Cracks
Where glass is used as a part or whole of a building facade, roof, canopy or other overhead glazing (such as sunshade, fins or rain shield) locating at a height of >2.4m, it may be float glass, heat strengthened glass, tempered glass, laminated glass or any other types of glass. Regardless of the type used, the glass must comply with Singapore Standard SS341:2001 – Specification for Safety Glazing Materials for Use in Buildings.
Specifically, if monolithic tempered glass, heat-soaked tempered glass or any other type of glass that is prone to spontaneous breakage is used here, the design of the building shall provide for suitable protection such as installation of screens or shields, or presence of canopies or ledges, to protect people from injuries in the event of breakage of such glass element.
