The video above explains the guidelines which were issued to keep Anderson shelters as comfortable as possible in the winter. Close up shot of a cartoon showing 'wailing winnie' - the air raid siren.

Anderson shelters – named after wartime politician Sir John Anderson - were designed in 1938 to accommodate six people during German air raids. Though some bomb shelters were made from brick, a typical Anderson shelter comprised of six corrugated steel panels with flat panels bolted on to form the side and end panels.Families were provided with the materials and were expected to construct them from a set of instructions.

Many families virtually took up residence in their shelters when raids became frequent but, being far from the last word in comfort, they were reluctant to do so. Anyone taller than 6ft would have been unable to stand up in one and, during the winter months, they could be exceptionally cold inside. Though they were not designed to withstand a direct hit, Anderson shelters were effective at saving lives and preventing injuries from blast waves caused by exploding bombs in the vicinity.
