That's odd, because every one of the incidents you listed (they are not accidents) was the employers fault. They may have also been the employees fault.
Here's the deal, if you have lazy employees, those who don't wear PPE, take shortcuts, etc., then what is the employer doing about it? If the answer is "nothing" or the equivalent, then the employer does not value safety. I've worked at places where those things will result in termination or significant discipline and where they won't. Guess which places care about safety?
Finally, if your workers are taking shortcuts, then that implies that your assumptions about workflow are wrong. You are making people work too fast. Or your PPE sucks. In any case, once again, the employer is at fault. The employee is making a rational choice: lack of performance will get me fired, safety violations won't.
