Air raid warden

Air Raid Precautions (ARP) was an organisation in the United Kingdom set up in 1937 dedicated to the protection of civilians from the danger of air raids. It included the Raid Wardens' Service that was to report on bombing incidents. Every local council was responsible for organising ARP wardens, messengers, ambulance drivers, rescue parties and liaison with police and fire brigades.

From 1 September 1939, ARP Wardens enforced the "blackout". Heavy curtains and shutters were required on all private residences, commercial premises, and factories to prevent light escaping and so making them a possible target for enemy bombers to locate their targets. With increased enemy bombing during the Blitz, the ARP services were central in reporting and dealing with bombing incidents. They managed the air raid sirens and ensured people were directed to shelters.

From 1941 the ARP officially changed its title to Civil Defence Service to reflect the wider range of roles it then encompassed. During the war almost 7,000 Civil Defence workers were killed. In all some 1.4 million men and women served as ARP wardens during World War Two. The Civil Defence Service was stood down after the end of the war in Europe on 2 May 1945.

During the First World War Britain was bombed by Zeppelins and Gotha bombers and it was predicted that large-scale aerial bombing of the civilian population would feature prominently in any future war. In 1924 the Committee of Imperial Defence set up a subcommittee to look at what measure could be taken to protect the civil population from aerial attack. The new committee, known as Air Raid Precautions was headed by the then Lord Privy Seal, Sir John Anderson.

For the next ten years this committee looked into issues of new aerial weapons development and the possible impact on civilians. The use of gas attacks in the First World War played heavy on the decisions and protection via gas masks was a core decision taken by the committee. Every single person would need a gas mask which meant nearly 40 million would be required. Together with ideas around the building of air raid shelters, evacuations of people and blackout requirements these were all termed under 'passive air defence'.
