PRACTICAL ASPECTS OF IMPROPER INSTALLATION AND MAINTENANCE OF EQUIPMENT INTENDED TO BE USED IN POTENTIALLY EXPLOSIVE AREAS AND RECOMMENDED MEASURES
Abstract
In the evaluation activity of technical equipment intended to be used in potentially explosive atmospheres, by national and international legislation, non-compliant aspects were often reported regarding the choice, installation and maintenance of this explosion-proof equipment. The following main aspects were pointed out: the equipment that was initially chosen and installed appropriately for the specific application but later, over time, improperly maintained; respectively, the situation in which they were inappropriately selected from the beginning for the intended application, by ignoring the existing hazard due to the presence of potentially explosive atmospheres. Both reported situations could induce major hazards in the short or long-term operating conditions of the respective equipment, which can become an effective source of ignition of the atmospheres endangered by the presence of explosive mixtures within the flammability limits. The work is intended to be a warning signal regarding the negative aspects detected during the evaluation activity and also provides solutions for their remedy.
