When a crack reaches the edge of the glass
Does a crack that runs all the way to the edge change how quickly the area should be kept clear, even if the pane is still sitting in place? I’m especially unsure whether the answer differs for a single pane versus insulated glass.
What signs, like shifting glass or loose pieces, mean people should stay back until a glazier can assess it? And what’s a sensible way to keep the area clear without touching or pressing on the pane?

A pane can still be in place and be unstable. Visible bowing, movement, or loose pieces are reasons to keep everyone out of the room and get a glazier to assess it promptly. Don’t try to steady the glass; close the door or block access from outside the room. Is the crack confined to one pane, or is there any visible movement or loose glass?
An edge-reaching crack doesn’t by itself show whether the glass is stable. Visible bowing, movement, or loose pieces are reasons to keep people back and have a glazier assess it. For insulated glass, a crack in one lite doesn’t establish that the other is intact or that the unit is secure. Keep the area clear without touching or pressing on the pane.
