Personal Protection Equipment is important in the workshop, but not every operation automatically warrants it. I didn't hang out in the classroom the entire time, but I did not see a single operation that would have caused me to automatically go reaching for safety glasses. I wasn't in the room when the RAS was being used, but this might be one of the more prominent exceptions. Possibly also the use of Kapex, but I wouldn't normally consider it myself.
Yes, I understand that there are some that believe safety glasses should be warn worn as soon as you step into a workshop, but that is not automatically held true by everybody. The same could be held true every time you step into the kitchen as well, since there is a risk of hot fluids splashing or popping, but you are not likely to see very many cooks wearing face visors or other PPE. Technically, every time I opened the lid on the smoker to check the status of the ribs or to stoke the fire, I should have been wearing a respirator. When I sliced the ribs into riblets, I suppose I should also have been wearing chainmaille gloves.
The lack of sawdust on the floor is testament to the low risk of projectiles and debris in the shop. When a cutter or moving component is fully encased within the body of a tool or within the body of a workpiece, I do not consider that to be a high risk operation.
