All fitted glass should be of concern to everyone especially here in Spain where the norm is 4mm thickness – even in doors. It is so easy to crash into these, particularly if marble or ceramics have been installed on floors.
Flying glass can result in serious injuries in the same way that physically falling through glass can.

Solar Guard's safety and security window films or normal window films can dramatically reduce the incidence of flying glass when breakage occurs. The film actually becomes a "bonded" part of the glass –  so the broken glass is held in place by the film in the event of a breakage, thus saving lives or preventing injury. Filmed windows can take up to 20 times longer to break through which in turn will protect your property and deter unwelcome visitors.
