Drillman,
OSHA is an ace in the hole on this one, but check out the ACA standards as well.
I worked at a large prison for 7 years (as a matter of fact, it was Lorton Prison and they shipped half our boys down your way when they closed down) and Correctional staff was NEVER allowed to reset.
They do NOT know how to check for fault, they are likely to close back into a fault and that will/could destroy equipment that may have been able to be repaired. IOW they have not been judged electrically qualified by your governing authority.
Suggest you try to find some videos on arc blast to convince him of the problem you may encounter with no experience in these matters.
That said, we used to let them reset NO MORE THAN a 20 amp breaker, and only once, then call us, and only off hours. Let's face it, they know if they just plugged a 1500 watt heater in 10 seconds before the breaker popped.
He is also placing the correctional staff in a precarious position. They may not want to go along with this program either.
Good luck
