Ex11 Mechanical

Ex11 meets the competency requirements for EN 13463 Parts 1, 5 & 6 for operatives working with mechanical equipment.

Since the introduction of ATEX (DSEAR) users must identify all possible ignition sources that could arise in hazardous areas. The identification of these ignition sources includes electrical and non-electrical (mechanical) items of equipment. In addition to the existing safety measures applied to ensure safety of electrical equipment in hazardous areas measures for explosion safety now apply to non-electrical equipment. The safety measures for non-electrical equipment used in hazardous areas not only include the design of equipment but also those aspects required for safe selection, installation, maintenance, inspection and repair.
