Abstract

This work aims to identify risk possibility events with dangers and environmental aspects, whose occurrences could result in unwanted damage to people, plants, environmental and company’s image during preparation, development, implementation and operation of a drying air heating system that will be mounted at Baldo S.A in Prudentópolis-PR This analysis involves risk identification present during system operation using: FMECA (Failure Mode, Effects and Criticality Analysis), FTA (Fault Tree Analysis), ETA (Event Tree Analysis), and CNEA (Causal Network Event Analysis) which allowed identifying main problems, causes, detection modes, and effects of failures that could happen during system operation, moreover, are given some recommendations that serve with preventive type of barriers such as the type of contingencies to minimize risk events during system lifetime. Keywords: Risk analysis, two-phase thermosyphon, air heating system.
