I was reviewing FAA AC 150/5210-17C "Programs for Training of ARFF Personnel". Although NFPA firefigther certifcation is not required by Part 139 I am curious if other Part 139 certificated airports have their ARFF personnel certified under NFPA 1003. If your ARFF personnel are or are not certified under NFPA 1003 I am interested in hearing from you. What are the advantages and/or disadvantages? Thank you.
