Hazards Component Matrix — Template
Purpose
- Capture per‑component hazardous‑area attributes and evidence; support weakest‑link assessment and variant locking.
Table
| Component | Area Class (Zone) | Gas Group | T‑Class | Protection Concept (Ex d/e/tb/other) | Evidence (Doc + lines) | EP Item_ID | Status (Compliant/Partial/RFI) | Notes |
|---|---|---|---|---|---|---|---|---|
| {e.g., Tank Shower Assembly} | {Zone} | {IIB/IIC} | {T3} | {Ex d} | {RepoPath, lines X–Y} | {EP-xxx} | {Status} | {Variant dependency/IP proof/etc.} |
Weakest‑Link
- Compute weakest‑link across components; record class and reason.
