The ADR chemical risk pictograms are based on those of the Globally Harmonized System of Classification and Labeling of Chemicals GHS:.

The safety advisor is a transportation professional, expert and responsible for compliance with the agreements: ADR (road), RID (rail) or ADN "ADN (transport by waterway)") (river) in a company that transports or stores dangerous goods.[5] These professionals achieve their accreditation through an exam. There are different specialties: explosives, gases, radioactive material, hydrocarbons and other dangerous cargoes.

In 1993, a team of chemical experts and experienced fire chiefs from seven European countries began to develop CEFIC's "Emergency Response Intervention Sheets" (known by their acronym in English as ERIC Cards or ERIC CARDS).

The sheets were prepared by grouping all substances according to their Hazard Identification Number ADR (HIN), which provides information on the risk of the product, and the UK Emergency Action Codes (EAC).

The ERIC sheets were first published (in English) in November 1995 and were subsequently revised and updated in January 1998 and May 1999. In 2003 they were adapted to the 2003 version of the ADR and to the UK Hazchem list number 10 (1999) for Emergency Action Codes. Since then, sheets have been included for all Class 1 ADR (explosive materials and objects) and Class 7 ADR (radioactive materials) substances. This latest major revision and extension of the ERIC Sheets has been financially supported (Ref SUB-B27020B-E3-ERICARDS-2002-S07.14176) by the European Commission - Directorate General for Energy and Transport.

The current version of the ERIC sheets has been adapted to ADR 2005 and the UK Emergency Action Code, Listing 2004 (adapted to new or amended entries in ADR 2005).

There are also similar agreements regulating the conditions for the transport of dangerous goods by rail (RID")), by sea (IMDG Code), by rivers and lakes (ADN Agreement "ADN (transport by navigable waterway)")) and by air (ICAO).

The ADR agreement defines dangerous goods as:.

The agreement regulates the packaging, transportation, documentation and other aspects of road transport of dangerous goods, including their loading, unloading and storage, whether the transport is carried out between several countries or within the territory of a single one. An important aspect is the determination of the obligations and responsibilities of each of the participants in the operations in order to try to avoid damage to people and things, as well as protect the environment.

The regulations contain a detailed list with headings for most of the goods considered dangerous (coded according to a number established by the UN) and the regulatory requirements that apply to each case. The regulation affects both those directly involved in the transportation and the manufacturers of elements and materials related to the transportation, packaging and handling of dangerous goods.

The vehicles, called "transport units" in Annex B, must have an approval certificate, or "ADR certificate", that certifies compliance with the aforementioned Annex B and that they are authorized for the transport of dangerous goods by road. The certificate requires that the vehicle have a shielded electrical installation, independent battery disconnector, fire extinguishers...[4]​.

Transport units must be provided with the characteristic orange signal. These panels are located at the front and rear of the vehicle; They are made up of two parts:

If the vehicle transports several dangerous goods, compatible with each other, the orange panel does not indicate any number. Tank vehicles transporting dangerous goods must carry the danger labels corresponding to the goods.
