Resumo
There have been several flood events in our country, notably in the Southeast Region, in
the last decades, where the public management faces natural causes, such as storms with
heavy rains and winds, causing landslides, flooding in urban centers and, consequently,
losses. According to Leveson (2019, p. 34): CAST (Causal Analysis Based on SystemsTheory) is a structured technique to analyse accident causality from a systems
perspective. CAST is an analysis method, not an investigation technique. But performing
the CAST analysis as the investigation proceeds will assist in identifying what questions
need to be answered and what information needs to be gathered during the investigation
in order to create a comprehensive explanation as to why the loss occurred and to help
formulate recommendations to prevent related accidents in the future. The CAST, as an
approach after the occurrence, links to STPA (System-Theoretic Process Analysis)
methodology (prior to the accident). This aims to analyse an event – which may or may
not result in an accident – the way that its parts, acting systemically, can be studied,
reaching the confrontation of the insecure condition(s) through effective actions. The
/CAST methodology was herein applied to the event “Floods in the summer of 2020 in
Piracicaba/SP”. This event provides analysis completeness, according to this model.
Several intervening factors are sought in this study; the accident considered here are the
floods that generated material losses in the city: e.g. destroyed buildings, streets and
houses flooded, leading to losses.
