Rack with several bays: one tag per bay if two people can lift at once. One usable bay, one tag.
Pull-up or dip station on a bigger frame: its own tag when it has its own approach position, otherwise fold it into the frame’s tag.
Attachments (bars, ropes, straps, ankle cuffs): no tag. They move between stations and get lost, not repaired. Members report them on the station they hang from.
Dumbbell, kettlebell, and plate racks: one tag per rack, never per weight. The rack is the asset.
Cardio with an attached screen: one tag. The screen is a part of the machine, not a station.
Shared spaces (locker room, turf, stretch corner): that is what Area Tags are for. Area Tags cover a space; they do not replace a tag on a machine.
A frame problem on a split machine (bent upright, loose bolt): report it on the nearest station and put “frame” in the note.
