System safety analysis: fault trees and FMEA
ASP written lesson, 10 min read. ASP Domain 2: Safety Programs and Concepts
AI-drafted from the cited rules and fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Contrast inductive and deductive system analysis methods
- Distinguish a fault from a failure when reading a tree
- Build a tree from a top event using immediate causes and gates
- Identify minimal cut sets and minimal path sets
- Calculate AND and OR gate probabilities for independent events
What this lesson covers
This lesson explains how FMEA and fault tree analysis differ, how a fault tree is built and reduced to cut sets, and how gate math turns component probabilities into a top event probability. It also covers FMECA criticality categories and the report lists reviewers expect.
