+# Fusion Plating — Chrome Plating Process Pack
+
+Part of the **Fusion Plating** product family by Nexa Systems Inc.
+
+Data-only add-on for the `fusion_plating` core module. Seeds chrome-plating
+process types and their bath chemistry parameter schemas.
+
+## What it ships
+
+### Process types
+| Code | Name | Chemistry |
+|---|---|---|
+| `CR_HARD_HEX` | Hard Chrome — Hexavalent (Cr(VI)) | Cr(VI) |
+| `CR_DEC_HEX`  | Decorative Chrome — Hexavalent (Cr(VI)) | Cr(VI) |
+| `CR_HARD_TRI` | Hard Chrome — Trivalent (Cr(III)) | Cr(III) |
+| `CR_DEC_TRI`  | Decorative Chrome — Trivalent (Cr(III)) | Cr(III) |
+| `CR_STRIKE`   | Chrome Strike | Cr(VI) |
+
+Hex-chrome variants are colour-tagged red, trivalent variants green, and
+the strike grey. All five live under the core's **Plating** category.
+
+### Bath parameters
+CrO3, trivalent Cr, H2SO4, CrO3:H2SO4 ratio, bath temperature, current
+density, iron/copper contamination, mist suppressant level, and voltage.
+
+## Hazard awareness
+
+Hexavalent chromium is a **confirmed human carcinogen** (IARC Group 1,
+NTP Known Human Carcinogen, Ontario Reg. 833 designated substance). The
+`hazard_notes` field on every hex-chrome record flags:
+
+- Ontario Reg. 833 ceiling limit 0.05 mg/m³ as Cr(VI)
+- Mandatory mist suppression and medical surveillance
+- Toronto Ch. 681 sewer limits (Cr(VI) 2 mg/L, total Cr 4 mg/L)
+- NPRI Part 1B reporting, CEPA Schedule 1 listing
+- No storm sewer discharge (storm limit 0.0008 mg/L Cr(VI))
+- Industry transition toward trivalent chrome where part specs allow
+
+Trivalent variants carry a lighter hazard note but still fall under the
+Toronto total-chromium discharge limits.
+
+## Install
+
+Requires: `fusion_plating` (core).
+
+```bash
+docker exec odoo-dev-app odoo -d fusion-dev -i fusion_plating_process_chrome --stop-after-init
+```
+
+All records load with `noupdate="1"`, so shop overrides survive upgrades.
