§ Mr. Simmonds
asked the Home Secretary whether the scheme for the more frequent sounding of the public air-raid warning signal announced by him on 10th September, is now in operation?
§ Mr. H. Morrison
The statement of 10th September indicated that the public warning by siren should be treated as an alert and that this interpretation of the warning would remove the main practical disadvantages of sounding the siren freely. It must take some time to secure the general recognition of the siren as an alert and not an alarm and to make arrangements for local alarms to be sounded in industrial establishments and elsewhere. Active steps are, however, being taken to achieve these purposes.
