We are working on a project of a shopping mall. The building has a few delivery entrances (on the ground level and underground level) next to the delivery docks. These entrances will be used only by the delivery staff to deliver products to the shops. The question is if these entrances also need to be equipped with entryway walk-off systems? Standard building occupants won't use them. Moreover, delivery carts will be taken via these entrances and so it's not really practicall to install walk-off systems there.
In the underground parking lot there are also elevators for delivery only - do these elevator halls need walk-off mats?
