Safety prevention measures for automatic doors
For investors and contractors
To enhance safety, it is recommended to use framed glass door panels (aluminum or stainless steel frames) to prevent accidents caused by glass breakage in the event of impact. Frameless glass panels (tempered glass without frames) should not be used.
The use of frameless glass panels (tempered glass without frames) is not recommended in high-traffic areas such as hospitals, shopping malls, office buildings, or public spaces. Selecting the correct automatic door configuration from the outset helps improve safety levels while minimizing risks and future repair costs.
For users
- Do not rush through the door. Avoid approaching the door diagonally.
- Do not stand in the doorway and obstruct the door’s opening or closing movement.
- Do not lean on the door leaf, glass panels, or step on the door.
- Do not stand chatting near the door or allow children to play around it.
- Be cautious of finger entrapment between two door leaves.
- Hold children’s hands when passing through the door. Pay special attention when people with disabilities or visual impairments are passing through.
Quick troubleshooting steps
