breaking glass

Pane in pieces

Breaking glass is the sound or act of glass shattering, often signaling danger, intrusion, or emergency.

Security systems detect breaking glass as a trigger for alarms.

The phrase evokes sudden violence or accident—a window smashed, a bottle dropped.

Figuratively, it suggests crossing a threshold: break glass in case of emergency labels drastic measures held in reserve.
