Hand-held Circular Saw Kickback
A man was using a hand-held circular saw to cut a piece of wood when the blade encountered a knot. The saw kicked back but the blade-guard did not cover the blade in time, allowing the rotating blade to cut the man's free hand. The defense argued that the sticking blade guard became bent when the user dropped the saw. Through testing, we showed that the blade-guard had been manufactured with a bend, resulting in its sticking open before it covered the blade.
Table Saw Blade Contacts Operator's Hand
The promising career of a jazz musician ended abruptly after a table saw he was using injured his right hand. Dr. Ojalvo demonstrated to the court that it was technically and economically feasible to install a safety interlock mechanism, which would shut off power to the blade when the guard was removed. As a result, the jury awarded the Plaintiff $1.6 million in damages.
