Hazards caused by insufficient oxygen in industrial production

In general, in industrial production, if you work in a confined space, it is very easy to encounter insufficient oxygen. So in production, what kind of characteristics will there be when encountering this situation? This is a question we want to introduce to you.
Oxygen deficiency in confined spaces of industrial production is a frequently encountered situation. Oxygen insufficiency can be caused by many factors, such as crowding by dense gases (such as carbon dioxide), combustion, oxidation (such as rust), microbial behavior (such as mouse decomposition), absorption and adsorption (such as wet activated carbon), work behavior (such as using Solvents, paints, cleaning agents or heat work) etc. can affect the oxygen content.
Another point that should be taken very seriously is that after workers enter, they may suffocate due to lack of oxygen, and oxygen exceeding the constant may accelerate combustion or other chemical reactions.
