Considerations regarding the inspection of equipment designed for use in potentially explosive atmospheres

The special characteristics providing protection to explosion for equipment design for use in potentially explosive atmospheres must be preserved during their entire period of use. Thus, the equipment designed for use in potentially explosive atmosphere shall be subjected to specific inspections in order to verify that the characteristics on which explosion protection is based were not depreciated in time. The purpose of the paper is to underline the importance of inspections in case of equipment intended to be used in potentially explosive atmospheres and to provide specific recommendations in this matter.
