Government standards for MSDS are not very specific, they can be written many different ways. I am not sure there is even any specific order. There is a new standard that is coming out that may be more specific, although it is probably in conjunction with Global Harmonization and from what I have seen with the NFPA labeling it seems to be a step backward. So whatever is thought of these MSDS, it may not be relevant legally if they have all the necessary information, whether or not you approve.
