Use of a suicide bag in a well ventilated room using either of these gases is unlikely to pose a hazard for other people, and there is no fire hazard. [ 30 ] Propane, butane and natural gas are to varying degrees narcotic, and are a serious fire and explosion hazard, depending on concentration of the gas and of oxygen. [ 32 ]
Contact cement, a fast-drying glue, is widely used as an inhalant, as it typically contains solvents such as toluene which vaporize at room temperature. Even though solvent glue is normally a legal product, there is a 1983 case where a court ruled that supplying glue to children is illegal.
Release of helium boiled off by the energy released in a magnet quench such as the Large Hadron Collider or a magnetic resonance imaging machine. Climbing inside an inflatable balloon filled with helium [7] Direct administration of gas Inadvertent administration of asphyxiant gas in respirators [8] Use in suicide [9] [10] and erotic ...
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
1840 illustration of a man inhaling nitrous oxide, and another experiencing its effects Until at least 1863, low availability of equipment to produce the gas, combined with low usage of the gas for medical purposes, meant it was a relatively rare phenomenon that mainly happened among students at medical universities.
A major advantage is that this gas is noncombustible. But the use of helium has some disadvantages, too: The diffusion issue shared with hydrogen (though, as helium's molecular radius (138 pm) is smaller, it diffuses through more materials than hydrogen [4]). Helium is expensive. Although abundant in the universe, helium is very scarce on Earth.

When an electron is forced into liquid helium rather than floating on its surface, it forms a bubble rather than entering the liquid. The size of this bubble is determined by three main factors (ignoring small corrections): the confinement term, the surface tension term, and the pressure-volume term.
