Assessment of Safety Measures in Drying Systems

Abstract

Fire and explosion hazards as well as safety measures encountered in drying processes are presented. Those data were used to work out a simplified layer of protection analysis (called dLOPA). In the developed method, necessary tools based on the matrix concept were presented. It concerns the assessment of an effective ignition source probability and severity of a possible consequence of dust explosion. A step-by-step procedure for dLOPA analysis is presented. This method may find application in risk assessment for workers exposed to explosive atmosphere (ATEX Directives).
