Final answer:
Safety glass is required at glazing near doors, tubs, or showers to reduce the risk of injury in case of breakage.
Step-by-step explanation:
Safety glass is required at glazing near doors, tubs, or showers. This is because these areas have a higher risk of impact or damage, and safety glass is designed to reduce the risk of injury in case of breakage. Safety glass is made with laminated or tempered glass, which is stronger and less likely to shatter into sharp pieces.
