Security Bollards [7.4] and Security Devices

Bollards and rails used to keep shopping carts on the premises must allow an accessible clear passage (32 inches wide minimum) along at least one route for entry and exit. Alternative entries and accessible gates [4.13.3] can be used as long as they are not less convenient than other routes. For example, gates allowing wheelchair access cannot be locked or alarmed during times when the general public has unhindered access to the facility.

Inventory Control Devices

It is important that inventory control or security devices not obstruct required maneuvering clearances at doors. A minimum 12 inch clearance is required on the push side of swinging doors when the door has both a closer and a latch. This clearance is often useful at exterior doors without latches in countering the force of closers and wind resistance. When doors are automated, maneuvering space is not required.
