Structured hazard identification - IEC 61882 HAZOP worksheets with deviation-to-NeqSim-calculator mapping, FMEA with RPN scoring, event trees, fault trees with beta-factor common cause and minimal cut sets, escalation (domino) screening. USE WHEN: a task needs systematic hazard identification, quantified HAZOP/HAZID deviations, top-event decomposition or domino analysis. Anchors on neqsim.process.safety.hazid, .risk.eta, .risk.fta and .escalation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeqSim HAZID / FMEA / ETA / FTA Skill The four canonical hazard-identification and scenario-development techniques in one place — used together they produce auditable HAZOP / SIL / QRA documentation per IEC 61882, IEC 61508/61511, ISO 17776 and the CCPS guideline series. ## When to Use - HAZOP node walkdown — apply guidewords to design intent at every node - FMEA / FMECA — equipment-level failure-mode tabulation with RPN scoring - Event-tree analysis (ETA) — outcome-frequency development from initiating event - Fault-tree analysis (FTA) — top-event decomposition, minimal cut sets, β-factor CCF - Escalation / domino analysis — graph of adjacency between fire/explosion sources Pairs with `neqsim-process-safety` (LOPA / SIL / risk matrix) and `neqsim-consequence-analysis` (probit / IRPA roll-up). ## Standards - **IEC 61882** — HAZOP studies — application guide - **IEC 60812** — FMEA / FMECA procedure - **IEC 61025** — fault tree analysis - **IEC 61508 / 61511** — β-factor common-cause modelling - **CCPS Guidelines for Hazard Evaluation Procedures** (3rd ed.) - **ISO 17776** — major-accident hazard management ## Method 1 — HAZOP Worksheet ```java …

How to install
mdr add equinor/neqsim/neqsim-hazid-fmea-eta-fta@sha256:34f5f54aca296926The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
