§ Mr. Anderson
asked the Minister of Power if, having regard to the explosion which occurred at the Llwyni Farm Substation, Abergavenny, on 21st February, 1969, he is satisfied that adequate provision is made for the safety of the public who may be in the vicinity of the 150 outdoor-type switchboards that are in service in South Wales; and if he will make a statement.
§ Mr. Freeson
Yes. The explosion was caused by the failure of insulation in 11 kV switchgear. I have consulted the Electricity Council which agrees with the Chairman of the South Wales Electricity Board that the hazard to the public is minimal.
