Is plate glass considered safety glass?

Plate glass is not classified as safety glass. Safety glass is specifically designed to reduce the risk of injury in the event of breakage. It typically includes glass types like tempered glass and laminated glass, which undergoes special processing to enhance its strength and integrity or to hold shattered pieces together.

Plate glass, while it can be clear and aesthetically pleasing, does not have these safety features inherently. When plate glass breaks, it shatters into large, sharp shards that can cause serious injuries. Thus, it does not meet the criteria for safety glass.

The other options suggest conditions or scenarios under which plate glass might be considered safe, which does not align with the standard definitions in safety regulations. Hence, plate glass remains classified as non-safety glass regardless of the situation.
