A room is intended to facilitate the entry of personnel<\/p>\n<p>.<\/p>\n<p>and<\/p>\n<p>The term &#034;room&#034; also<\/p>\n<p> includes inlet and outlet ducts. An acoustic hood and other like enclosures designed to permit the entry of personnel can be considered as a room.<\/p>\n<p>This document also includes requirements related safety devices and controls necessary to ensure that artificial ventilation, purging and pressurization is established and maintained.<\/p>\n<p>A room assembled or constructed on site, can be either on land or off-shore. The room is primarily intended for installation by an end-user but could be constructed and assessed at a manufacturer\u2019s facility, where the final construction such as ducting can be completed on site.<\/p>\n<p>Rooms can be located in an explosive gas atmosphere requiring EPL Gb or Gc, or a combustible dust atmosphere requiring EPL Db, or Dc.<\/p>\n<p>This document does not specify the methods that may be required to ensure adequate air quality for personnel with regard to toxicity and temperature within the room. National or other regulations and requirements may exist to ensure the safety of personnel in this regard.<\/p>\n<p>Protection of rooms by using an inert gas or a flammable gas is outside of the scope of this document. It is recognized that such applications are special cases, which in part may be addressed using the principles from <\/p>\n<p>IEC<\/p>\n<p>UL<\/p>\n<p> 60079-2, but in all probability will also be the subject of additional, stringent engineering standards, procedures and practices. Pressurized enclosures for equipment that are not intended to facilitate the entry of personnel are addressed in <\/p>\n<p>IEC<\/p>\n<p>UL<\/p>\n<p> 60079-2, and are not in the scope of this document.<\/p>\n<\/p>\n<p id=\"NOTEMaintenanceRecommendationsAreCo-F208767E\">\n<p>1.3 DR NOTE Maintenance recommendations are contained in Annex A<\/p>\n<p> until they can be included in IEC 60079-17<\/p>\n<p>.<\/p>\n<\/p>\n<p>This document supplements and modifies the general requirements of <\/p>\n<p>IEC<\/p>\n<p>UL<\/p>\n<p> 60079-0, except exclusions as indicated in .
