Overview
This document (EN 16750:2017) has been prepared by Technical Committee CEN/TC 191 "Fixed firefighting systems", the secretariat of which is held by BSI (United Kingdom) The responsible German standardization committee is Working Committee NA 031-03-04 AA "Feuerlöschanlagen mit gasförmigen Löschmitteln und deren Bauteile - SpA zu CEN/TC 191/WG 6" ("Gas extinguishing systems and their components - mirror committee of CEN/TC 191/WG 6") at DIN Standards Committee Firefighting and Fire Protection (FNFW). This European standard specifies oxygen reduction systems that are used as fire prevention systems by creating an atmosphere in an area which is having a lower permanent oxygen concentration as in ambient conditions. The level of oxygen reduction is defined by the individual risks of these areas. Oxygen reduction is achieved by technical systems which are providing a flux of air containing a reduced concentration of oxygen. The standard specifies minimum requirements and defines the specifications governing the design, installation and maintenance of fixed oxygen reduction systems with oxygen reduced air in buildings and industrial production plants. The standard also applies to the extension and modification of existing systems. This European standard applies to oxygen reduction systems using nitrogen which are designed for continual oxygen reduction in enclosed spaces. This European standard does not apply to oxygen reduction systems that use water mist or combustion gases. The European standard does not apply to: - explosion suppression systems; - explosion prevention systems; - fire extinguishing systems using gaseous extinguishing agents; - inertization of portable containers; - systems in which oxygen levels are reduced for reasons other than fire prevention (for example, steel processing in the presence of inert gas to avoid the formation of oxide film); - inerting required during repair work on systems or equipment (such as welding) in order to eliminate the risk of fire or explosion. In addition to the conditions for the actual oxygen reduction system and its individual components this European standard also covers certain structural specifications for the protected area. The space protected by an oxygen reduction system is a controlled and continuously monitored indoor climate for extended occupation. This standard does not cover unventilated confined spaces that may contain hazardous gases.
