These products are less likely to break when subjected to impact and less likely to cause serious injury if broken. The glass in glass hoistway doors shall be not less than 60 percent of the total visible door panel surface area as seen from the landing side.

ICC Passes Two Glass Walkway Provisions

This standard includes performance, design, and safe behavior considerations. Glass is annealed glass that goes through a heating and cooling process designed to double its strength in comparison to ordinary annealed glass.

Glass can be a safe building component when used in compliance with recognized standards and protected from human impact, but injuries still regularly occur. Therefore, the type of glass is an important consideration in the design and construction of glass treads and glass landings constructed with laminated glass.

Glass in elevator hoistway enclosures and hoistway doors shall be laminated glass conforming to ANSI Z If you have specific questions or need immediate assistance, please contact us directly at Glass in elevator car enclosures, glass elevator car doors and glass used for lining walls and ceilings of elevator cars shall be laminated glass conforming to Class A in accordance with ANSI Z Your message has been received – we will be in touch shortly.

Standard Practice for Design and Performance of Supported Laminated Glass Walkways

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.


As a former hearing officer on the AIA National Ethics Council, and now a testifying expert in construction disputes, I aastm seen my share of Depending upon where and how they are used, even these products can be hazardous.

Laminated Glass has two separate pieces of annealed, heat strengthened or tempered glass sandwiched around a layer of clear polyvinyl butaryl PVB. Transparent glass walls where the glass cannot be atsm distinguished from the surroundings should be made conspicuous to prevent impact injuries. The use of glass in windows, doors, storefronts, along stairs or ramps and aastm glazed features do not have to be dangerous if relatively simple precautionary measures are taken to assist people in identifying and avoiding these hazardous locations.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For assistance determining which awtm 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.

It breaks into sharp shards. Types of modern glass include: According to the National Safety Council, hundreds of people are injured each year through their encounter with broken float glass.

Glass installed in hoistways and hoistway doors where the hoistway is required to have a fire-resistance rating shall also comply with Section Historical Version s – view previous versions of standard. When tempered glass breaks, it fractures perpendicular to the plane of the surfacerather than parallel to it, resulting in small cubes that are less likely to cause significant injury… Float glass was the most common type of glass used in buildings until recent times.

Glass safety standards were developed that aimed at curbing this trend. Float glass was the most common type of glass used in buildings until recent times.

Without appropriate markings, people atsm unintentionally walk into these features and become injured without breaking the glass. Floor to ceiling storefronts, shopping malls, restaurants, office buildings, and other commercial environments often include these features. His s2751 covers the various categories of glass, the use of glass in windows, doors, and partitions, and relevant safety standards.

Submit an inquiry or contact the author of this article to discuss your case and how we can assist. Wired glass is less strong than float glass.

ASTM E2751/E2751M – 17a

Glass is one of the most used materials in buildings and has been for the last years. The glass is bonded to a nonpolymeric coating, sheeting or film backing having a physical integrity to hold the fragments when the glass breaks.

Existing float glass can be covered with guards or a transparent film to prevent it from shattering and most glass can be easily removed and replaced with aztm appropriate safety glazing material. Written into fire and life safety codes for much of those 50 years, wired glass can still be found in buildings today.
