After 20 years teaching woodworking to kids using power tools of all kinds and working with progressively younger ones each year I had the Heath and safety branch of the local board of education,first tell me the kids couldn;t use the tools and afew days later (in the middle of a 12 day project)that I couldn;t use the tools. One large aspect and benefit of this project has been to teach safety,in the midst of danger.Litigation for the Nation.
