04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For reliability, safety and asset engineers, safety case authors and regulators who need to quantify failure rates, build fault and event trees, set safety integrity targets and plan inspection and maintenance of ageing assets.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From a failure rate to a safety integrity level: how often a protection fails on demand
A component's failure rate and the share of its failures that stay hidden set how often a safety function is silently broken; the proof-test interval sets how long it stays broken; together they give the probability of failure on demand, the quantity that places the function in a safety integrity band.

12Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in reliability, safety and resilience engineering?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
