This paper addresses the learning process related to the
development of interagency operation and its doctrine
resulted from three episodes’ analysis: the hecatomb in
Caraguatatuba, the radiologic accident with cesium-137
in Goiania, and the disaster at the mountainous region
in Rio de Janeiro. The literature review and documental
analysis carried out in this work intend to obtain
teachings and to shed light on a time gap previous from
the 1st edition of the “Interagency Operations” Manual
(BRASIL, 2012a), published by Defense Ministry in 2012.
The results from this study points out problems that
hampered the effectiveness regarding the mobilization
of civil and military institutions in order to resolve the
complex matters faced at the time of the episodes. Thus,
we conclude the necessity of qualification regarding a
better practice of interagency that can be enabled by means
of courses and trainings, in which the future paths of these
operations can be addressed, considering not advisable the
reunion of agencies exclusively during crisis moments.
