Things that people should know

Thanks for the great review Uriah!
I found the course a bit too basic. I should have spent more time exploring options before deciding on this course.I was looking for a more in depth explanation of codes and requirements suitable for someone with intermediate knowledge of the subject. The cost was minimal so live and learn.

Thanks for the feedback Matt! Our content on machine guarding and lock out tag out is mostly focused on safe work practices, so I'm not sure if there is another option with explanation of specific operation procedures. We do have some other options on safety that dive a little deeper on the topic.
