HC Deb 07 December 1939 vol 355 c843W
Mr. Gallacher

asked the Home Secretary whether the ban has yet been lifted on the rot-proofing of sandbags with a copper solution by municipal authorities?

Sir J. Anderson

Local authorities were advised in a circular of the 20th October last to treat sandbag revetments against rot; and one of the methods recommended was the use of an organic copper salt.
