    The Instrumented Safety Level or SIL is a risk identification method that analyses the function of each automated facility protection mechanism, such as automatic valves, sensors, relays and other instruments that detect abnormal operating conditions of the process and equipment such as flow, temperature and pressure.

    Furthermore, the SIL classifies the level of safety requirements for each instrument or safety function of the system. With this objective, it evaluates the potential damages that its failure can cause to people, the environment and production.

    The SIL method requires a previous HAZOP study, which identifies the required security instruments, pointing out which of them need a SIL analysis.

    TEMA has extensive experience in the usage of these basic tools in safety and prevention of potential risks in industrial activities.
