Ya, if you don't have a chemistry degree, or perhaps a medical degree, SDS sheets will scare you to death. I worked at a USA research facility in the middle 90's and they required "MSDS" for every liquid. Well, I and friends could not resist, so we made our own for water. Everything on it was true, found in high concentrations in cancer cells, found in drownig victims, known as a greenhouse gas, known to impede breathing, ....... The reviewer called me in the office and said that chemical would absolutely not be allowed on the site. I asked him if he read the chemical name carefully (Hydrogen Dioxide) and did he know what the common name was? He arrogantly said yes, so I told him to remove the drinking fountain from all buildings ASAP.
By then he realized I had tricked him. He forgave me, eventually.
The point is that most of what you read on SDS sheets (the M was dropped a few years ago), is meaningless without the knowledge of how to understand and apply it. Good reads, but common sense and some practical knowledge is often necessary.
