When I was hired as a contractor at NREL, we had 2 days of safety training. Which is far more than I've ever had anywhere else. Everyone I worked with was an engineer: many had masters and PhDs (the product I worked on started as the dissertation of our group's leader).

We used to make fun of some of the videos giving them titles like "rattlesnakes are not your friend" or "you and your fire extinguisher" and the most entertaining "do not look into laser with remaining eye". People in Colorado are very outdoorsy, and unfortunately, rattlesnake bites were not that uncommon as there were lots of rattlesnake dens on the campus.

TL;DR - the workforce at the national labs tends to be highly educated and trained.
