The thesaurus provides a list of emergency management terms, related terms and scope notes primarily based on the definitions in the Emergency Management Glossary and some by specialists. These terms include those likely to be used by all services in the area, some from specialist fields that are commonly used in other areas but not those relating to specific areas of particular emergency services. This is Manual 4 (Compiled by staff of the Emergency Management Information Centre, 1998, ISBN 0 642 58810 4) in the Australian Emergency Manual Series.
