Jon,
In answer to your question about mixing chemicals for your personal use without having a MSDS. I am not an attorney and laws will vary from state to state. EPA regulations are federal and state controlled. EPA regulations are pretty much the same regardless of what state your in
This is a very gray area. Lets say for excample that you were doing a job and someone from the EPA walked up to you and asked to see your msds for the product you were spraying, What would you give them? You've taken one chemical and say you added two more, you have changed the chemical composition of all three of the chemicals so your msds sheets that you have for each chemical does not reflect the change. One thing for sure, if you have these chemicals mixed and transporting then, you best have a msds for that product (mixture). If you should have an accident and have a spill, your going to need one.
What I'm trying to say is as far as mixing your own at the job site, you may get away with it and you may not if you get caught. Depends on the mood of the agent who catches you. As far as transporting then, you will NOT get away with it if you have a spill and get caught.
A MSDS shows what chemicals are in a product and what % of each. It also shows if you are in complaince with the VOC regulations. The big thing is, if someone gets hurt or burnt with the product, the Dr./hospital will know what to treat for.
A person working on their own home or property is pretty much fee to do whatever they want to do, that is what I concider as "personal use". Being a contractor who works for other people is a whole different ball game and no longer falls under "personal use".
Sometimes it can get pretty scary and confusing being in business for yourself. If your mixing your own chemicals, check with your attorney to find out where you stand and what your liabilities are.
Just wanted to add this. If you got pulled over by the police and they found a bag of sulfer, a bag of patasium nitrait and a bag of charcoal, what do you think would happen to you if the officer knows his chemicals??? What would you say they were for???
