While true initially the HPR then is replaced next year by Billy Bob Joe's
Insurance and they sue the contractor when it fails.  HPR didn't legally
engineer it as they are not the EOR usually even though they often drive a
design, Codes don't cover it.  You are out on your own at that point.
"proceed very cautiously" is very wise.

  If the HPR insurance company makes a judgement call on how to  
protect it and it doesn't work, they pay for the loss.  IF this  
guidance is not in the published HPR Loss Prevention Data sheets, then  
the consult is making the judgement call.  Guess who will likely pay  
for the loss?  Now here's the scary part. If the contractor takes the  
responsibility and provides the judgement  call (typically considered  
consulting/engineering since guidance is not in 13 or other national  
standards) who will likely pay the claim?

The moral of the story is when NFPA 13 does not address it, proceed  
very cautiously.
