May I ask whether it is in compliance with the regulations to pump Class A and B flammable liquids, stored in 200 kg barrels, into the storage tanks in the workshop?
Thread Content
Is it in compliance with the regulations to use 200 kg drums of Class A and B flammable liquids, and pump them through a fixed pipeline to the storage tanks in the workshop? Aren’t there specific regulations for the unloading of Class A flammable liquids? What should be done?
It should be possible, but an anti-static device is necessary. Our ethylenediamine is supplied in 200-liter drums, and it is transferred via pipelines to the dosing tank in the workshop.
The key is how to ground the barrel? ? ? What method should be used?
The tank is simply positioned on the ground without being grounded, so the liquid inside the tank can be considered almost stationary, while the pipes are grounded.
Does that pipe need to be connected from the top? What kind of pump should be used for pumping? Is a loading/unloading arm needed?
Is the suction tube of that pump a hose? Is it inserted from the top of the tank?
Just one word proves you can’t; drawing is of course not an option, while fighting is somewhat acceptable； Direct repackaging operations (filling) cannot be carried out inside the warehouse; ensure proper grounding, use volume pumps whenever possible, and implement nitrogen protection as well as fire prevention measures~~~
May I ask how to fill the barrels? Doesn’t one need to insert a tube at the top and then use a pump to draw it out in order to fill them? I also would like to ask how to ground this tank and pump? How should nitrogen protection be carried out? Could you please explain it in more detail? Thank you!
I recommend a standard that provides detailed descriptions of the methods for static electricity grounding in the petroleum and fine chemical industries; additional pages in this standard include illustrations showing how such grounding should be implemented. It is the SHT 3097-2017 Standard for Static Electricity Grounding Design in Petroleum and Chemical Industries
