While keeping safety in mind is a good idea, and to rigorously enforce it is commendable, I would urge against the use of the word "nazi" to describe it.
The Third Reich under the rule of the Nazis was one of the worst regimes in the history of mankind. Millions of innocent people died under their rule in complete and utter genocide, and to throw the word "nazi" casually into a non-historical context depreciates the real meaning behind the word.
A much better way would be to use something with a less negative and offensive background, like Safety Sergeant.
I sincerely [and pre-emtively] apologize if you perceive this as a personal attack, as it is anything but.
