Setup

Zones, separations, classification records and the daily inventory snapshot

Provenance

11 classification records · 10 zones

Every number the engine reports traces back to something entered here. Inventory arrives as a daily snapshot, not a live feed, which is how these sites actually run. Substance classification is derived from CLP hazard statements by a fixed mapping table — the language model transcribes the safety data sheet and nothing else.

Inventory snapshot

Current: 05 Aug 2026

Upload replaces the whole snapshot. Rows that reference an unknown zone or an unclassified substance are rejected and listed rather than silently dropped — a partial snapshot would understate the aggregate.

SDS extraction

Transcription only

The model reads substance identity and CLP hazard statement codes off the sheet. It does not assign COMAH categories, qualifying quantities or tiers — those come from the mapping table below, so an extraction error surfaces as a wrong quoted code, not a wrong tier.

Separations

12 recorded paths

Distance is the shortest open path between zones; barrier is the most protective structure on that path. Anything not recorded here is treated by the engine as unseparated open ground.

Revise an existing classification

Use this when a safety data sheet is reissued or a supplier corrects a classification. The current position is retained first, so the overview can show what the reclassification alone did to each COMAH threshold with no stock having moved.

Add record manually

Enter the CLP hazard statements printed on the sheet. COMAH categories and storage classes are derived from them by the mapping table — they are not entered by hand, so two records with the same statements can never classify differently.
