We put 2 chairs in a high security prison called Full Sutton near York and it was a bit of a nightmare because the guests are mainly ISIS terrorists and murderers .
They were very conscious of the risks to the nurses so anything that was anywhere near considered sharp even something as inocuous as a eyewear arm had to be soft,cushions had to be breathable so no smothering,and no hazardous chemicals.
I think Peter Jones was involved with providing the machine and disposables.
Main thing to watch is you need to document what tools you need to take in with you and NO phones or memory sticks otherwise you might find yourself invited to stay for a while.
If you are being asked to provide costings think of a number and double it to take into account the time it will take you to clear security goig in and back out.
I think the best option would be to transfer the inmates to a unit already set up and running if there is one close enough or they can't have visitors anyway.
