Inert gas asphyxiation accidental death in humans, inert gas asphyxia with gases including helium, nitrogen, methane and argon has been used as a suicide method. Inert gas asphyxia has been advocated by proponents of euthanasia, using a gas-retaining plastic hood device colloquially referred to as a suicide bag. Nitrogen asphyxiation has been suggested by a number of lawmakers and other advocates as a more humane way to carry out capital punishment. In April 2015, the Oklahoma Governor Mary Fallin signed a bill authorizing nitrogen asphyxiation as an alternative execution method in cases where the state's preferred method of lethal injection was not available
Phase-out of incandescent light bulbs from broken bulbs may be overstated, and can be ameliorated by taking a few simple steps. No mercury is used in the manufacturing of LED lamps, a different technology replacement for incandescent lamps. In addition, LED lamps do not require warmup time in cold weather, and in fact, perform better in colder temperatures, making them an excellent choice for use in cold locations, such as refrigeration units. The initial cost of CFLs and LEDs are higher than that of incandescent light bulbs. Typically this extra cost is repaid in the long-term, as both use less energy and have longer operating
