It is the Schools and the teacher’s responsibility To see that the equipment is in good safe operating condition. You should contact the local School Board, State Education Board, OSHA and possibly the State Attorney General if need be to keep others safe. The teacher evidently is negligent in his attitude towards his students safety. It sounds as though maintenance is a very low priority on the part of the school system. What we do in our own shops is one thing, but it a community type shop, safety and maintenance is vital for all users.
Which is probably why so many schools are doing away with shop classes. Give the teacher an F for failure of safety and yourself an A for thinking of safety first.
