It breaks into sharp shards. In this article, e2571 and premises safety expert, Anthony Shinsky discusses various aspects of flooring that influence pedestrian safety.
The glass in glass elevator car doors shall be not less than 60 percent of the total visible door panel surface area as seen from the car side of the doors. First produced in Europe, wired glass was introduced to the United States in or around Glass installed in hoistways and hoistway doors where the hoistway is required to have a fire-resistance rating shall also comply with Section Shower and sauna enclosures and glass enclosures at some recreational and sports areas are also identified as impact hazard areas.

His discussion covers the various categories of glass, the use of glass in windows, doors, and partitions, and relevant safety standards. While not as strong as the later developed annealed or tempered glass, wired glass was used for over 50 years in windows in doors and along corridors, and those areas required to provide fire separation protection.

One side can shatter from impact without the other side shattering, and, when the glass shatters, it does not delaminate into shards… Tempered Glass is created during manufacture by rapidly cooling the outer surfaces of the glass while the inner portion remains viscous. Heat Strengthened Glass H. Glass ast, annealed glass that goes through a heating and cooling process designed to double its strength in comparison to ordinary annealed glass.
Glass in elevator hoistway enclosures and hoistway doors shall zstm laminated glass conforming to ANSI Z As the injured person recoils, the pointed shards can make deep lacerations that can be life threatening.
Float glass was the most common type of glass used in buildings until recent times.
