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 Electro technical 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 one sight visit day to a company related to their jobs specification (Petrochemical Company).
By the end of the training, participants will be able to:
- Apply and gain an in-depth knowledge on OSHA Process Safety Management (PSM)
- Learn how to perform a LOPA study to evaluate the effectiveness of process safeguards
- Be able to determine required SILs for SIFs using LOPA, risk graphs and risk matrices
- Improve safety skills through techniques in process safety management
- Promote business continuity improvement through understanding of safer systems design.
