This course focuses on the principles involved in the design of safety instrumented systems (SIS) that conform to the requirements of ANSI/ISA-84.00.01-2004 (IEC 61511 Mod). In this intensive 2-day course, we will teach you how to evaluate the need for a safety instrumented function (SIF), evaluate potential system architectures, and analyze the system to determine its predicted performance, from both a risk reduction and reliability standpoint.

Combine this course with Layer of Protection Analysis and save!
