As you read the forum you might find conflicting information, but everything you need to make your own decision is here, on the forum as well. For example, there are people who use Urea to neutralize Nitric Acid, this works so long as you are not creating Urea Nitrate. However, if you are following the steps most suggest, carefully, this means you are adding only small amounts of Nitric Acid, thus at the end of the reaction you have only added as much as needed and do not have excess Nitric Acid to burn off.
If you read something that is conflicting and do not understand the direction you should move, it might be prudent to then ask questions. However, if you learn enough, read enough, spend enough time bringing yourself up to speed, you will be able to read the material and make your own mind up what is safe or not. It's always good to ask at that point just to clarify the information and confirm your decision.
I try to do this, I think most of the members on this forum do much the same. And if you conduct yourself in a similar manor, help yourself before you ask politely for help, people here are not only going to help you, but also will appreciate your contributions even if only in the form of asking questions that are meaningful.
I feel the same as Butcher, you didn't try to hide what you have done, you apologized and I get a strong feeling you will conduct yourself in a more professional manor while on this forum.
There is something else I would like to mention just because I see it coming up a lot. You said you are running a business and driving a truck 12 hours a day just to make ends meet, or at least that's what it sounds like. I commend you by the way on your willingness to work and not fold or roll over. The problem I see however is that many people who are in situations where they need money turn to this as a way of getting them out of the hole. This very well could be that vehicle, however, unlike with other things you might be able to do, this takes time to learn, time to actually learn how to make it a profitable business. I am still working on the profitable part, everything I have made up to this point has paid the bills and whatever is left over has gone to purchasing equipment. It hasn't made a profit above and beyond my expenses yet. Not that I have done things strictly in the way if I wanted to make that happen, but even still I have started enough businesses myself to know that this isn't something you can jump right into and make a living at, You have to nurse it along, develop not only your business but your knowledge. If you are counting on this to get you out of a hole, it's going to be awhile before you can actually do that. Knowing this I hope slows you down a little so that you can concentrate on what is important, now, rather than feeling like you need to skip over something to get things going faster. The health risk, the risk of death or creating something extremely unsafe are not only very real, but should be taken very seriously. You could harm or kill yourself, or others as well. And it wouldn't be that difficult to do at all. Please don't let money issues be the catalyst for you driving yourself too hard, too fast, and end up harming yourself.
