Electric Powered Industrial Equipment, used in areas containing explosive or flammable materials, must be designed to prevent any operation of the equipment from igniting the atmosphere. The design and construction of EX Equipment permit their classification as Explosion Proof (EX) and enable their use in explosive and hazardous atmospheres.. Capella. – 27. th. March 2014.
