We Strive to Drive
Safety Culture
A Safety Integrity Level (SIL) study is a systematic analysis and assessment of the functional safety of safety instrumented systems (SIS) used in industrial processes. These studies are commonly performed in industries where the consequences of failures could result in serious harm to people, the environment, or property. The goal of a SIL study is to determine the required SIL for safety instrumented systems and ensure that they meet the desired level of risk reduction.
Safety Integrity Level is a measure of the risk to people and property that a system will experience during operation. The Safety Integrity Level is a qualitative measure of safety and it is expressed in terms of the consequences of failure. The higher the Safety Integrity Level, the lower the likelihood of failure and, therefore, the better the safety.
Safety Integrity Level study is a method to record all the SIF for a project development and document the expected reliability level. Safety Integrity Level study provides a basis for future maintenance and operating strategies. Safety Integrity Level assignment is based on the amount of risk reduction that is necessary to mitigate the risk associated with the process to a tolerable level. All of the Safety Instrumented Systems (SIS) design, operation and maintenance choices must then be verified against the SIL assigned.
The SIL study process is highly structured and relies on quantitative and qualitative analysis to ensure that safety instrumented systems effectively reduce risks to an acceptable level. These studies are commonly used in industries such as chemical, oil and gas, pharmaceuticals, and nuclear power, where process safety is critical.

The primary objective of the SIL study is to determine the adequacy of Independent Protection Layers that are in place to mitigate against hazardous events relating to major process hazards.
The study will determine the risk reduction required for the SIFs such that sufficient Protection Layers or safeguards to allow them to meet the required risk reduction for a particular hazard. Quantification of the risk reduction requirements is given in terms of SIL requirement.
The key rule set for the Safety Integrity Level study is provided below
There are several methods used to assign a SIL. These are the normally used in combination, and may include:
LOPA method for SIL classification has been utilized for SIL Study.
