Process Area Event – [I See Now-16]: Excess Oxygen in Confined Spaces Is Also a Hazard

Container construction was carried out; I can’t remember whether it was about grinding welds or something similar, but in any case, grinding and other such tasks were done in a confined space. The workers were grinding inside; it was hot, and the air wasn’t circulating well, so they soon started sweating profusely. The workers inside shouted to those outside, it’s too hot; let in some air. Then that fool outside brought over the oxygen tube to blow into it. It is easy to imagine that with a high oxygen concentration, the sparks generated during grinding can instantly set a person on fire; it’s a truly tragic scene. The space is small; people outside can’t get in, and they have to watch helplessly as this burning person screams in pain.
Using an oxygen tube to blow – is that stupid or idiotic? How is training carried out...
Can I ask a stupid question: Isn’t oxygen used to support combustion? How could a fire start? How can it spread?
Moreover, introducing pure oxygen into a confined space can cause oxygen poisoning
It’s probably hired from the market; I don’t know if they’ve received any training.
Sparks are generated during grinding. In an oxygen-rich environment, all organic materials, including the human body, become flammable and explosive; therefore, open flames must be avoided at all costs. The final conclusion remains that oxygen facilitates combustion, rather than causing it.
So high oxygen levels aren’t necessarily a good thing either.
A few years ago, a subcontractor came to our company to carry out waterproofing work on the top floor of an office building. The on-site orientation and safety training took about 2 hours, and the subcontractor’s boss was unhappy – he thought it was taking too long, considering how many waterproofing projects he had completed before. . . As a result, in the same year, a worker who was working on waterproofing tasks fell from the roof, from the 7th floor.
That person truly intended to kill him! ! ! We have to catch them! ! !
Even when patients receive oxygen therapy, it is not high-purity oxygen used; although oxygen is beneficial, consuming too much of it is not good~
