For the transport of explosive substances or objects to or from the public highway, the employer draws up a document which, taking into account the nature of the load, indicates precisely the authorised routes within the site and analyses the possible domino effects between the convoy and each installation. This document is added to the safety file mentioned in article R. 4462-34.
Upon entering the site, these transports are checked to ensure that the load complies with the data in the document provided for in the first paragraph and to ensure that there are no anomalies likely to introduce an increased risk during internal traffic.
