The type of protection flameproof enclosure consists in placing the parts that can ignite an explosive atmosphere into an enclosure that can withstand an internal explosion and it prevents the transmission of the explosion effects (hot gases, flames, incandescent particles etc.) capable of ignition to the external explosive atmosphere in which the equipment is placed. The purpose of the paper is to underline some specific situations that can occur during the tests in explosive mixtures needed to verify the charact...

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 explosio...

Many processes involving dusts, suspended or accumulated, have the potential to lead to fire, explosion or decomposition in the presence of oxygen and an ignition source. The risk of dust explosions increases as more and more products take the form of dusts or require the use of dusts during manufacture. In spite of extensive research and development to prevent and mitigate dust explosions in the process industries, this phenomenon continues to represent a constant hazard to industries including manufacturing, usi...

Many operations with flammable liquids produce flammable atmospheres by evaporation of the liquid being handled. In some circumstances, the flammable atmosphere is not due to the liquid being handled but due to residues of volatile liquid or vapor from earlier operations with the same equipment as is often the case with diesel fuel handling. This paper highlights some aspects regarding the danger of fires and explosions in the transport, storage and distribution of diesel fuel starting from the investigation of th...

In industrial plants many types of combustible dusts are generated, processed, handled and stored. When ignited, they can burn rapidly and with a considerable explosion force, when mixed with air in proper proportions. This is the reason why adequate precautions have to be adopted, to ensure that all equipment and protective systems are appropriately protected so that the security level from these installations to be high. The establishment and implementation of protection measures is primarily aimed at preventing...
