Ingenious humankind has built numerous safeguards into tools and machinery used in modern industry, big and small, but those devices cannot protect one from one's own carelessness, as demonstrated by this movie's everyman, Wrong Way Butch, working in a machine shop. Butch is easily distracted or just isn't watching what he is doing when he should be focused on the use of the tool in hand. He chooses the wrong tool for the job, and wears inappropriate clothing. Even with those safety devices such as a lathe guard, he does not use them to protect himself. Without authorization, he uses machines which he has no idea how to operate and knows nothing of their working condition. He will take short cuts through restricted areas of the shop where hazards unknown to him exist. And he doesn't tidy up his work area leaving potential hazards for himself and others.
