Risk, Reliability & Functional Safety Knowledge Base

A structured overview of the most important risk, reliability, and safety analysis techniques — from HAZOP and FMEA to fault trees and Markov analysis.
Whether you are a decision-maker setting strategy or an engineer seeking the right tool for a project, this guide provides a roadmap for navigating the world of risk management.

Job Safety Analysis identifies hazards in work tasks before they cause harm. Learn the JSA process, how it fits into a safety management system, and how to use it effectively.

Event Tree Analysis models the consequences of an initiating event through a series of binary branches. Learn how ETA works, when to use it, and how it supports risk assessment.

The title Certified Specialist has a specific meaning in the Risknowlogy certification framework. Learn what it represents, how it is earned, and why it matters for functional safety professionals.

The Markov technique models system states and transitions to quantify reliability and safety. Learn how it applies to IEC 61508 and when to use it over simpler reliability methods.

HAZOP is a structured technique for identifying hazards in process systems. Learn how HAZOP studies work, what IEC 61882 requires, and how to apply it effectively in your organisation.

HAZID is an early-stage hazard identification technique used in process safety and risk management. Learn how it differs from HAZOP, when to use it, and how to run a HAZID study.

A safety-first culture is the foundation of effective functional safety management. Learn how to build it, sustain it, and align it with IEC 61508 and IEC 61511 requirements.

Companies that demonstrate functional safety compliance can reduce their insurance exposure. Learn how to quantify safety measures and use them to justify lower insurance premiums.

Risk mitigation in functional safety requires structured, evidence-based strategies. Learn five proven approaches to reducing risk in process plants, SIS projects, and safety lifecycles.
