Area classification is not a copy and paste process

Abstract

When designing the electrical installations of an industry that processes flammable products, it is necessary to know where the classified locations are. These locations are identified in drawings in order to orientate the specification of adequate electrical and electronic equipment. This paper will show why the figures' copy-and-paste practice does not guarantee a cost effective installation and will present comparisons between gas dispersions models aiming to help professionals to perform a reliable hazardous area classification study.
