...experimenters of the Department of the Interior, according to their claim, have found that, by mixing helium instead of nitrogen with oxygen, a breathing mixture is formed equally as good as ordinary air, and the helium has not the tendency to "bubble" and cause the disease when the pressure is released...
Ordinary air is composed of four-fifths nitrogen and one-fifth oxygen and smaller amounts of other gases such as carbon dioxide. The oxygen content of air is the only part valuable to man in breathing. When men work in certain types of caissons, in diving suits or diving bells, they are subject to great air pressure. Under these circumstances, nitrogen goes into the tissues of the body. When the external pressure is released, as by coming out of a caisson or being raised to the surface of the water, the excess nitrogen in human tissues tends to form bubbles...
Experiments with animals, partially confirmed by experiments with men, showed that the time of gradual decompression with helium-oxygen mixtures can be reduced even to one-sixth of that required with ordinary air without evil effects. If so, the use of helium-air will greatly increase the margin of safety for workers in compressed atmospheres...
...Firedamp is a gas given oft by coal when freshly exposed to the atmosphere, which, when mixed with from four to twelve times its volume of air, is explosive. A common name for it is marsh gas; in substance, it is carbureted hydrogen, oxygen...
...Shipping Board. He fitted her out for diving and salvaging, and laid in an equipment of patent diving suits of manganese bronze (which resists salt water corrosion), with flexible parts of interlocking copper tubing and ball bearing joints, with portable air equipment, carrying a four-hour supply of oxygen and a telephone...
