Oxygen (O2) is a gas that is vitally important to each organism. It is odourless, colourless and tasteless gas. Liquid oxygen is characterised by light-blue colour.
All elements, except for inert gas, react with oxygen under various temperatures by forming oxides.
Oxygen is used in many areas, i.e. it serves as a vitally important gas not only in medicine, but is also irreplaceable in industry – production of steel, metals, smelting of non-ferrous metals, cutting and processing metal with gas, production of glass and many fields of chemical industry.
Oxygen is obtained from atmospheric air, by liquefying and rectifying it at low temperatures. Oxygen is filled in blue coloured cylinders with white shoulder and cryogenic tanks.

Industrial areas:
Oxygen is widely used in various metalworking processes due to its ability to sustain intense combustion and generate high temperatures:
Gas welding (oxy-fuel welding) – mixed with acetylene or other fuel gases to create a high-temperature flame for joining metals.
Flame surface treatment – for edge bevelling, rust, paint, or contaminant removal before welding.
Gas cutting (oxy-fuel cutting) – pure oxygen is directed onto heated metal, causing rapid oxidation and producing precise cut lines.
Plasma cutting and welding – used as an auxiliary gas to improve cut quality and speed.
Flame hardening and heat treatment – for surface hardening, tempering, or other thermal processing procedures.
High-power industrial processes – used to stabilize flames, increase combustion efficiency, and optimize heat transfer.
Safety:
The increase of oxygen concentration by just a few percentage points causes a risk of fire. The sparks that are usually considered as non-hazardous may cause
