Where would you NOT need safety glazing?

The correct choice reflects a scenario where safety glazing is generally not required. Dual glazing, which involves two panes of glass in a single unit, is typically used for energy efficiency and noise reduction. Since the outer pane of dual glazing can be made of tempered or laminated glass, which already meets safety requirements by being less likely to shatter into sharp shards upon breaking, there is no specific mandate for it to be safety glazing.

In contrast, the other options, such as glass doors, shower enclosures, and windows in living areas, often require safety glazing as a precaution against injuries resulting from breakage. These locations are more prone to impact or are at risk of being touched frequently, necessitating materials that minimize injury risk in case of breakage. Therefore, identifying that dual glazing may not require specific safety glazing helps differentiate it from areas where safety is a significant concern.
