Heat strengthened and tempered glass break into rounded cubes which may still contain sharp edges, but do not form dagger-like shards. The use of wired glass has faded with the introduction of ceramic and tempered glass products but it is still present in many older buildings today.

These products are less likely to break when subjected to impact and less likely to cause serious injury if broken. 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.

This article was developed in concert with other members of the Premises Safety practice group. These shards can easily cut flesh and tendons, and the results can be severe or even deadly. This standard includes performance, design, and safe behavior considerations. Model codes, including the International Building Code, define these areas as those subject to human impact.

Depending upon where and how they are used, even these products can be hazardous. Shower and sauna enclosures and glass enclosures at some recreational and sports areas are also identified as impact hazard areas.
