Oxygen (O₂)
The oxidizing gas used for life sustaining and performance optimization applications
Oxygen is a colorless, odorless reactive gas and the life-supporting component of air. It forms just under 21% of the earth's atmosphere, and is the most abundant element in the earth's crust, mainly in the form of oxides, silicates, and carbonates.
In addition to its use as a respiratory gas for healthcare applications, oxygen has strong oxidizing properties that can benefit many industries by improving yields, optimizing performance, lowering costs and reducing carbon footprint compared to other fuels. Oxygen enrichment or replacement of air also enhances chemical and biological process efficiency.
Applications using oxygen include combustion, oxidation, fermentation, wastewater treatment and aquaculture. Combined with acetylene (C₂H₂) or other fuel gases or with argon (Ar) and carbon dioxide (CO₂), oxygen is also used for metal cutting, welding, scarfing, hardening, cleaning, and melting applications. In the food industry, oxygen is used to maintain a fresh, natural color, for example for fresh meat.

Integra® Oxygen Cylinder and Flashback Arrestor
Safer:
- Built in flashback arrestor
- Reduced exposure to pressure hazard, built-in regulator controls pressure and cannot be removed
- Reduced risk of regulator damage, regulator fully contained within protective guard
- Shorter and more stable cylinder has reduced risk of falling
Easier to use:
- Smaller, lighter and more manoeuvrable than traditional cylinder
- Snap-on connectors (no need for spanners)
- Hand-operated on/off valve (no need for bottle keys)
- Pre-set flow eliminates set-up time
More efficient
- Never buy, repair or calibrate a regulator again
Transporting Cylinders? Drive Safely and Arrive Safely
There are some basic safety rules to follow when transporting cylinders :
- No smoking
- Check that cylinder valves are properly closed and that valve caps are fitted
- Ventilate your vehicle
- Disconnect regulators, hoses and torches, etc.
- Secure cylinders properly to prevent them from moving
- Go directly to your destination
- Do not leave cylinders inside the boot or in an unventilated place
- Immediately unload at destination or if stopping for a longer time and store in a ventilated place
For further information, please take a look at the 'Safe Transport of Gas' guide provided by European Industrial Gas Association (EIGA).
