Ensuring That Safety Glass Is Safe

Publication: Journal of Legal Affairs and Dispute Resolution in Engineering and Construction
Volume 15, Issue 1

Abstract

In Australia, the building code prescribes where glass in buildings must adopt certified safety glass. However, this standard still permits the certification and installation of toughened glass with a residual surface stress that is insufficient to ensure fragmentation in a safe manner. Until the standard is amended to assure safe fragmentation, other precautions need to be taken to ensure that glass installed in buildings is not potentially lethal. This paper discusses safety glass testing, explaining why the current testing procedure does not assure safe fragmentation, and, in the absence of adequate statutory-backed guidance, how building surveyors should navigate the compliance pathway for toughened safety glass.
