It is imperative also to switch off all lights before attempting to open or close a window, if this necessitates drawing the blinds.
These regulations apply to all rooms occupied, including bathrooms.

I attended the Hippodrome in London, walking through the darkness escorted by a friend. The show was pretty much with reference to the war. I was attracted by the notice at the bottom of the program, which is copied below.
Arrangements have been made that warning of a threatened air raid will be communicated by the Military Authorities to this theatre.
On receipt of any such warning the audience will be informed, with a view to enable persons who may wish to proceed home, to do so.
The warning will be communicated, so far as possible, at least 20 minutes before any actual attack can take place. There will, therefore, be no cause for alarm or undue haste.
Those who decide to leave are warned not to loiter about the streets, and if bombardment or gunfire commences before they reach home, they should at once take cover.
By order of The Commissioner of Police of the Metropolis.
