Does NFPA define "substantially career" fire department?
This link does a fairly decent job of describing how you might select and defend your choice if you are a combination FD: http://www.mtas.tennessee.edu/download/file/fid/46657
It doesn't appear there is any "official" NFPA definition of "Substantially" in the standard, thus select and defend seems to be a logical approach.
For example, our FD is a small combination department with 18 career employees and another 12-16 paid-on-call personnel. I'd say we're "substantially career" both in numbers and by requirements. The call division personnel are not required to maintain the same level of fire and EMS training as the career staff. I know of other places that the career staff pretty much drive and maintain the apparatus and the call folks are the actual firefighters, and most of the time the numbers are slighted in he other direction. Of course, if we had to comply, our municipal officials would scramble o find justification to call us primarily volunteer, given the financial burden of full 1710 compliance.
