(41ab) A Revisiting of the PSM Approach Applied to the Assets of the Electrical System / Releitura Da Abordagem Do PSM Aplicada Para Ativos Do Sistema Elétrico

The Electrical Power Systems and Electrical Industrial Systems are vital parts
of industrial plants and production processes in many different areas. As evidenced in
several catastrophic occurrences in industrial plants around the world, failures in
electrical systems are major causers of potential losses, either directly or indirectly as
initiators of unwanted events that cause multiple fatalities, severe environmental
events, major production interruptions, with the respective financial losses, imputing
risks to the sustainability of companies. The occupational safety approach does not
establish barriers to prevent or mitigate some of these types of events. Thus, how to
enable a process safety viewpoint to the events with electrical system assets? This
paper aims to provide a review of process safety management applied to the events
with electrical system assets, as well as to propose the application of the RBPS - Risk-
Based Process Safety elements, through the development of normative standards, in
order to establish preventive and mitigating barriers against the unwanted events with
catastrophic potential.
