What is a requirement for the design of vision panels in swing doors?

1. Design must include safety grips

2. Panels must be impact-resistant

3. Panels must maintain transparency

4. Materials must be weatherproof

The correct answer is: Panels must be impact-resistant

The requirement for the design of vision panels in swing doors to include impact-resistant panels is important for several reasons. Vision panels are glass or transparent materials installed in swing doors to allow visibility through the door. Since these panels are often located in high-traffic areas, they are at a greater risk of being struck by people, objects, or even vehicles. Impact-resistant panels help ensure safety by reducing the risk of shattering upon impact. This is crucial in preventing injuries that could occur from broken glass, as well as maintaining the integrity of the door structure and overall building safety. By incorporating impact resistance, the design not only enhances durability but also supports compliance with safety standards that aim to protect individuals in various environments, such as commercial or industrial settings. While safety grips, transparency, and weatherproof materials can be relevant in certain contexts, the priority in the design of vision panels specifically relates to safety and reducing potential hazards associated with impacts, making impact resistance the primary requirement.
