The description of the organizational framework of emergency Telecommunications requires the definition of the two words, emergency and telecommunication. The first edition of this handbook appeared in 2001 as the handbook on disaster communication. Recent developments required the change to its present title.

Maritime distress and safety communications have traditionally enjoyed privileges such as absolute priority and exemption from fees. The same rules apply for communications with and among aircraft. These privileges do not however apply to emergency Telecommunications on land. Recognition for their applicability in emergency and disaster situations has been recognised only recently, but much still remains to be done.
