The human body impacting a panel of glass to the point of breakage is at serious risk for greivous injury or death. Obviously barefoot and swimsuit clad people would be at greater risk but where there is a pool there is more likely to be a slip and fall resulting in that broken glass.
Modern building codes call for safety glass, either tempered or laminated, to be installed in certain areas. Even these legal codes may not go far enough in requiring safety glass in all critical areas. Buildings more than thirty years old may not have safety glass installed and could be a danger should a human body impact the glass. A retrofit installation of clear safety film can meet ANSI Z97.1 standards, protect people from broken glass and can also help keep a broken panel from falling down. If broken, the glass usually stays up and inside the frame. Great reasons to limit your exposure to a costly lawsuit or worse!
Bullet impacts in glass at a light rail station. Broken and ready for replacement but the panel is still up and inside it's frame, sandwiched between two layers of tough, 7 mil thick securtiy and graffiti protective film. No sharp glass fragments for the public to come into contact with.
