Air Raid Precautions
Nottingham was the first city in Britain to develop an ARP (Air Raid Precautions) network, and was a model that other cities were to adopt. It was developed because of the foresight of the Chief Constable. The city was divided into zones, controlled by report and control centres with 45 auxiliary fire service stations. A video of Nottingham's Air Raid Precautions can be seen here.
