Orcem boss says that his product is so benign that he will not require his operators to even wear respirators, while other companies who manufacture similar products state that their employees MUST wear respirators according to OSHA requirements. He will harm his employees or is trying to dupe the public.

Honestly, these “pro” project folks need to educate themselves a little more before shooting off at the mouth. They paint those of us who have been researching “the facts” of this project for the past 18+ months as though we are a bunch of crazy environmentalists who complain about everything. We are professionals in highly regulated industries who know what we are talking about and have seen first hand what happens in laboratory trials & analysis of the harm that certain chemicals and manufacturing processes cause in animals, humans and the environment.
