HC Deb 13 June 1972 vol 838 c263W
Mr. Norman Lamont

asked the Minister of Agriculture, Fisheries and Food whether he will make arrangements for the testing of the London flood warning sirens.

Mr. Prior

Yes. The sirens will be sounded at 3 p.m. on Wednesday, 21st June. The purpose of the exercise will be to check that the sirens are functioning properly, to ensure that they are audible throughout the danger area and to familiarise the public with their sound and significance. An extensive publicity exercise is being mounted in co-operation with the Press, radio and television. Copies of a broadsheet explaining the London tidal flood warning system have been placed in the Library.
