Purpose: Adhesive circles are designed for marking glass doors, partitions, display windows, and other large glass surfaces. They help make transparent obstacles more visible and improve accessibility within the environment. The color of the circles should be chosen to ensure the markings stand out clearly against various backgrounds and lighting conditions; their size, height, and placement should be determined based on the specific project requirements and regulations applicable to the site.

Hazard: Due to transparency, reflections, or similar background conditions, unmarked glass can be difficult to notice. This creates a risk of collision and injury, particularly for individuals with visual impairments.

Behavior: Upon noticing the markings, one should take note of the glass surface and choose a safe path. The stickers should be applied to a clean, degreased, and dry glass surface, following the designated layout for the markings.
