The paper presents a system monitoring operational safety of structures used in civil engineering. The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (OTDR) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its “nervous system”. The paper presents an example of an actual system operating based on FBG sensors and analysing the safety of Poland's longest steel footbridge. The footbridge is 35 years old. The applied monitoring system makes it possible to analyse the footbridge operational safety on a continuous basis. The system informs about hazards, overloads, vandalizing acts, etc., and points to the need to take appropriate measures including the footbridge shutdown. The information concerning the state of safety may be sent on-line to any corner of the globe.

Keywords: monitoring of stain, fibre Bragg grating, steel footbridge.
