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. The sheet opens on the worst case and only leaves it if you say what you are looking at — for chlorine, a rail tank car is 1,000 m and small cylinders are 150 m.
• 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.
• Appearance, odour and incompatibilities — from the NIOSH Pocket Guide, for the 362 UN numbers whose substance is identified: how it looks, how it smells, and what must never touch it. It is how the crew confirms on scene that this really is the substance on the transport document. On generic entries it does not appear, and that is honest.

More than the sheet

• The profile changes the sheet — firefighter, police, ambulance, driver. Each person picks theirs once and the sheet reorders itself: the firefighter sees the extinguishing agent first, the police officer sees the distances first. Each profile gets its own action badge for the first sixty seconds.
• My position — one button gives the coordinates and the MGRS with the accuracy shown next to them, and sends them by SMS or WhatsApp. The position never leaves the phone on its own and never reaches us.
• My area — which Seveso establishments sit in your municipality, asked at the depot and not at the incident: 2,358 sites in Portugal, Spain and France, from the official public registers. Part of specialist access.
• Built for a phone held in gloves — high contrast for reading in the sun, cards that open to the full official text, jumping between the UN numbers of a mixed load without typing again, and sending the whole sheet to the incident commander.

Training is included

One 90-second scenario a day. An app you only open on the worst day of the year has already been deleted by the time that day arrives. The scenario is derived from the date, so everyone who opens MYDG2SAVE today gets the same one — no server and no account involved — and it trains the gesture rather than the theory: where to stop the vehicle, what the orange plate says before you look anything up, opening the sheet by typing the number, telling the sheet what is in front of you, and whether water can be used.

No new content, so it cannot go stale. The exercise is built from the same sheet the app serves in an emergency. A hand-written question bank goes out of date in silence and one day teaches the old number; this one cannot contradict the sheet, because it is the sheet. A twelve-step guided first run teaches how to read the sheet, not just how to reach it, and can be repeated whenever new people arrive.

Results stay on the phone. No ranking and no report to the employer: a league table turns training into a performance review, and then people stop training. And the emergency always wins — typing anything into the search box cancels the exercise on the spot.

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 and the NIOSH Pocket Guide, in Portuguese, Spanish, French and English.

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.

Where the code goes: inside the app. Install MYDG2SAVE — App Store (iPhone) or Google Play (Android) — open the menu at the top and, under Account, tap “I already have a licence”. Enter the e-mail and the code, and you are in. It also works on a computer, at app.mydg.shop/2save.

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.
