Your understanding of manufacturing safety issues would greatly benefit from some experience in these settings. Safety is a big deal. That is why people are trained and kept uptodate through additional training on process and safety issues.
Your comment "...I don't want people in those critical positions who need training and I don't want my managers spending their time training them or ensuring they are doing their jobs properly." reveals much about your experience, understanding, and any character that you would develop from employment that produces finished products of value.
Your comment "... I believe the number would not be as high if people knew they would be held accountable for their actions, including mistakes. It's a zero tolerance policy, if you will. If that makes work "not fun" and is considered bad HR, then so be it." further blows my mind. Have you ever had to cooperatively work in a group with a goal?
Yikes! It's time to get a life beyond the keyboard.
