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
Longest-lasting light bulbs Longest-lasting light bulbs This is a list of the longest-lasting incandescent light bulbs. The world's longest-lasting light bulb is the Centennial Light located at 4550 East Avenue, Livermore, California. It is maintained by the Livermore-Pleasanton Fire Department. The fire department claims that the bulb is at least 117 years old (installed 1901) and has only been turned off a handful of times. The bulb has been noted by The Guinness Book of World Records, Ripley's Believe It or Not!, and General Electric as being the world's longest-lasting light bulb. While it might seem astonishing that so many longest-lasting light bulbs
