SIL

Assignment of Safety Integrity Levels (SIL) was introduced as a measure of the quality or dependability of a system which has a safety function. It is a statistical representation of a Safety Instrumented System (SIS) when process demand occurs.

• ERS provides a range of SIL services using varying techniques including:
• Layer of Protection Analysis (LOPA)
• Consequence Only
• Risk matrix
• Fault Tree Analysis
• Where specialised software is required, ERS has existing partnerships with organisations that specialise in this field.
