Regarding the fact that many factories these days are designed with an instrument compressed air system connected to a nitrogen system, so that nitrogen is automatically supplied when there is a shortage of compressed air, what safety measures do you take? Are there any cases of accidents to share? If done poorly, it can be fatal.
All the gas sources in our school’s steel plant are nitrogen; once, during maintenance work, I inhaled some of it by accident and almost fainted. Therefore, it is necessary to take proper safety measures and never be careless
Haven’t encountered it yet; came to learn about it*
There are no such cases, but one thing to keep in mind is that there is some leakage in the instrument pipelines; it is not advisable to carry out such modifications indoors； There is a risk of suffocation.
Those who say there are no cases just don’t know. There have been both near-miss accidents and deaths from asphyxiation, so I’d like to warn everyone
Today’s devices are all of a frame-type design, with good ventilation; safety precautions must definitely be taken when working in enclosed spaces, as one’s life is one’s own. It’s not as terrifying as the poster said
It is best not to mix nitrogen into compressed air to avoid asphyxiation accidents.
Furthermore, if insertion is necessary, someone should be there to supervise and manually carry out the insertion.
The post is here; it hasn’t been deleted. Nitrogen poses a risk, but it is generally said that the hazard is greater in enclosed spaces. After all, nitrogen makes up over 70% of the air.
It’s been deleted; it was a post from before, and there was a longer post written afterward that remained pinned, but suddenly it can’t be found anymore.
