What this means on the day
An easy-to-use app for every user
Simple, guided interfaces help staff and fire marshals complete roll calls quickly under pressure. The mobile-first design works smoothly on smartphones and tablets, even in low visibility or high-stress situations, and clear prompts and alerts cut training overhead and increase adoption across your workforce.
Integrates with your existing access control and HR systems
Connect Musterd with access control systems, ID badges and other safety devices to automate presence data. Use phones, tablets and rugged devices at muster points for redundancy, and synchronise data across them in real time so every warden sees the same, up-to-date roll call.
Precise locations with what3words
What3words pinpoints muster points, entrances and high-risk areas to a three-metre square. Share exact locations with the emergency services and your own response teams to speed up assistance, and define precise indoor and outdoor gathering points for multi-site evacuations, even in complex or remote environments.
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.
