What best describes safety glass?

• A. Two sheets of glass laminated to a sheet of plastic sandwiched between them; the plastic layer makes the glass stronger and more shatter resistant. Also known as Laminated Glass.
• B. A single sheet of tempered glass designed to shatter into blunt chunks.
• C. A type of glass used exclusively for windshields that never breaks.
• D. A standard plate glass used in windows.

Answer: (A)

Safety glass is designed to minimize injury when it breaks. The strongest match is laminated glass, which uses two panes of glass with a plastic interlayer between them. If the glass cracks, the interlayer keeps the pieces bonded together, so shards are less likely to fly apart. This interlayer binding is the key feature that defines safety glass in many applications, such as automotive windshields and certain building glazing.

Tempered glass is also a safety option, but it works differently: it’s designed to break into small, blunt pieces rather than stay bonded together. That’s why the description focusing on a plastic interlayer between two sheets best describes safety glass overall. Statements claiming the glass never breaks or describing plain plate glass don’t capture the safety aspect.
