Hi, my name is Karen. For years I ran the HR department in a processing and manufacturing plant. Unfortunately, I also had to deal with several issues related to people getting hurt through the use of chemicals. I felt so bad for them that I made it a point to start researching different chemicals used in the manufacturing process, and I discovered ways to choose safer chemicals and to refine the manufacturing process as needed. I no longer work in that field but am still interested in learning and thinking about it. If you want to read about chemical safety, please take a look at these posts.
