Traditional fire and gas detection system design techniques are often considered unsatisfactory due to their nature of being rule-of-thumb and experience oriented without any real ability to quantify risk. This has resulted in systems that are either over-designed or under-designed. The advent of the IEC 61511 standard caused a shift toward quantitative analysis for instrumented safeguard design, but failed to solve the fire and gas problem because it was not comprehensive enough to consider the real problem, detector coverage. After release of ISA TR 84.00.07, a comprehensive framework for performance-based fire and gas design established. This course describes the techniques recommended in the technical report, along with hands-on application of the techniques with associated software tools. The course includes a comprehensive case study that involves employing the Kenexis Effigy™ software to develop a complete performance-based design for a sample oil and gas production facility.

The online course provides an overview discussion of Layer of Protection Analysis (LOPA) and is designed as a refresher for participants. Layer of Protection Analysis. LOPA is an abbreviated methodology for quantifying the risk associated with process plant hazard scenarios. The methodology uses broad categories, including order of magnitude, consequence, initiating event likelihood, and the beneficial effect of protection layers, such as operator intervention, safety instrumented systems, physical relief devices, and mitigation and emergency response.
Understand the safety instrumented system lifecycle
Understand how hazards are assessed to ensure that tolerable risk is achieved
Understand the concept of an independent protection layer
Understand how required risk reduction is determined and allocated to independent protection layers
Process safety management (PSM) is the process by which unexpected releases of toxic, reactive, or flammable materials in processes involving highly hazardous chemicals are prevented. In the United States, PSM is defined by the Occupational Health and Safety Administration (OSHA) regulation 29 CFR 1910.
This online training module provides an overview level presentation of PSM and the standards that define how PSM programs are developed and what they contain. The module begins a discussion of the origin of the standard, where it applies, and the authority under which it was created. The module then goes on to describe each of the fourteen elements of PSM, starting with Process Safety Information, moving through Process Hazards Analysis, and going on to Pre-Startup Safety Reviews, and much more. Upon completion of the module students will understand where PSM applies, and what is required to implement a compliant PSM program.
Understand what the PSM rule is, why it was written, and what authority allowed for the creation and enforcement of the rule upon US industry
Learn to determine what facilities are sections of facilities are covered by the PSM rule based on threshold quantities of highly hazardous chemicals
Understand how facilities are broken down into monitored areas and how those areas are described in the overview section of each study

Complete a pre-instructional survey, download and read supporting documentation, view lectures, and perform a post-instructional exam
The Security PHA Review training module provides an in-depth explanation of the rigorous process for starting with a process risk analysis report, such as a hazards and operability study (HAZOP), and reviewing the document to determine the vulnerabilities that the equipment under study might have to cyber-attack, and then propose and document recommendations to either make the process inherently safe against cyber-attack or recommend an appropriate Security Level (SL) in accordance with the ISA/IEC 62443 standard.
Provide background on cyber-attacks against industrial control systems
Present an overview of the contents of the 62443

The Safety Requirements Specifications (SRS) training module provides a detailed presentation on the concepts and application of instrumentation and control design techniques that are required to prepare documentation that will become the basis of subsequent detailed design activities and ongoing management of change of a Safety Instrumented System. The training course presents a discussion of the requirements for conceptual and detailed design that are required to be documented. The training course will expand on these topics, presenting the requirements, explaining what the requirements mean, providing a number of different options that are available for fulfilling the requirements, and discussing the strengths and limitations of the options.
