We have just had a safety screen explode, sending toughened glass flying some 15 feet.
I asked for the service engineer to attend site asap (these peopl are the market leaders in commercial swing and sliding doors) and have maintained the doors since installation some 4 years ago.
The safety screen is full length and protects people from being trapped by the door.
The safety screen, can be opened for cleaning on the inside by sliding up a pin, which allows it to open on hinges for access to the back of the screen.
When found the screen had been laying against agains a pillar some 18" away, the top hinge had parted from its base, the bottom hinge is assumed to be still in it's base.
A staff member was sent to check it out, and levered it forwards, to see if the bottom pin was in place, then as he was laying it back onto the pillar, it exploded.
He had quite afew minor cuts to arms and top of his head.
Has anyone had a similar experience?
I believe this safety screen was toughened glass but not laminated, as i would have expected it to remain in mainly on piece, and not over a 15 foot radius.

Although approx. 5 or 6 times stronger than annealed glass, Toughened glass can "explode" with some force when it does break. Could be that the glass was flexed too much which caused this and the glass particles could travel 15'. Makes a heck of a noise too and Toughened glass can shatter without any apparent external forces applied to it / objects hitting it, although this is quite rare.
