Claim 6:
7. A surveillance system for work in a facility to minimize fire risk, comprising:
a server;
at least one radio beacon at a location of work, the at least one radio beacon repetitively transmitting a radio signal including an identifier of the at least one beacon and a coordinate location of the at least one beacon;
a first mobile device and a second mobile device, the first mobile device being associated with a first worker who is qualified to perform work using fire, the second mobile device being associated with a second worker, both the first and second mobile devices being configured to receive the radio signal transmitted by the radio beacon, and wherein the first and second mobile devices are in communication with the server via a communication network;
the first mobile device is configured to transmit to the server a request for an e-permit for starting work, the request including
an identity indication of the first worker,
an identity indication of the second worker,
an identification of work, including
start and end times of the work,
identification of the location of work, based on the location of the radio beacon as indicated in the signal transmitted by the radio beacon and received by the first mobile device,

the server is configured to process the request and grant the e-permit when the request is complete and the server verifies that the first worker meets requirements for work with fire based on the identity indication of the first worker in the request,
and, when the e-permit is granted, the server is configured to send the e-permit for starting work to the first mobile device,
the first mobile device is configured, in response to the e-permit, monitor its position status periodically based on a signal strength of the signal from the radio beacon as received by the first mobile device, and send the result to the server, wherein, on the basis of the signal strength, the first mobile device indicates it is one of present at the location of work, moved away from the location of work, or left the area of work,
the server is configured to generate a first alarm by applying measures selected from a group including: push notifications sent to mobile devices, SMS gate messages, voice calls to mobile devices, e-mail messages and triggering signaling devices, when a first criterion based on the position status of the first mobile device with respect to the location of work is met during the time between the start and the end of work indicating that first mobile device is away from the location of work, and
the server is configured to surveille the location of work in response to the server receiving an indication that the work is completed, including periodic determination of the position status by the first and second mobile devices based on the strength of the radio signal transmitted by the location beacon as received by the first and second mobile device and periodically sending the position statuses to the server (S) for a specified surveillance time of at least 60 minutes; and
the server is configures to generate a second alarm by applying measures selected from a group including: push notifications sent to mobile devices, SMS gate messages, voice calls to mobile devices, e-mail messages and triggering signaling devices when, during the specified surveillance time after the end of work, a second criterion based on the position status of the first and second mobile devices with respect to the location of work indicting that both the first and second mobile device have left the location of work.
