“…In analysing such calls to highlight the internal organisation of the parties' actions, we shed light on the "practical oral production" of one of society's institutions (Watson & Sharrock, 1990, p. 25). The meeting between professional operators -who are responsible for dispatching and otherwise managing the services available in productive and logistically efficient ways (e.g., Artman & Waern, 1999;Ikeya, 2003;Normark, 2002) -with lay members of the public, who unlike the operators often have first-hand information of the incident, has drawn some previous research attention. In particular, the opening moves of such conversations have been identified as crucial points in the interaction, bearing in consequential ways on the continuation of the call (e.g., Garcia & Parmer, 1999;Wakin & Zimmerman, 1999) and, therefore, on the potential success of rescue operations.…”
