§ 34. Mr. Dolandasked the Home Secretary whether his attention has been called to mechanical devices for the protection of shop windows from the effect of blast in air raids; whether the resistance of any such devices to blast from high explosives has been tested officially or otherwise; and whether he can recommend their use, or will he advise shopkeepers of methods whereby the safety of the public from splintered plate-glass can be in any way safeguarded?
§ Sir J. AndersonThe value of devices of the kind to which my hon. Friend refers has been under investigation, but the results so far obtained disclose no grounds for thinking that these devices are likely to prove as useful as the methods of protection recommended in the official publications already issued.
