Análise preliminar de perigo de incêndios em armazém de açúcar VHP para exportação

Abstract

Given the need to store sugar for marketing throughout the year, sugar storage silos should be designed to meet the and maintain the characteristics of sugar without forgetting the safety of installations and operators. Sugar, being a particle with a small particle size, easily sits in the atmosphere when bustling, creating an explosive atmosphere. Along with this, the storage silos are composed of several elements with the possibility of becoming a source of ignition, such as mat bearings, bucket elevators. The preliminary hazard analysis (PHA) proposed in this study was necessary to identify initially the hazards exposed and suggest measures that minimize the risk of fire. Through PHA they were proposed mitigating measures for each scenario: regular cleaning of equipment, adequacy of the electrical equipment used in the installation, training employees, lightning protection system, regular maintenance, adequacy of moisture parameters and sugar grain size and installation of physical barriers between silo environments. Another finding was that all scenarios had probable frequency and critical severity or catastrophic, classifying risks as "Not tolerable."
