| Feb 22, 2015 at 20:12 | comment | added | permeakra | AFAIK, alkalies dissolve most materials at elevated temperatures. I guess, that in your case the only acceptable materials are steel and silver, most other metals and ceramics will dissolve in molten alkalies. | |
| Feb 22, 2015 at 20:06 | comment | added | permeakra | carefully read everything about 'purity' and carbonate content. While not a problem in lab setting, when it is trivial to add some more $\ce{KOH}$, tossing around such big quantities may cost. Personally, I highly recommend to have a shower nearby and a fresh set of clothes for an emergency, alkaline burns must be dealt with as fast as possible (they are worse then acidic burns). | |

changed wording to avoid confusion

| Feb 22, 2015 at 19:36 | comment | added | cryptex | Just to add to the above comment. There are 3 of us, one has a masters in chemistry and other a degree in marketing. I happen to be an engineer. And no, I am not going to build anything of such magnitude in my basement :P We have worked at levels of few hundred ml and for the next few months it would be under 10 lt; 500 is a yr or 2 away. Till now we have only performed at a laboratory scale. That too under the guidance of a faculty. Our guide has put us in touch with some people from the industry, while we are evaluating that I at a personal level am trying to gauge what we are getting into. | |
| Feb 22, 2015 at 5:55 | comment | added | cryptex | Ok just to clear the air. I am planning to leave my job to open a manufacturing company of my own. And yes i will be hiring professionals to help me out, but i dont think it would hurt to know a few things before so that when they start talking at least i understand a bit of they are saying. to reiterate I am not crazy enough to handle such large amounts on internet advice. No its not one large 1000 liter container. Actually I will be needing only 500 liters and i plan on dividing it in 5 containers. The facility will be in a industrial area with nothing around within a 700m radius. | |

| Feb 21, 2015 at 21:31 | comment | added | Jori | Besides that, I think it is very likely, as Mad Scientist already noticed, that such storage is illegal without the proper licenses and "proof of knowledge". | |
| Feb 21, 2015 at 21:30 | comment | added | Jori | @KlausWarzecha Sure I have asked a lot of safety questions when I first came here and I'm really glad you guys helped me out (and still do!). But there is a difference between asking which type of gloves would be preferable for handling small quantities of sulfuric acid in a home lab for instance, or asking about storing an industrial scale amount of quite hazardous chemicals. Wrongly handling 1000 liters of $\ce{KOH}$, especially at elevated temperature, could very likely get you killed and perhaps also others in the neighborhood of said storage. | |
| Feb 21, 2015 at 21:22 | comment | added | Jori | @MadScientist I should have been more careful with my wording. I agree with you. I was of course talking about the craziness of someone asking about storage of such industrial scale quantities and needing internet for safety advice. Answering this question and leaving it open would IMHO indicate that we think it is OK to ask such things here and rely on our answers. Especially since OP is not asking about theoretical procedures of storage but about actually handling 1000 LITERS of dangerously corrosive $\ce{KOH}$. | |
| Feb 21, 2015 at 20:10 | comment | added | Klaus-Dieter Warzecha | @Jori Safety, covering advices on personal protection during the handling on particular compounds, suggestions for alternative and less toxic reagents and the advice to better not do something at all always had their place here - for good reason. Consequently, I voted to leave the question open. | |

| Feb 21, 2015 at 19:49 | comment | added | Mad Scientist | @Jori I disagree that safety should be off-topic. Though I can agree that this particular case is asking about a scale where I'm rather uncomfortable having it here. Anyone handling reactions on a thousand liter scale shouldn't ask the internet for help, they should have people that know this stuff already. Anyting else would be dangerous and very likely illegal. | |
| Feb 21, 2015 at 19:37 | comment | added | Jori | I'm voting to close this question as off-topic because it asks about safety advice. We are not here for that (and should not IMHO). Please consult a professional company for advice. | |
