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 have had exchange programs to replace incandescent bulbs with energy efficient versions. Ghana banned incandescent bulbs in 2008 and Senegal has banned the manufacture and import. Egypt is reported to have a partial ban on incandescent light bulbs. Kenya has a programme to exchange a number of light bulbs with more efficient types. Morocco has a programme to exchange a number of light bulbs with more efficient types. Namibia has an exchange program which distributed 1 million energy saving bulbs in 2016. Rwanda has an exchange program, distributing CFL bulbs. South Africa phased out incandescent light bulbs in 2016. Tanzania
