Accessible technical solution for normal construction apparatus usage in Ex classified areas

摘要

In this work is highlighted an undesirable penury state regarding eligible technical equipment for use in Ex classified areas. This fact competed with the negative dynamic of material possibilities leads to an apparent lack of interest regarding protection to explosion. As a solution to the identified problem, the authors propose the use of normal construction technical equipment adapted according to prescriptions of "pz" pressurized enclosure protection type. This intercession presents a good estimated level of tolerance to customer and will lead to the decrease of explosion risk level due to technical equipment and lower acquisition, maintenance and repair specific costs.
