How to script equipment that cannot be unequipped?

[tenb1]

I was wondering if any of you script wizards out there know how to make a set of equipment unequippable temporarily

 

for example :

 

PC / companion NPC is captured and the jailor puts a special neck and wrist irons that cannot be taken off unless the escape quest is completed.

 

Also is it possible to set it so while these wrist irons are equipped, you can only equip certain clothes or armor on the PC/NPC like prison gloves/clothes?

 

thanks in advance!
