Oxygen concentration in normal ambient air is approximately 20.9%. When the oxygen concentration in air drops to 19.5%, it is considered by OSHA to be oxygen deficient, and at 16% or below it is considered unsafe for humans and may be lethal. \u00a0Oxygen deficiency is particularly dangerous as humans are unable to sense it on their own, and many inert gases that displace oxygen are odorless, tasteless, and invisible.<\/p><p>Many common work environments have the potential for oxygen deficiency hazards. Any applications using compressed inert gas or cryogenic gases can pose an oxygen deficiency hazard in the event of a leak, necessitating oxygen monitoring. High oxygen concentrations can also pose a risk \u2013 if oxygen exceeds 24% concentration it may considerably increase the risk of fire.<\/p><p>\u56fa\u5b9a\u5f0f\u9178\u7d20\u30e2\u30cb\u30bf\u30fc\u306f\u3001\u30dd\u30fc\u30bf\u30d6\u30eb\u30e2\u30cb\u30bf\u30fc\u306b\u4ee3\u308f\u308b\u3001\u4fbf\u5229\u3067\u4f4e\u30b3\u30b9\u30c8\u3001\u304b\u3064\u4fe1\u983c\u6027\u306e\u9ad8\u3044\u9078\u629e\u80a2\u3092\u63d0\u4f9b\u3057\u307e\u3059\u3002\u5f53\u793e\u3067\u306f\u3001\u4ee5\u4e0b\u306e\u4e21\u30bf\u30a4\u30d7\u306e\u56fa\u5b9a\u5f0f\u5468\u56f2\u7a7a\u6c17\u30e2\u30cb\u30bf\u30fc\u3092\u88fd\u9020\u3057\u3066\u3044\u307e\u3059\u3002 <a href=\"https:\/\/sso2.com\/ja\/%e8%a3%bd%e5%93%81\/ambient-air-oxygen-analyzer\/\">\u9178\u7d20<\/a> and a\u00a0<a href=\"https:\/\/sso2.com\/ja\/%e8%a3%bd%e5%93%81\/ambient-air-oxygen-analyzer-carbon-dioxide-analyzer\/\">\u30c7\u30e5\u30a2\u30ebO2\uff06CO2<\/a> \u30a2\u30ca\u30e9\u30a4\u30b6\u30fc <a href=\"https:\/\/sso2.com\/ja\/%e7%92%b0%e5%a2%83%e5%a4%a7%e6%b0%97%e3%83%a2%e3%83%8b%e3%82%bf%e3%83%bc\/\">OMD-351<\/a> series utilizing our state-of-the-art precision electrochemical sensor technology.
