This explosion protection method employs a procedure to maintain internal enclosure pressure at a level that effectively prevents the ingress of flammable gases, vapors, dust, or fibers, thereby averting any potential ignition source. Additionally, a continuous flow of air or inert gas is upheld to disperse and eliminate any potentially explosive atmosphere. This protective approach is commonly applied to equipment that generates sparks, electric arcs, or hot surfaces during standard operation, as well as intricate industrial machinery and controls intended for operation within potentially explosive environments. This encompasses large machines, slip ring or collector motors, switch cabinets, control cabinets, and analytical apparatus.
