§ Sir G. Foxasked the Lord Privy Seal what warning provision is made in advance to ensure that in case of a sudden air-raid no confusion arises as a result of experimental tests of sirens which have accustomed the public to hearing these warnings and taking no action thereupon?
§ Sir J. AndersonEvery effort is made to warn the public in advance when practice tests of sirens are to be made. In the event of a sudden emergency the public would be notified by means of broadcast announcements and other means that the warning system was in operation.
