Mazuran Standard Practice for Design and Performance of Supported Laminated Glass Walkways His discussion covers the various categories of glass, the use of glass in windows, doors, and partitions, and relevant safety standards. 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 an appropriate safety glazing material. Float glass was the most common type of glass used in buildings until recent times. An allowable stress reduction factor of 0. Glass walkways, while less common, are also required to comply with a nationally recognized standard. Tempered glass shall be permitted to be used for lining walls and ceilings of elevator cars provided: Heat strengthened and tempered glass break into rounded cubes which may still contain sharp edges, but do not form dagger-like shards.
