Mustering solutions: ways to account for occupants

Emergency mustering is an essential part of emergency response, enabling organizations to verify which personnel are safe and who is still unaccounted for and may need rescuing. 


Here, we introduce three different mustering solutions and their advantages:


Handheld devices

Adopting a handheld device allows for mustering ‘on the go’ which can be carried out at any location, not necessarily at the site’s assembly point. The handheld device looks like a mobile phone and functions as a handheld reader. Evacuees are accounted for by simply swiping their card on the device, registering them against the list of personnel on the site’s access control system. A list of unaccounted for personnel is generated automatically and includes each person’s last recorded location, providing vital information for first responders on a rescue mission.


Handheld devices can be powered over Wi-Fi, mobile network or in standalone mode, and generally come with integrated card, fingerprint or face verification sensors. The key advantage of using a handheld device is the flexibility they provide for the location of the mustering point.

Real time location system (RTLS)

A real time location system (RTLS) provides a comparatively automated method of mustering with minimal human input required. Since the RTLS provides the location of each person on the system in real time, evacuees do not need to present themselves at the mustering point and swipe their credentials. Additionally, the evacuee’s well-being can also be provided by the system, as well as information about environment conditions on site and movement in unauthorized areas. This vital information can assist first responders reach personnel in the fastest possible time and with the necessary medical supplies, if required.


RTLS tags have an integrated panic button which can emit “SOS” signals to control rooms enabling those in need to call for attention.  


For larger premises, a RTLS is an extremely effective mustering solution, particularly in the event that personnel are trapped in the premises and need to be rescued. 

AI-powered LIDAR-based mustering solution


In an extreme emergency, like an explosion or an earthquake, evacuees may not be able to carry their mobile phone or credentials while fleeing the premises, or may not be able to reach the assembly point which might have been compromised. In such circumstances, mustering is very challenging. This is when an AI-powered 3D LIDAR-based mustering solution is useful and effective.


This solution requires AI-powered LIDAR (light detection and ranging) sensors to be installed at all the entry and exit points of a building to monitor the movement of people in and out of the designated points. The generated metadata is processed by a user-friendly flow management software built on machine learning and 3D perception algorithms, yielding the real time occupancy count on the premises, albeit anonymous.


This solution provides the count of people mustered and the count of people occupying the building with an accuracy level of over 98%. Whilst limited in providing information regarding which personnel are unaccounted for, this solution is highly effective in determining how many people are still in the premises and need rescuing.
