Cable ladder bonding

Saw this recently on site, there is a bond across every cable ladder joint. I do not believe that this is necessary as this is not an exposed-conductive-part or an extraneous-conductive-part. Am I right?

  • Something to do with gas and sparks perhaps? My father worked on the Isle of Grain oil refinery many years ago during its construction. The early works were disrupted by the 1953 tidal floods of the area. There are interesting reports and photos of the flooded area in the local newspapers in the heritage resource library in Rochester near to the bridge.
