oxygen is lifesaving gas but it is harmful to
Answers
Answer:
Oxygen is crucial to maintain and save human life. Other than medical purposes it is widely used for manufacture of mineral water, fabrication works and other industrial activities. If adequate precautionary measures are not adopted while handling, storage or transport of oxygen cylinder or container, accidental blast may claim human life and other damage as well. The case involving three victims is presented to highlight various relevant aspects i.e. autopsy findings, cause/s of blast and recommended precautions are discussed in the light of oxygen cylinder blast case in an” oxygen filling factory”, claiming three human lives.
The air we breathe contains about 21% oxygen. Without oxygen we would die in a matter of minutes1. Many people at work and sometimes at home use oxygen gas in cylinders. It is widely used in welding, people who work in deep sea diving, for food preservation, in steel works and for medical purpose etc. Greensmith2 has observed that hyperbaric oxygen therapy potentially can provide enhanced oxygen delivery to peripheral tissues affected by vascular disruption, cytogenic and vasogenic edema and cellular hypoxia caused by extremity trauma. After appropriate resuscitation, macrovascular repair, and fracture stabilization, adjunctive hyperbaric oxygen therapy can enhance tissue oxygen content.
In growing edge of industrial and medical advancements, increased use of compressed gases like oxygen, nitrogen, carbon dioxide, helium, argon, krypton, acetylene etc is the need of an hour. Inspite of being vital to the human life, oxygen can be most dangerous to snatch a soul from body if not handled with caution. Few lay press news items such as three people were killed and one injured after an oxygen cylinder blast at their job site3, and two people died and one sustained serious burns after cylinder blast4 while filling gas are not uncommon.
Gases in their compressed state, and particularly compressed air, are almost indispensable to modern industry can cause disastrous effect in absence of proper handling, storage and transport. Precautions taken during handling, storage and transport can save damages to both human beings and inanimate things. Rani m et al have reported a case of a 34-year-old male welder who died following injuries sustained from explosion of an acetylene gas-welding cylinder.
Answer:
Oxygen toxicity, caused by excessive or inappropriate supplemental oxygen, can cause severe damage to the lungs and other organ systems. High concentrations of oxygen, over a long period of time, can increase free radical formation, leading to damaged membranes, proteins, and cell structures in the lungs.
