Which statement correctly describes safety glazing requirements for doors?

The correct statement regarding safety glazing requirements for doors emphasizes that glazing positioned within 24 inches of either vertical edge of a door and less than 6 inches above the floor must be safety glazing. This requirement stems from the potential risk of human impact in these areas where visibility is critical for safety. The specification is designed to minimize injuries from accidental contact with the glass, which can lead to serious injuries.

Safety glazing is designed to reduce the likelihood of shattering upon impact, making it essential in locations where people are likely to come into contact with the glass, especially in high-traffic areas like doorways. The placement rule ensures that the most vulnerable areas are covered by safety glazing materials, reflecting standard practices in building safety codes.

The other options do not align with established safety standards: the first option incorrectly assumes that decorative glass does not need to meet safety standards, the second underestimates the necessary safety measures by only addressing glazing above the walking surface, and the fourth inaccurately states that only glass doors require safety glazing, while safety glazing requirements typically apply to various door styles and configurations.
