Identification
Official name, class and classification code, packing group, labels, tunnel code and transport category. The Kemler number is decoded into plain words — not left as a code to remember.

🔎 Orange plate 33: highly flammable liquid (flash point < 23 °C)
✅ USE
- Dry chemical powder, CO₂, water spray
- Alcohol-resistant foam
⛔ DO NOT USE
- Solid water jet — spreads the fire
Real example. Every sheet also carries main hazards, tactical approach, immediate actions, PPE and first aid — and, for substances toxic by inhalation, the isolation distances.
What each sheet gives you
Extinguishing agent
What to use and — the part that matters most — what never to use. Water on a substance that reacts with water is flagged in red, on its own line.
Isolation distances
For substances toxic by inhalation: distance to isolate and downwind protective action, split by small and large spill, day and night. Metric only.
Hazards and actions
Main hazards, tactical approach and immediate actions, anchored in the written instructions of ADR 5.4.3 — the official text, not a paraphrase.
PPE and first aid
The protective equipment for the intervention, kept separate from the equipment carried on board the transport unit. First aid, general and specific to the substance.
Multiple Table A entries
One UN number can have several rows in Table A and they are not equivalent: for UN1863, packing group III changes the Kemler number from 33 to 30. The sheet shows every row and lets you pick the right one.
Why it holds up in the field
Works with no network
Install it once and it runs offline. Tunnels, industrial estates, back roads — the places where an incident actually happens are the places with no signal.
Instant and deterministic
No AI and no waiting. It is a lookup: the number goes in, the sheet comes out. The same UN number always returns the same sheet — no invented answers.
2347 UN numbers
The whole of Table A of ADR 2025 — 2347 UN numbers across 2897 entries — plus the ERG 2024 guides. In Portuguese and Spanish.
