level or Mezz the lower corner closest to the stairs if any or main access point.

Thus my reasoning is, the inspector is going to ascend up the stair flight being able to read the etching and continue along the journey till done.

As for the being visible from both sides, why??? are they going to climb a ladder to try and read the etching backwards?????

And where does it say visible from both sides in the code???

It doesn't...and what would they do if it were 40' in the air? (not that that would be likely to be tempered).....If they can prove it in some way I am good...Binoculars or zoom is a wonderful thing...

Check it before they fly it???

Drone inspections.....

 

[Mr. Inspector]

So terrorists flying plans into the building could see them.

Why not use heat-strengthened glass, which does not require a label. Then, when laminated, provide one label for the laminated unit.
