Mindy is spot on, from my view. I would just add that it does not hurt to explore options, as there may be a solution there which will work for all concerned without sacrificing safety. We want the residents to know that at least we tried. The effort to get educated over this can help for future situations of the same.
When there was a situation that I had not ran into before I started making phone calls and talking to fellow professionals as well as the offices and departments that were concerned to try and findout answers. When I was in the military, I had this commander, who challanged his officers with, "Do not tell me why I cannot do it, tell me how I can do it." So, it was a mindset of always looking for options.
The options may mean that the resident may have to go in their pocket, and it may boil down to you cannot fix it, and I always say safety outweighs everything else. That is why I suggested talking to your locals to see what ideas are out there and if none are found, then at least you tried, like getting on here. Wish this site was here when I first started out!
But, again Mindy made it short, sweet, and too the point!
