HC Deb 13 February 1941 vol 368 c1509
72. Mr. James Hall

asked the Home Secretary whether he has considered the need for the covering of the floor below the roof by a thin layer of concrete in warehouses constructed of wooden floors so as to reduce the destructibility of incendiary bombs; and is he prepared to put this precaution into operation?

Mr. Mabane

Protective measures of the nature referred to have been explained in a handbook, "Incendiary Bombs and Fire Precautions," which can be obtained from the Stationery Office. My right hon. Friend is advised, however, that the layer of concrete sufficient to provide against penetration of an incendiary bomb would be of such a thickness that this precaution would not always be practicable. He would hesitate, therefore, to make it a general requirement.
