§ Mr. Windsorasked the Home Secretary whether his attention has been drawn to the confusion and uncertainty in the Hull district regarding air-raid warnings; whether he is aware that the knowledge that air-raid precautions bodies have received the first light warning soon becomes public thus creating genera] apprehension, even in the absence of sound warnings which are not given until the appearance of the second signal light; and whether he will take steps to ensure that, whatever signal lights are received, the siren system will be so utilised as to result in the minimum of public anxiety?
§ Sir J. AndersonIn the Hull area, as elsewhere throughout the country, the public warning sirens are sounded when an air-raid warning message is received originating from the Air Officer Commanding-in-Chief, Fighter Command. The preliminary caution message should 1281W not be made public. In very many cases this message is not followed by the air-raid warning message, but is cancelled. My right hon. Friend is about to remind all local air-raid precautions authorities of the need of preserving the confidential character of the preliminary caution message.
