Although oxygen is a taste, color, and odorless gas, it varies depending on the type of work it does. We know that the level of oxygen in the atmosphere is only 20%, and the rest is other gases.
Industrial grade oxygen is the oxygen that is used and refilled for work in the industry.
If we look at the industrial level oxygen quality (99.2%), we can see that there is very little difference between the oxygen level and the medical oxygen level (99.5% +). Even the source of refilling such oxygen cylinders is no different.
This raises the general question: What is the main difference between these two types of oxygen? In that case, the answer is different in terms of usage and quality assurance.
Let me explain the matter in a little more detail. The use of industrial grade oxygen is versatile including steel cutting, combustion, oxidation, welding etc. The oxygen used here does not explode on its own but acts as an explosion catalyst. In this way the mentioned works of the factory can be done easily without any hassle.
And when it comes to quality assurance, the standards that the United States Pharmacopoeia (USP) has set for America are followed worldwide. The Directorate General of Drugs Administration (DGDA) along with other authority ensures that this is being used appropriately in the context of Bangladesh.
Proper labeling of the cylinder and checking for the presence of combustible gases like acetylene in it is to be ascertained. Oxygen and hydrogen reactions during factory work may have caused such gases to form inside the cylinder. If gas is present, the cylinder must be vacuumed, otherwise an explosion may occur while refilling.
The last thing is more important to ensure that the cylinder in which the factory grade oxygen will be filled will not be usable for any work other than factory work. Only then a safe working environment of the factory will be maintained and any unwilling accident can be avoided.
