A product that is free of controversy

The man-portable oxygen cylinders are filled with liquefy oxygen. Mostly use for medical checkup purposes or in areas with scarce or no oxygen uniform under water or at high levels above the underseal i.e. aerospace.Medically, oxygen hit man is used in the treatment of gas poisoning, pneumonia, used as an anesthetic when mixed with nitrous oxide or administered in inadequacy of oxygen (Rees, Dudley, 2006).Liquefied oxygen is pale blue in color, and has a compactness of 1.141g/cm3. The liquefiable has a boiling operate of -182.96oC and a freezing point of -222.65oC. Its raw material is oxygen which is obtained from natural air by a process know as fractional distillation. At 20oC the liquid gas has an expansion rate of 8601 (OLeary, 2000).Fractional distillation is done in a factory with boilers this touchs the laborers to work at very cold environments which are exceedingly in flammable. Natural air is made up of different gases which has different dehydration or freezin g points. The natural air is first liquefied to be liquid air which has a mixture of liquid nitrogen and liquid oxygen with boiling points of (-196oC) and (-183oC) respectively.Liquid air is heated to -183oC which oxygen evaporate, its tapped and liquefied again now as oxygen liquid which is then jammed in high pressure cylinders for distri scarceion. Most of the cylinders meet minimum requirements of deliberateness 5 pounds and under and usually last up to 5 hours or more (Portableoxygen, 2009). The cylinders administer oxygen in pulses through a turn know as a conserver which delivers a pulse of oxygen when the substance abuser inhales.Ethical considerations of the product are the liquefied gas is highly explosive and flammable hence it use for industrial purposes. Due to its properties of being highly flammable and explosive some people mix it with powdered charcoal to make explosives which are lethal.The product should be produced the way its being done but its distributions should be controlled and sold only to authorized dealers and users to minimize its use to jell explosives.ReferencesOLeary, D.
