Formed in 1952 under the British colonial government of Hong Kong (CAS Ordinance) and modelled after Civil Aid agencies in the United Kingdom.

As well, a youth section, CAS Cadet Corps, adds 3,232 volunteers to the regular 3,634 force.

The concept was introduced during British rule, an organisation also found in Britain.

A dedicated Civil Aid Service rescue training centre, with indoor and outdoor training areas, was opened by the governor on 15 November 1953 at Hawthorn Road, Happy Valley.[1]

The CAS used to be headquartered at Caroline Hill Road in Causeway Bay. It moved to Yau Ma Tei in 2006. The six-storey former CAS Headquarters is slated for demolition by the government.[2]
