Тhe requirements for a new layer in the industrial safety systems
Plan The main task Safety-protective layer
The main task
Safety-protective layer
The risk reduction methods that do not involve shut-downs are robust design of the process installation due to conservative design and high quality of construction and operation hardware and software-based redundancy of control system components; properly designed visualization of the process; auxiliary alarm-advisory systems; operators training, particularly with the use of the process simulators, which allow simulation of process emergency scenarios; the on-line diagnostics of the process and field devices; Fault Tolerant Control Systems (FTCS).
