Real-Time Data
Modern evacuation management depends on live information. Musterd’s real-time data engine shows, at every moment, who is on site, who is off site and who is missing.
- Who is on site
- Who is off site
- Who is missing
What this means on the day
Live dashboards
Live dashboards show who has checked in at each muster point and who is still missing. The roll call updates automatically as people scan badges, use the app or are marked safe by wardens, and incident commanders can filter by building, floor, team or role to prioritise critical personnel.
Faster decision-making during emergencies
A clear on site, off site or unknown status reduces guesswork and delays at muster points. Fire marshals receive up-to-the-second information on their teams, so they focus searches where people are most likely to be, and command teams adapt routes and instructions to the live headcount rather than an outdated paper list.
A complete audit trail for compliance and post-incident review
Every check-in, status change and roll call action is time-stamped and stored. Digital records support compliance with internal safety policies and external regulations, and post-incident reports highlight bottlenecks and response times so you keep improving.
Works with your existing systems
Musterd can be integrated with a range of systems that hold employee data. That removes the need to enter staff into the roll call system by hand, and keeps it up to date as people join and leave.
