Check-In Arrangements
The cheapest lone worker control and the one most often designed so that a missed check-in means nothing.
Procedure
The response chain
The links that actually fail: the one with nobody in it at three in the morning, the list with a wrong number, and the alert nobody believes any more.
9 notes
The Escalation Tree
Who is called, in what order, and what they are authorised to do. Written down, or it is improvised at the worst moment.
Procedure
Who Watches the Alerts
Three arrangements for the person at the other end, what each costs, and the question that decides between them.
Analysis
Raising an Alarm Without Showing It
The case where pressing an obvious button makes things worse. Discreet activation, and the false reassurance around it.
Analysis
Knowing Where to Send Help
An alarm without a location is a problem without an address. What the systems actually provide, and the gap that matters indoors.
Analysis
False Alarms
The failure that kills these systems quietly: enough false alerts that the responder stops taking them seriously.
Analysis
After Something Happens
The hour afterwards, the days afterwards, and the review that finds a cause rather than confirming the system worked.
Procedure
How Long Everything Actually Takes
The timings that constitute the system, how to measure each, and the figure that matters more than any device specification.
Analysis
Investigating Properly
The sequence that finds a cause rather than a culprit, and the four questions an investigation must ask beyond what the worker did.
