wow, I can't even believe that such a question would be considered. The NFPA is a definite help to ALLLLL departments, whether volunteer or paid. Because whether you are volunteer or paid you still are doing the same type things. I've said this before to such a similar post, i believe ALL dept should be obligated to achieve the standards of the NFPA.
Id say friend, not every volunteer wishes to stay a volunteer. Many want to move on to paid firefighter and they need the training. As for those who do not want to move to paid, they still need the standards for safety and practice as a guide. Is they NFPA 100% accurate no, but it changes as new information appears to make every firefighter and the public safe.
