What were the causes?

The outer insulation of the cabling was damaged.

The cable insulation had deteriorated due to age and weathering, exposing the live wire.

The location of the cable was such that it was not easily accessed for detailed visual inspection.

Actions

  • Visual inspection of all electrical cables for early signs of ageing and weathering, particularly in difficult to see areas.

IMCA notes that neglected exposed mains cabling is a surprisingly common high potential issue, in an area – electrical safety – that ought to be a good deal more tightly controlled.
