Inert gas asphyxiation Inert gas asphyxiation Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, rather than atmospheric air (which is largely composed of nitrogen and oxygen). Examples of physiologically inert gases, which have caused accidental or deliberate death by this mechanism, are argon, helium, nitrogen and methane. The term "physiologically inert" is used to indicate a gas which has no toxic or anesthetic properties and does not act upon the heart or hemoglobin. Instead, the gas acts as a simple diluent to reduce oxygen
Phase-out of incandescent light bulbs their color temperature may not lower, as it does with incandescents. Phase-out of incandescent light bulbs Governments around the world have passed measures to phase out incandescent light bulbs for general lighting in favor of more energy-efficient lighting alternatives. Phase-out regulations effectively ban the manufacture, importation or sale of incandescent light bulbs for general lighting. The regulations would allow sale of future versions of incandescent bulbs if they are sufficiently energy efficient. Brazil and Venezuela started the phase-out in 2005, and the European Union, Switzerland, and Australia started to phase them out in 2009. Likewise, other nations are implementing new
