A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...

Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Oxygen tanks containing pressures of up to 200 bar (3000 psi) are used for industrial processes including the manufacturing of steel and monel, welding and cutting, medical breathing gas, diving and as an emergency breathing gas in aircraft. A small steel tank of 16 litres water capacity with a working pressure of 139 bar (2015 psi), holds ...
In which pO 2 is the chosen maximum partial pressure of oxygen in atmospheres absolute and the FO 2 is the fraction of oxygen in the mixture. For example, if a gas contains 36% oxygen (FO 2 = 0.36) and the limiting maximum pO 2 is chosen at 1.4 atmospheres absolute, the MOD in feet of seawater (fsw) [Notes 1] is 33 fsw/atm x [(1.4 ata / 0.36 ...
A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or (b) is completely gaseous at 20 °C (68 °F) at a standard pressure of 101.3 kPa (14.69 PSI). Gases are assigned to one of three divisions division 2.1 Flammable gas; division 2.2 Non flammable, Non-toxic gas; division 2.3 Toxic gas
