RTLS supports emergency mustering by showing, during an evacuation, who has reached an assembly point and who is still inside, with each person's last known location. People wear tags that report position to readers or anchors around the building. When an alarm is raised, readers at muster points check people in automatically, and the system produces a live list of anyone missing. That replaces paper roll calls, which are slow and depend on accurate sign-in sheets, and tells responders where to search first. It works only for people carrying a charged, working tag.
Mustering belongs in the emergency action plan; see Forklift emergency action plans. OSHA 1910.38(c) requires the plan to include procedures to account for all employees after evacuation, and RTLS is one way to carry out that duty, not the duty itself.
Check that muster-point readers and the server have backup power, that the system keeps working if the network fails, and that visitors and contractors receive tags at the gate. Where tags already serve forklift proximity detection, the same infrastructure can often support mustering; RTLS for forklift safety covers the technology options. Keep a manual headcount as a fallback and drill both.
