Abstract (EN):
Programmed maintenance is an essential part of safety management in high risk industries
such as oil refineries and their life cycle. Maintenance turnaround tasks are diverse and constitute
an exceptional universe of risks. In this article we intend to discuss if during maintenance turnarounds
there is an increase of undesired events and human factor role. Maintenance activities usually represent
an increase in accidents and incidents frequency. Accidents can have origin in a series of causes amongst
human factor, being human error the most unpredictable. Considering this, we suggest that effective safety
management depends on a comprehensive risk assessment that should integrate an assessment of workers
perceived risk. When integrated in a human risk factor management program, it could allow determining
measures specifically focused on workers, enhancing their risk perception, hence safe behaviour
and aid on diminishing the elevated accident frequency preceded by human failure during maintenance
turnarounds.
