Inert gas asphyxiation lacks oxygen and consists of an asphyxiant gas (one or more of argon, nitrogen or carbon dioxide), causing the animals to lose consciousness. Argon and nitrogen are important components of a gassing process which seem to cause no pain, and for this reason many consider some types of controlled atmosphere killing more humane than other methods of killing. However, "stunning" is often done using carbon dioxide. If carbon dioxide is used, controlled atmosphere killing is not the same as inert gas asphyxia, because carbon dioxide at high concentrations (above 5%) is not biologically inert, but rather is toxic and also
Phase-out of incandescent light bulbs The directive EC 1194/2012 relates to mains voltage directional halogen lamps and means many common halogen reflector lamps such as D rated GU10's are affected. Iceland is following the same route as the EU. Montenegro banned incandescent bulbs over 100W from 1 July 2018, part of a phased ban. Norway has implemented the EU directive for the phase-out of incandescent light bulbs and has followed the same phase out route as the EU. There was a half-year delay in implementing the directive compared to the EU, but the phase out occurred at the same time since the affected light bulbs
