Why the clipboard roll-call is broken (and what replaces it)
Manual roll-call fails during real evacuations because it is slow, depends on wardens being present and correct, and produces no auditable record. Automated mustering replaces it with a live, timestamped head count that updates the moment each person reaches safety.
The problem with paper
A clipboard roll-call assumes everyone is where the register says they are, that the warden has the current list, and that people arrive at the assembly point in an orderly way. Real incidents break all three assumptions.
Worse, when the incident is over, there is no reliable record of when each person was accounted for — which is exactly what an investigation or regulator will ask for.
What good looks like
An automated system reads every tagged worker continuously. When the alarm sounds it already knows who is on site, and it updates a live head count as people reach muster points.
The output is a timestamped record: who is safe, who is still inside, and where they were last seen. That is the difference between hoping and knowing.
