I had a TV set with a touch sensor channel selector.
Every once in a while a fly would walk across the buttons, and change the channels. I guess the fly didn't like my choice in programming.
As hard as it may be to accept, it is not possible to design power tools and powerful equipment that nobody can get hurt on (by accident). How many injuries per year are acceptable? Zero if you are the person who lost body parts.
But the reality of our lives is that we control powerful machines everyday, for some people its all day long. If you take a zero-accident approach then everything has to be very expensive, time consuming to use, with double redundant safety features. ( the ultimate system would be fully automated, you have a stack of boards and the machine saws them for you, with no human intervention - you stand outside the perimeter guards and push the start button).
Even then, if you stop a person from sawing off his fingers they may very well step in front of a bus an hour later, choke on a hot dog, fall down the stairs, get struck by lightning, or hit by a marble size meteorite (or all of the above at the same time
)
I know there is a balance to be struck. To me it seems more reasonable to find ways to keep fingers away from saw blades, than to design saw blade/finger contact systems that jam blocks of aluminum into spinning blades.
We have to accept that emergency rooms will not be put out of business anytime in our foreseeable future. We should do everything reasonable to keep people safe from harm
but everything about this system looks wrong to me. Esp the fact that it is being mandated by lawyers and elected officials, not by people who work in the industry to ensure worker safety.
