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.
