Interactive Site Maps
See your site as zones on a map, with unsafe areas flagged and cleared areas marked as the sweep goes on.
Musterd shows your sites, buildings and muster points on an interactive map. Divide each site into zones, and marshals sweep them in order and confirm each one clear, by name and with the time it happened.
Unsafe zones stand out at a glance, along with each person’s last known location, so incident managers can see where the gaps are and send help where it is needed.

What Interactive Site Maps does for you
Zones swept and cleared, in order
Divide production halls, warehouses, floors and yards into zones, and marshals sweep each one and mark it clear. The map shows which zones are cleared and which are still to be checked, so nothing is skipped.
Unsafe areas visible at a glance
Unsafe zones are flagged on the map alongside the last known locations of anyone not yet accounted for. Command teams see where the gaps remain and direct search and rescue to them first.
Plan routes as your estate changes
Use the map to plan and test evacuation routes and muster points as your buildings change, and share exact locations with what3words, so the emergency services and your own teams go straight to the right place.
