MYDG2SAVE

MYDG2SAVE — emergency intervention sheets by UN number, offline

The UN number is already there, on the orange plate. Type it into MYDG2SAVE and the crew gets, in one second and with no network, what it needs on arrival: the main hazards, which extinguishing agent to use — and which one never to use — isolation distances, PPE and first aid.

This licence covers company use: in-house fire brigades at refineries and chemical plants, ADR transport operators, warehouses and safety teams that keep dangerous goods on site. Public emergency services — fire and rescue, civil protection, police, Guardia Civil and GNR, medical emergency — are licensed per entity and not per person: ask us for a quote instead.

What each sheet gives you

• 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.
• Extinguishing agent — what to use and, above all, 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.
• PPE and first aid — the equipment for the intervention, kept separate from the equipment carried on board the transport unit.
• Multiple Table A entries — one UN number can have several rows, and they are not equivalent: for UN 1863, 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

It 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.

It is instant and deterministic. No AI and no waiting: the number goes in, the sheet comes out. The same UN number always returns the same sheet, so there are no invented answers.

It covers the whole of Table A — 2,347 UN numbers across 2,897 entries of ADR 2025, plus the ERG 2024 guides, in Portuguese and Spanish.

The licence

One licence, one person. Choose the quantity: eight people on the team, eight licences. We never ask you for their names — you get one code, you hand it to whoever you choose, and each of them enrols with their own e-mail, on their own phone. We never know who you gave it to.

The licence runs for one year from the purchase date. It is not a recurring subscription: nothing renews on its own and nothing is charged again without you asking. Your code is sent by e-mail as soon as the order is confirmed.

Up to 25 people you can buy here. Above that the price stops being per head — ask us for a quote.

The data is kept current as the ADR is revised, and our DGSA team answers what the sheet cannot.

MYDG2SAVE is a decision-support tool. It does not replace your standard operating procedures, the transport document, the written instructions carried on the vehicle, or the authority of the incident commander on scene. Always confirm the UN number on the orange plate.
