Abstract
With the continued outbreak of the coronavirus and the increase in the need for medical oxygen, it became necessary to take all measures for the safe handling of gas. Oxygen is very reactive and behaves differently to air, compressed air, nitrogen and other inert gases. Medical oxygen, at high pressure, from a cylinder, can react violently with hydrocarbons such as oil and grease which may be used mistakenly in cylinder valve or regulator. The oxidation products are a potentially explosive hydroperoxide. Nearly all materials including rubber, textiles, and metals will burn vigorously in the presence of oxygen. Atmospheric air contains nitrogen 78%, oxygen about 21% and with 1% remaining including a variety of other gases like carbon dioxide and argon. Even a small increase in the oxygen level in the air to about 24% can create a dangerous situation. It becomes easier to start a fire, which will then burn hotter and more fiercely than in atmospheric air and may be impossible to put the fire out. Increase the concentration of oxygen due to leaking valve or hose in a poorly ventilated room or in confined space can quickly create a dangerous level.
Highlights
A fire requires three elements before it can burn
Increase the oxygen concentration due to leaking valve or hose in a poorly ventilated room or confined space can create a dangerous situation from fire and explosion standpoint
The matter that makes it imperative for everyone to use the safe gas by increasing awareness and education about gas dangers and how to handle the safe way to prevent fire and explosion accidents of gas cylinders
Summary
A fire requires three elements before it can burn. The first is heat; even though fire produces heat, it needs a source of heat as an ignition source to start burning. The most important chemical reaction of a hydrocarbon, for lubrication is oxidation. Paper, fuel oil or natural gas, for example, the hydrocarbons are oxidized. Hydrocarbons as oils consider as fuels that readily combust at high and enough temperatures and that combustion can begin in the absence of a spark under certain conditions [1]. High concentration of oxygen can make objects burn and in some extreme cases explosion can occur [2]. Resins, monomers, peroxides and explosives all have the potential to produce heat by exothermic reactions, these are typically unwanted. Oil and grease are extremely dangerous when contrasts to oxygen because they can be ignited and burn explosively due to a chain reaction occurs in oxygen equipment. It is very important that oil and grease must never be used to lubricate a valve spindle if it comes into contact with oxygen
