Chemical compatibility
The substance is compared against every neighbour in the zone on CLP hazard classes and the reactivity data in section 10 of each safety data sheet.
ICPE compliance · France
ChemTrack tests each proposed storage decision against chemical compatibility, physical separation and zone capacity, then builds the DREAL documentation from the same record. Made for the roughly 20,000 mid-size ICPE sites that still run their chemical inventory on spreadsheets.
The problem
A mid-size ICPE site keeps its chemical inventory in a spreadsheet and its safety data sheets in a binder. Compatibility is checked from memory, at the moment a drum is set down. Inspection files are rebuilt by hand, from scattered sources, in the weeks before a DREAL visit.
Three post-Lubrizol arrêtés have since raised the documentation standard: the September 2020 action plan, the September 2021 prescriptions for flammable liquid storage, and the June 2025 text for rubrique 1510 warehouses, in force since 1 January 2026. Inspection pressure rose with it. The manual process has not moved, and the gap between what is required and what a single HSE manager can produce by hand keeps widening.

Where we fit
The top of the French market is covered. Upper-tier Seveso sites run enterprise EHS suites with six-figure implementations. Large industrial groups buy specialist platforms with long deployments and dedicated EHS staff.
Below them sit roughly 20,000 mid-size ICPE facilities with one HSE manager, a spreadsheet, and the same regulator. No product is built for them. That is the ring ChemTrack is built for — a segment to convert, not a share to win.
How it works
When an operator registers a placement, the rule engine runs the proposed substance against everything already in the zone and in the zones next to it. The verdict comes back at the point of action, with the rule that produced it.
The engine is deterministic. It reads four public sources — the safety data sheet, INRS classifications, INERIS technical guidance, and the prescriptions attached to the zone's rubrique — and applies them as explicit rules. Nothing is predicted. Every verdict traces to a rule, and every rule traces to a source an inspector can open.
The substance is compared against every neighbour in the zone on CLP hazard classes and the reactivity data in section 10 of each safety data sheet.
Minimum distances and retention requirements are applied per hazard category, following the prescriptions attached to the zone's rubrique.
The projected volume is measured against the authorised quantity for the zone and for the hazard class it belongs to.
Calibrated conservatively. A false positive costs a review. A false negative costs an incident. A safe placement may be sent to the HSE manager for confirmation. An unsafe one is never quietly approved.
Edge cases are flagged, not guessed. Incomplete safety data sheets, unusual hazard combinations and conflicting classification sources go to human review with the conflict shown, rather than being resolved automatically.
Outcome 01
All three checks pass. The placement proceeds and the entry goes to the register with the rules that cleared it.
Outcome 02
A rule is close to its limit, or the zone is filling. The operator continues only after the HSE manager confirms.
Outcome 03
An incompatibility or an authorised quantity is breached. The placement stops and the nearest compliant zone is offered.
Outcome 04
The safety data sheet is incomplete, or two sources disagree. The engine does not resolve it. It shows the conflict.
The rules are real. The site is invented — six substances, five zones. On your facility the same engine runs against the substances and zones you declare.
Architecture
A rule base that holds what the law requires, an engine that applies it to a single proposed placement, and a register that keeps the proof. Each layer feeds the next, and every answer can be traced back through all three.
Layer 01
Hazard classes, incompatibility pairs, separation distances and zone prescriptions, written down as rules a machine can execute. Built from public sources, not from a vendor's private judgement.
Layer 02
Three checks run against every proposed placement: chemical compatibility, physical separation, zone capacity. Deterministic — no scoring, no inference, no probability attached to a hazard.
Layer 03
Substance, zone, rules applied, sources read, decision, time, operator — written once and never rewritten. The DREAL pack is generated from that record rather than assembled from memory.
The life of a single placement
The substance enters the register with its safety data sheet and CLP class.
The operator picks a zone on a tablet, while the drum is still on the forklift.
Three rules run against what the zone already holds and how full it is.
Cleared, review or blocked, with the rule and the source that produced it.
A blocked placement returns the nearest compliant zone, not a dead end.
The decision and its evidence go to the register. The report is already written.
The platform
The operator needs a yes or a no while standing in the aisle. The HSE manager needs an inspection file that holds up. Both read from the same register, so the report is never reconstructed after the fact — it is already there.
| Substance | Zone | Rule | Raised | Status |
|---|---|---|---|---|
| Acetone · IBC 067 | B-2 · Oxidisers | CLP-INC-01 | 2 h ago | Blocked |
| Sulfuric acid 96% · drum 214 | D-4 · Bases | SEP-01 | 6 h ago | Review |
| Toluene · pallet 31 | A-1 · Flammables | CAP-02 | Yesterday | Review |
The operator opens the placement view on a warehouse tablet, scans the container, picks the zone. The verdict returns with the rule and the substances that triggered it. A blocked placement offers the nearest compliant zone rather than a dead end.
Substance, zone, rules applied, sources consulted, decision, timestamp, user. That log is the audit trail the DREAL pack is built from. In the MVP the operator view is a responsive web interface, built for tablet use in warehouse conditions. A native application with offline queueing is planned for 2027.
The interface we are building, drawn with sample data. Development runs through H2 2026, with the first pilots at the end of the year.
Four modules
One record per substance: identity and CAS number, CLP classification, quantity, zone, arrival date, supplier, and the source safety data sheet. Every change is versioned with a timestamp and a user. The spreadsheet and the binder stop being the source of truth.
The three checks run against the zone and its neighbours the moment a placement is registered. The verdict names the rule, the substances involved, and the sources consulted — a record an inspector can follow without an explanation from us.
Inventories by hazard class and by zone, compatibility matrices, zoning maps with capacity against regulatory limits, rubrique threshold calculations, and a compliance summary with verification timestamps — generated from the live register, formatted for the arrêtés of 2020, 2021 and 2025.
A zone approaching its capacity threshold for a hazard class. An unresolved flag. A substance past its expiry date. A regulatory update affecting one of the site's rubriques. Alerts reach the HSE manager in the dashboard and by email, with escalation rules the manager sets.
Data
A compliance register holds what a site stores, in what quantity and where. That is sensitive industrial data, and it is handled as such: hosted in the European Union, isolated per client, encrypted at rest and in transit, and written to an audit trail that cannot be edited after the fact.
Why ChemTrack
The tools that exist are built for the top of the market, and they behave like it: enterprise pricing, long deployments, and a record written after the fact. ChemTrack is built the other way round.
Enterprise EHS suites are scoped and priced for upper-tier Seveso sites. Below them sit roughly 20,000 mid-size ICPE facilities running on spreadsheets. That segment is the whole point.
Most systems record what was stored. ChemTrack tests the decision at the point of action, while the pallet is still on the forklift and the mistake still costs nothing.
No scoring, no model confidence, no probability attached to a hazard. Every verdict maps to a written rule and the public source it came from, which is what an inspector asks for.
A safe placement may be sent to review. An unsafe one is never quietly approved. Where the sources conflict, the conflict is shown rather than resolved by guesswork.
Compliance documentation is not a file assembled the week the inspector calls. It is the by-product of checks that have already been made, logged as they happened.
Built on the rubriques, the arrêtés and the format the DREAL expects, rather than translated from a compliance model designed for another country.
Who it is for
The single site proves the product and pays for it. Multi-site groups carry the scale. Everything below is what we are building towards, in that order.
Sites under autorisation or enregistrement with a real chemical inventory, an HSE manager wearing several hats, and no software between the operator and the shelf.
Several ICPE sites under one roof of responsibility, each with its own rubriques, its own zones and its own way of keeping the record.
The people who prepare mid-size sites for inspection today, by hand, and who carry the same compliance risk on behalf of their clients.
Our purpose
A chemical accident begins as an ordinary decision, taken quickly, by someone who had no way to check. ChemTrack exists to give that person the answer before the drum goes down.
France first · the wider European ICPE framework as the longer horizon
The founders
ChemTrack sits where hazard knowledge, systematic risk control and audited IT delivery meet. Two founders, one first engineering hire planned for the third quarter of 2026.
B.Tech in pure and applied chemistry. Over twenty years across security operations, risk management, financial services and logistics in West Africa and Europe, including a decade leading a security services company of more than 2,500 personnel.
