Look at the Yima accident to understand what a sand explosion is
Thread Content
The cause of the Yima accident has been identified
After air separation equipment has been in operation for a long time, leaks may occur in the pipes and other components inside the cryogenic tank, requiring maintenance work. It is necessary to remove the perlite sand from within the cryogenic tank, and at this time sand explosions can easily occur, leading to casualties.
Causes of sand explosion accidents: (1) Insufficient amount of nitrogen gas in the cold box, which can lead to localized concentration of oxygen; (2) Inadequate heating in certain areas of the cold box containing perlite sand, resulting in the accumulation of oxygen-rich liquid; (3) Leaks from equipment within the cold box; (4) Perlite sand becoming damp and clumping together; (5) Residual liquid in the distillation tower
A typical decision-making issue that arises when safety hazards conflict with production tasks. It reminds me of the issue of “refusing to follow illegal orders” and defying authority; it’s truly difficult to do so, but is that any better than risking one’s life? ? ? What can this accident teach those who may encounter similar incidents in the future? Is there really no way to convince your supervisor? If they had known about such consequences in advance, how would those who left have behaved differently if they had another chance to live? ? ?
Hehe, “Only those who are alive have the right to speak” – that’s true. But who can actually hold this power in their own hands and use it once to save themselves:shutup:
A small mistake, and so many precious lives are lost. Are many operators a bit nervous these days?
