HC Deb 29 April 1968 vol 763 c140W
Mr. Speed

asked the Minister of Power if he will list the major accidents that have occurred in electricity sub-stations over the last three years.

Mr. Freeson

It is not easy to define "major". However, over the past three years there have been seven fatal accidents from electrical causes, each involving one fatality, of which two were to members of the public who had gained unauthorised entry to the sub-station and five were to Board staff.
