That is not correct. You can choose not to list a chemical even if it is hazardous if it is a trade secret. You still have to list the hazards, but not the actual name. Most companies would not be able to defend dichloromethane (methylene chloride) as a trade secret because competitors would be able to figure out what was in there based on the SDS and the smell. Plus you really aren't gaining a competitive advantage by using a chemical that is hazardous. The true advantage would be finding the chemical that works as well as dichloromethane without the toxic properties
Gotcha, but a perspective on Hendersonville and NC in general. You live in a very small part of our world so don't generalize about global warming etc everywhere else.
1. Hendersonville county, NC = 375 square miles.
2. NC total = 53,819 square miles.
3. Your environment = 0.7% of NC but it was a cold ##### there for sure.
