The impact of the beam particles of the LHC can cause severe damage on the superconducting magnets, resulting in significant downtime for repairing. The Beam Loss Monitors System (BLMS) detects the secondary particles shower of the lost beam particles and initiates the extraction of the beam before any serious damage to the equipment can occur. The main goal for the BLMS in term of reliability is the design of a system minimizing both the probability to not detect a dangerous loss and the number of false alarms generated. The presentation introduces the reliability theory and shows the techniques used to provide an estimation of the probability to damage a magnet, of the number of false alarms and of the number of generated warnings. The implemented model allows future modifications of the system, following the measuring of the hazard rates during the LHC life.
