Do indoor storage tanks require fire dikes and cofferdams?
Thread Content
Hydrogen peroxide, concentrated sulfuric acid, and liquid caustic soda – the first two are classified as Category A substances; is it necessary to construct a fire dike? Is it required to set up a bund for liquid caustic soda?
To install dikes and protective barriers, it is best not to store items in the workshop
It depends on the size of your storage tank! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
20 m3 of hydrogen peroxide, concentrated acid and liquid alkali – 10 m3 each; factory dimensions: 13.5x30x6
Personally, I think such a small reserve doesn’t require the installation of fire dikes or cofferdams! ! ! ! ! ! ! ! ! ! ! ! ! ! !
Small storage tanks aren’t necessary, right! Otherwise, wouldn’t the workshop still be full of walls and barriers?~
The feeling of the intermediate tank.........
Principles for setting up cofferdams: Cofferdams should be installed in areas that may be contaminated by flammable liquids, corrosive substances, or toxic materials during operations or maintenance； Corrosion-resistant flooring should also be installed in the areas of equipment that handle corrosive media. You mentioned earlier that the operating media are hydrogen peroxide, concentrated acids, and concentrated alkalis, which are corrosive substances; therefore, these facilities should be enclosed with a dike, preferably a large one.
Yes, similar to an intermediate tank – it can be filled at any time and used immediately. Is that how it’s set up?
The people in charge of environmental and safety assessments say this is quite convincing. Storage tanks with flat bottoms are usually equipped with dikes; if the volume isn’t very large, you can use vertical tanks with double ends. I think storage tanks will always accumulate dirt
