The updated ADR agreement introduces new classifications and provisions for the road transport of dangerous goods. Here’s what it means for tank operators, and why a certified wash remains the foundation of every compliant operation.

Every year, the ADR — the international agreement regulating the road transport of dangerous goods — is updated with new provisions: new UN numbers, new packing instructions, updates to special provisions and, on a point that directly concerns anyone operating with tanks, stricter requirements on filling levels and the management of residues during transport.

For transport companies handling tanks, silos and IBCs, every regulatory change translates into a single operational requirement: the tank must arrive at its next load perfectly clean, certified, and free of any trace of the previous product. This isn’t just a matter of paperwork: an unremoved residue can compromise the chemical compatibility of the new load, cause cross-contamination or, in the case of food products, put the end consumer’s safety at risk.

This is where the washing station comes in. A facility like **Clean Wash**, equipped with dedicated paths for the internal washing of tanks, silos and refrigerated vehicles, steam sterilization and hot/cold air drying, allows a vehicle to get back on the road with the correct cleaning documentation and minimal waiting time — an increasingly decisive factor as loading windows narrow to meet the new operational timelines introduced by transport regulations.

Relying on a properly structured washing station, capable of handling food, chemical and powder tanks through separate, trained-staff pathways, is therefore not just a matter of quality: it’s the first line of defence for staying compliant with a regulatory framework that keeps evolving.
