Portable computing device assisted mustering

A tool for supporting mustering in a facility is provided. The tool includes a mobile computing device comprising a display unit, a memory and a processor. The memory has executable instructions of an application stored thereon, which, when executed, cause the processor to communicate with monitoring and control systems of the facility, to conduct a registration of the user of the mobile computing device and to display on the display unit an interface. The interface includes a first interface element by which the user indicates his/her safety level, a second interface element by which the user self-identifies as a mayor and a map. The map includes first information received from the monitoring and control systems, second information relating to predefined static muster points and third information relating to dynamic muster points of users self-identifying as mayors.
