Course Description

Oil, gas and chemical field companies handle the most dangerous chemicals and processes across all industries. Catastrophic incidents and casualties are products of the failure to manage process safety
The international and US standards for Safety Instrumented Systems (SISs), International Electrotechnical Commission IEC 61511 and ISA 84, require that Safety Integrity Levels (SILs) be determined for Safety Instrumented Functions (SIFs) to meet tolerable risk criteria. The standards identify several methods that can be used for this purpose including Layers of Protection Analysis (LOPA), risk graphs and risk matrices. This course explains how these methods can be used. A detailed procedure is provided for using LOPA for SIL determination.Course participants will have sight visit day to a company related to their job specification (Petrochemical company).

Course Objectives

  • Gaining an in-depth knowledge of OSHA Process Safety Management (PSM)
  • Learning how to perform a LOPA study to evaluate the effectiveness of process safeguards
  • Being able to determine required SILs for SIFs using LOPA, risk graphs and risk matrices
  • Improving safety skills through techniques in process safety management
  • Promoting business continuity improvement through understanding of safer systems design
