5.3. Vision Panels

• Transparent doors must have vision panels to prevent collision.

Vision panels are transparent sections of doors. Their main purpose is to allow visibility through the door, which helps to prevent accidents where someone might walk into the door because they cannot see it. This safety feature is essential in building design, especially for locations with a lot of foot traffic.

Think of a busy café with glass doors. Without the transparent panels, a person walking towards the door might accidentally bump into it. Vision panels work like a window, letting people see what's on the other side and avoid collisions.

• The bottom edge of the panel should not be more than 900 mm from the floor.

The height limit for the bottom edge of the vision panel is set at 900 mm from the ground. This height is designed to ensure that both children and shorter individuals, as well as people using wheelchairs, can easily see through the panel. The regulation minimizes blind spots and enhances visibility for users.

Imagine a small child in a shopping mall. If the vision panel is too high, they might not be able to see out, potentially leaving them confused or causing them to walk into the door. By ensuring that the panel is within reach, we provide a safer environment for everyone.

• Frosted or obscured glass should have high-contrast warning strips.

Frosted or obscured glass doors can be problematic as they do not provide a clear view of what is on the other side. To make them safer, high-contrast warning strips are added. These strips serve as visual cues, alerting people to the presence of a glass door and encouraging them to be cautious, thereby preventing collisions.

Think of a shower door made of frosted glass; while it ensures privacy, it can be hard to see through. By adding bright warning stripes to the door, someone walking toward it can notice the markings and become aware of the door's location, just like how caution tape signals a barrier.
