Advanced Safety Integrity Level (SIL) Selection (EC52) builds upon the foundation set in ISA's Safety Instrumented Systems: A Lifecycle Approach (EC50) and explores examples of SIL selections through different techniques and determinations of risk reduction requirements. Students will be better able to save their companies time and money by knowing how to optimize system performance requirements.
Required Prerequisite
Successful completion of ISA Safety Instrumented Systems: A Lifecycle Approach (EC50) and a passing grade for the ISA Certificate Safety Instrumented Systems Certificate exam are required prerequisites for EC52.
Who should attend EC52?
- Control systems engineers and managers
- System integrators
- Plant managers
- Plant safety and risk management personnel
