In particular, Vega Engineering specializes in the following activities: - analysis of the customer's production processes, - classification of places with danger of explosion , - assessment of the risk of explosion , - design and construction management of newelectrical systems in areas with danger of explosion , - adaptation, expansion and modification of electrical systems in ATEX areas . As regards the classification of areas in which explosive atmospheres may form , Article 293 obliges the employer to divide (classify) the workplaces into specific areas, in accordance with Annex XLIX, based on the frequency and duration of the presence of explosive atmospheres. We recall below the definitions of the " ATEX Zones " with which the environments are classified. Explosive atmosphere caused by the presence of a mixture of flammable gases, vapors or mists Zone 0: Area in which an explosive atmosphere consisting of a mixture of air and flammable substances in the form of gas, vapor or fog is present permanently or for long periods or frequently Zone 1: Area in which the formation of an atmosphere explosive , consisting of a mixture of air and flammable substances in the form of gas, vapor or mist, is likely to occur occasionally during normal activities Zone 2: Area in which the formation of an explosive atmosphere is not likely during normal activities consisting of a mixture of air and flammable substances in the form of gas, vapor or mist or, if it occurs, is only of short duration Explosive atmosphere caused by combustible dusts Zone 20: Area in which an explosive atmosphere in the form of a cloud of combustible dust in the air is present permanently or for long periods or frequently Zone 21: Area in which the formation of an explosive atmosphere under form of combustible dust cloud, is likely to occur occasionally during normal activities Zone 22: Area in which during normal activities is not likely the formation of a ' explosive atmosphere in the form of a cloud of combustible dust , or, if you verify, is only of short duration For theclassification of areas with risk of explosion , reference can be made to the harmonized technical standards relating to specific sectors, including: - CEI EN 60079-10-1 ( CEI 31-87 ) “Explosive atmospheres - Part 10-1: Classification of places. Explosive atmospheres due to the presence of gas " - CEI EN 60079-10-2 ( CEI 31-88 ) " Explosive atmospheres - Part 10-2: Classification of places. Explosive atmospheres due to the presence of combustible dusts " . Based on this classification of areas with risk of explosion , all appliances and electrical systems installed within these ATEX zonesthey must be compatible, in order to make it impossible to ignite the explosive atmosphere . Vega Engineering technicians have the skills and many years of experience in the classification of places with danger of explosion , pursuant to Legislative Decree 81/08 and the current technical regulations ( CEI standards ) and in the design of electrical systems in places ATEX .
