Layers of Protection Analysis and Safety Integrity Level (LOPA & SIL)
Safety, Health & Environment · 5 Days · Public · Al-Khobraa certified · From USD 3,900
Overview
This highly participative Layers of Protection Analysis training course combines both qualitative and quantitative elements of hazard evaluation and risk assessment to analyze and judge the adequacy of existing or proposed safeguards against process deviations and accident scenarios.
Learning Objectives
When and how to use LOPA
How to identify which scenarios from a HAZOP or other qualitative analysis could benefit from LOPA
How to systematically create risk scenarios for new processes or for existing processes under change
How to establish risk acceptance (risk tolerance) criteria for use within your company (this is also called the development of ALARP criteria) and how to depict this in a Risk Matrix or in a formula
SIL / PHA / HAZOP team leaders & scribes
Engineers involved in any aspect of the SIS Safety Lifecycle
Supervisors, managers, and engineers responsible for SIL studies
How to calculate “as-is” risk for a cause-consequence pair:
How to estimate the frequency of the initiating event
How to determine the consequence for the scenario (unmitigated)
Understand what is meant by “independence” and “uniqueness” with respect to the safeguard layers (IPLs)
How to calculate the value of each IPL
How to determine the risk of a LOPA scenario and how to determine how much further risk reduction (if any) is necessary
How to use LOPA to determine the Safety Integrity Level (SIL) necessary for an instrument IPL (to comply with the requirements of IEC 61508/61511 for safety instrumented systems)
How to document LOPA
How other companies worldwide use LOPA to:
Decide which PHA / HAZOP recommendations to reject and which to accept
Focus limited resources within mechanical integrity departments and operations on what is critical to managing risk to ALARP
Avoid wasting resources on the added cost and unproductive sophistication that often occurs when they instead quantify risk using QRA methods such as fault tree and event tree analysis

Accreditation
Al-Khobraa certified. On completion delegates receive an Al-Khobraa certificate of achievement.
What do Al-Khobraa safety, health and environment courses cover?
Al-Khobraa's HSE portfolio covers occupational health and safety management, process safety management (PSM), risk assessment, incident investigation, environmental management and safety leadership — including preparation for internationally recognised qualifications such as NEBOSH and IOSH Managing Safely. Courses are taught by practitioners with Saudi industrial experience in Arabic and English.
Who should attend a safety, health and environment course?
These courses suit HSE officers, safety supervisors and managers, operations and maintenance engineers, plant and site supervisors, contractor and project HSE staff, and any manager accountable for workplace safety performance. Most programmes assume practical site experience rather than a formal safety qualification.
How long are safety, health and environment courses, and where are they held?
Most Al-Khobraa safety, health and environment courses run over 5 days. The exact duration, dates and city for this course are listed in the dates section on this page. Public sessions run across Saudi Arabia — Riyadh, Jeddah, Al-Khobar, Jubail and Yanbu — as well as regional and international venues, with live virtual classrooms available on request.
What certificate will I receive?
Delegates who complete the course receive an Al-Khobraa certificate of completion, issued by a Saudi-registered training provider. Al-Khobraa also delivers internationally accredited programmes; where a course carries an external awarding body such as PMI, CIPS, ILM or IOSH, that body is named on the course's own page.
Can safety, health and environment training be delivered in-house for our team?
Yes. Any Al-Khobraa safety, health and environment course can be delivered in-house at your own premises anywhere in Saudi Arabia or the GCC, with the content, dates and language of delivery tailored to your team. Al-Khobraa is an approved HRDF (Hadaf) provider, so eligible Saudi employers can seek training support. Contact us for a quotation.
