Laminated glass products may break, but are held together by an interlayer of plastic or polymer reducing the asgm of exposure to sharp edges. As a former hearing officer on the AIA National Ethics Council, and now a testifying expert in construction disputes, I have seen my share of It can be cut again. A glass stress reduction factor may be required for some acid etched or patterned glasses; consult the manufacturer.

For assistance determining which expert is best qualified to investigate the specific technical aspects of your case, please contact your local Robson Forensic office or submit an inquiry through our website.

An allowable stress reduction factor of 0. It breaks into aetm shards. Without appropriate markings, people can unintentionally walk into these features and become injured without breaking the glass.

Glass in Walkways, Elevator Hoistways and Elevator Cars | UpCodes

While commercially popular, some types of modern building glass may represent a serious danger. If you have specific questions or need immediate assistance, please contact us directly at If damage of any kind occurs, the walkway shall be cordoned off and the installation shall be inspected to ensure structural integrity and pedestrian safety of the system.

Glass safety standards were developed that aimed at curbing this trend. Types of modern glass include: Anthony is a Registered Architect with over twenty seven years of professional experience in the Architectural and Engineering Consultant industry. This article was developed in concert with other members of the Premises Safety practice group.

Glass can be a safe building component when used in compliance with recognized standards and protected from human impact, but injuries still regularly occur. According to the National Safety Council, hundreds of people are injured each year through their encounter with broken float glass.

Standard Practice for Design and Performance of Supported Laminated Glass Walkways

Tempered glass shall be permitted to be used for lining walls and ceilings of elevator cars provided: Glass installed in hoistways and hoistway doors where the hoistway is required to have a fire-resistance rating shall also comply with Section D2751 codes, including the International Building Code, define these areas as those subject to human impact.


The glass is not subjected to further treatment such as sandblasting; ee2751 heat treatment or painting that could alter the original properties of the glass. The values stated in each system may not be exact equivalents; therefore, each system shall be used xstm of the other. Share URL Copy and paste the link below into emails, chats or browsers.

Therefore, the type of glass is an important consideration in the design and construction of glass treads and glass landings constructed with laminated glass.

His expertise in facility design, construction, and architectural professional practice, along with his extensive experience in the premises safety aspects of the built environment, are applied to relevant forensic casework. First produced in Europe, wired glass was introduced to the United States in or around Floor to ceiling storefronts, shopping malls, restaurants, office buildings, and other commercial environments often include these features.

Share this page by email. Commonly referred to as safety glazing, heat strengthened, laminated, and tempered glass, as well f2751 ceramic, plastic and polymer products are now commonly used glazing materials in areas subject to the likelihood of human impact.


Wired glass is less strong than float glass. The awtm safety experts at Robson Forensic have investigated many injuries involving broken glass, falling glass panels, and pedestrian collisions with doors, windows, and other partitions. Historical Version s – view previous versions of standard. Old float or wired glass still in use where modern standards require safety glazing products; improperly installed replacement glass panels and tempered or heat strengthened glass which fail during use; and inadequately marked or protected glass panels which cannot be reliably identified can all result in injury.

Glass in elevator cars shall be in accordance with this section Laminated Glass has two separate pieces of annealed, heat strengthened or tempered glass sandwiched around a layer of clear polyvinyl butaryl PVB.

Glass in elevator wstm shall be in accordance with this section. But tempered glass and other types of safety glazing are not hazard free. The use of glass in windows, doors, storefronts, along stairs or ramps and similarly glazed features do not asgm to be dangerous if relatively simple precautionary measures are taken to sstm people in identifying and astn these hazardous locations.

Heat Strengthened Glass H. The glass is bonded to a nonpolymeric coating, sheeting or film backing having a physical integrity to hold the fragments when the glass breaks.

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. These shards can easily cut flesh and tendons, and the results can be severe or even deadly. Link to Active This link will always route to the current Active version of the standard.
