Basically it establishes the criteria that if you wish to offer for transport, handle, or import dangerous goods that are the most dangerous of dangerous goods, basically those that have reach, those that can cause problems outside of just the accident itself and you get into all kinds of different chemicals, biological, radioactive, nuclear, explosives all of those are required to have an emergency response assistance plan.
En gros, il établit les critères à respecter si quelqu'un veut transporter, manipuler ou importer des marchandises parmi les plus dangereuses, c'est-à-dire celles susceptibles de causer des problèmes allant bien au-delà de l'accident lui-même. Je pense à différentes substances chimiques, biologiques, radioactives, nucléaires ou explosives.
