ASPECTS REGARDING THE RISK OF EXPLOSION IN DEDUSTING SYSTEMS.

The removal and collection of dust particles from the air discharged into the atmosphere by industrial plants processing, transporting and storing dusty materials is an important objective for employers to prevent air pollution according to environmental legislation and employee safety regulations. Where the dust in question is flammable and may generate an explosive atmosphere, measures must be taken to prevent explosion and/or limit the effects of explosion. To this end, proper assessment of the risk of explosions is essential in order to determine the effectiveness of the measures implemented and/or the need to take additional measures. As there is no specific assessment method for the risk of explosions in dust/air explosive atmospheres, various bodies/persons have developed their own more or less comprehensive assessment methods. In the paper are presented some important aspects included in the assessment procedure applied by us for the evaluation of the risk of explosions in dust removal systems with emphasis on the development of laboratory tests to determine the explosive characteristics of explosive air/flammable dust mixtures as well as on the constructive solutions to limit the effects of possible explosions. It highlights the importance of the competence of persons involved in the design, installation, maintenance and inspection of installations regarding the application of standards, guidelines and legislation in the field.
