We have industry-leading courses developed to cover almost every aspect of the functional safety life-cycle. We provide on-site training, online instructor-led training and online self-paced courses.
If you have never been involved with a safety system project, it is not necessarily immediately obvious what needs to be done, in which order, and by who. The standards provide a framework, but it takes experience to know what is important and what isn't.
We have that experience from many projects. The poorly handled projects tend to go wrong because the need for writing and following a functional safety plan simply haven't been recognised early enough.
We can provide a template plan and work with you to adapt that to meet your detailed project requirements and help manage your project more effectively.
Functional Safety Assessment (FSA) is required for any new or modified Safety Instrumented System (SIS), according to EN 61511 (edition 2, 2016).
FS Assessment and audit are also a requirement during the operation and maintenance phase of an SIS. The intention is to periodically carry out assessment and audit activities to sustain safety integrity.
Once we understand your project scope, we produce a detailed plan which clarifies what we will assess and/or audit, and how. A typical approach for an FSA project will involve a period of document review, followed by meetings to interview project and personnel. Using a clearly defined FSA protocol, our lead assessor will talk your team through the process, ensuring that the plan is followed to a conclusion.
We deliver a professional FSA report with a clear management summary of the findings and if necessary, recommendations for improvement.
We can facilitate your team in determining process hazards and operability issues using the HAZard and OPerability (HAZOP) methodology.
Guided by IEC 61882 or your own HAZOP procedure, we always record a HAZOP such that later phases of activity such as LoPA or other forms of SIL study will have the necessary detail.
It is your process and your hazard, so it must involve your team. You provide team members from operations, maintenance, process, safety, EC&I and any other required specialists. The team should be assembled from senior staff with sufficient experience of the operations of the facility or similar facilities.
eFunctionalSafety prepares the HAZOP nodes for study and get your preferred recording tool ready so that your valuable resources do not waste any unnecessary time. We chair the HAZOP meeting and record all the team discussions and conclusions. We can provide our own software or use your preferred tools.
At the end of the study, we deliver a numbered list of actions for you to get started on. Within one to two working weeks of the meeting conclusion, we deliver a professional report outlining the full study findings.
We can facilitate a Control system / Computer HAZOP (CHAZOP) on control and safety instrumented systems that are undergoing upgrade or significant modification.
This specialist support requires a sound technique which we provide in the form of a CHAZOP procedure with well-developed checklist.
LoPA is becoming the "go-to" method for many companies in the determination of protection layer credit. With the correct tolerable risk guidelines it can be used to determine the Safety Integrity Level (SIL) for your instrumented protection functions.
We can provide an experienced LoPA facilitator who will guide your team in correctly applying the technique without the need for costly re-work.
Safety requirements are the cornerstone of any safety instrumented system (SIS) or safety related electrical control system (SRECS) project. Requirements have to be carefully prepared and kept up to date.
We can provide starting templates that have been proven on previous projects and then support the development and update of the requirements for your project.
Devices being used in safety functions need very careful selection. We have the experience to be able to look at your preferred sensors, logic solvers and final element equipment and give an unbiased view about the SIL capability that can be achieved by the design.
This service is usually a precursor to SIL verification, but can be provided as a stand-alone assessment if required.
Design verification of Safety Integrity Level (SIL) is required for all projects that wish to demonstrate that safety functions meet best practice engineering. We can help to provide your evidence of meeting probability of failure (PFD or PFH) and hardware fault tolerance (HFT) for any SIL requirement. We have significant project experience working with IEC 61508, IEC 61511 for process safety and IEC 62061 for machinery.
We can also assist with verification services for only part of a function such as a final element valve & actuator.
Either as part of a functional safety assessment, or as an individual service, we can provide design assurance that application programs (software) have met best practice standards.
We do not write the code, but we do have the experience of reviewing detailed PLC software design specifications that use ladder logic, function block diagram and sequential function chart.
We can assist at the testing and validation stage of a safety system project by helping to write the necessary test plans. Typically our involvement is best engaged at or after the Factory Acceptance Testing (FAT) of a new or modified system.
If we're not involved in the project development or writing the test plans then we can provide a fully independent Functional Safety Assessment (FSA).
eFunctionalSafety provides functional safety training and consulting services based upon many years of project experience in diverse industry sectors.
If your goal is compliance with IEC 61508, IEC 61511, IEC 62061 or a related industry standard, then we can help you with functional safety assessment and audit services (FSA).

We supported a major new refinery project destined for Kuwait by providing the SIL study facilitator for three different units - Hydrogen Production Unit, Amine Regeneration Unit and Sulphur Recovery Unit. The project support was provided in phases, leading multi-discipline engineering teams of 15+ people in the SIL study workshops. Our deliverable was a SIL determination report, ready to be used by the project team in the creation of the safety requirements specification for the safety instrumented functions on the project.
