"Work in Hypoxic Conditions" (PDF).
"However, at 15 oxygen level, risk for fire still exists, and the system cannot be seen as an alternative to extinguishing systems.".Nist SP 984-2; nist Special Publication 984-2; Nilsson, Martin (2013).The methodology of the Isolcell N2 FireFighter is based on that principle: to keep the atmosphere in the areas to be protected low in oxygen, less than normal ambient.In a normobaric hypoxic ministere de la defense concours civils environment, common materials cannot ignite or burn. So, how about airline crew?1, thus, considering the fire triangle, a fire cannot occur because of the lack of sufficient oxygen. OK, so there is no point arguing the toss, osha (the US Occupational Safety and Health Administration) says that people cant work in oxygen levels lower than.5 percent and thats the end of the conversation.
Hypoxic air generators can be located inside or outside the protected rooms.4, smoke detectors are installed in protected volumes because, similar to gas suppression systems, hypoxic air does not prevent complication suite a une reduction mammaire smoldering and pyrolyzing processes.You can use oxygen reduction to prevent fires in for unoccupied spaces or areas that are infrequently visited such as museum archives but you would have to equip the personnel with oxygen masks etc.So, basically, colocation data centres (where traffic is highest) cannot be fitted with oxy-reduct in the USA unless you provide breathing sets, which is just not going to happen, right?"Advantages and challenges with using hypoxic air venting as fire protection".
