Section 2409 Glass in Walkways, Elevator Hoistways and Elevator Cars
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.

First produced in Europe, wired glass was introduced to the United States in or around ASTM E, Standard Practice for Design and Performance of Supported Glass Walkwaysprovides requirements for structural performance, markings for clarity and slip resistance for the design and construction of these features. Glass in elevator cars aztm be in accordance with this section. As the injured person recoils, the pointed asrm can make deep lacerations that can be life threatening. Glass in elevator hoistway enclosures and hoistway doors shall be laminated glass conforming to ANSI Z Without appropriate markings, people can unintentionally walk into these features and become injured without breaking the glass.

Impact resistance, breakage tolerance, deflection of the system, and the free area between components are all regulated by this standard and the failure to meet any one of them can result in injury. 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.
An allowable stress reduction factor of 0. Transparent glass walls where the glass cannot be easily distinguished from the surroundings should be made conspicuous to prevent impact injuries.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The glass is not subjected to further treatment such as sandblasting; etching; heat treatment or painting that could alter the original properties of the glass.
