Choosing your refuge room  The picture shows the rooms which should be chosen in typical houses as air raid refuge rooms. A cellar or basement is best of all. In a small house where there is no cellar or basement, the ground floor will be safest, because top floors are always to be avoided on account of the risk from small incendiary bombs. The fewer windows in external walls in a refuge room, the better, and a room of which the window is flanked by a building or strong wall is more advantageous than one having a completely exposed window.

Rendering your refuge room gas-proof  The red arrows in the picture show the danger points at which gas may enter; these must be sealed as instructed below. Cracks in ceilings and walls should be filled in with putty or pasted over with paper. Cracks between floor boards, round the skirting or where pipes pass through the walls should be filled in with pulp made of sodden newspaper. All ventilators and fire-places should be stopped up with paper or rags. Windows should be wedged firmly to keep them tight and the frames sealed round with gummed strip or paper. The cracks round doors should be covered with stout paper and the keyhole plugged. (No.2)

Making a door gas-proof  A carpet or blanket should be fixed over the door opening as shown in the illustration. This should be kept wet and at least twelve inches allowed to trail on the floor. Such an arrangement reduces the risk of entry of gas when the door is opened for use. In addition, if there is a large crevice under the door, a wooden strip covered with felt should be nailed to the floor to make a gas-proof joint. The keyhole and all cracks must be stopped up.
