# 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.
