The Civil Aid Service (Chinese: 民眾安全服務隊) or CAS (民安隊) in short is a civil organisation that assists in a variety of auxiliary emergency roles, including search and rescue operations in Hong Kong:

  • providing support to the government regular emergency forces on counter disaster activities, mountain search and rescue, flood rescue, countryside fire protection duties;
  • providing crowd control and management services in major public functions;
  • patrolling country parks and hiking trails and to assist people in need of help;
  • staging performances to enhance public attention on major campaigns or activities organised by government departments and non-government organisations;
  • providing training activities and professional services on mountain safety/rescue for government departments and non-government organisations.

CAS is funded by the Hong Kong Government and its members wear uniforms.
