Personal liability (piercing the corporate shield) is a really tough nut to crack. That’d also do some outsized harm- think kids college fund raided for settlement money.
That said, I’d be happy to make it a personal crime to, with knowledge of the law, instruct any worker to use a machine without safety equipment and water hookup, or to work without a mask. THAT should be a personal crime, like criminal charges. And you should have to, when hired for any such supervisory position, sign a one-piece thing that has that law laid out so you can’t claim you didn’t know the law.
