Machinery must be designed and constructed in such a way as to avoid any risk of explosion posed by the machinery itself or by gases, liquids, dust, vapours or other substances produced or used by the machinery.
So it means: any potential hazardous area created within machinery shall be the responsibility of the manufacturer. In this case ATEX Directive is not to comply with. All assets installed to handle potential danger shall be with Ex compliance.
Machinery must comply, as far as the risk of explosion due to its use in a potentially explosive atmosphere is concerned, with the provisions of the specific Community Directives.
So it means: if machinery comes into potential hazardous environment, it must comply with ATEX.
Keep up the good work!
