The tools used should be hand-held and not power driven because the person's control of the power tool is not dependable.
People who have a history of using power tools often try to get by with procedural memories, which is risky. Table saws and band saws can remove fingers. I have terrifying memories of trying to supervise the use of power tools in a woodshop. The scary part was the speed in which an accident could happen. Prevention kept me in a constant state of high alert during a session and relieved and exhausted by the end. Finally, I had to acquire the guts to ban certain people from the woodshop.
The stereotypical macho male, functioning within ACL 5.2, should be attracted to dangerous power tools. The truth is that they did not turn up in my practical experience very often. When they do, the secondary effects and needs for precautions may be acknowledged, repeated and agreed to verbally, but their compliance is not dependable. The situation with power tools within ACL 5.2 and 5.4 gives meaning to the phrase of an accident waiting to happen.
Power tools were standard equipment in occupational therapy clinics. But they are gone or locked up because they are too dangerous. The public is safer, but therapists have been spared the experience of being terrified by their impulsive use. We old-timers, who got scared to death, know, down to our toe nails, why they have trouble holding a job for more than two weeks. We would fire them too if we were liable. Try not to underestimate the dangers.
