I have a question on how to interpret NFPA 414 Para 4.6.5 All-Wheel Drive. I have a small ARFF vehicle with only 300 gallons of water and complementary agent and is not 4X4 hence does not meet above stated paragraph. However Para 188.8.131.52 states: This requirement shall not apply to vehicles with a capacity of <1999 L (<528 gal). There are no other subheadings before this statement. However I have an inspector that believes this only applies to 4.6.6 All traction-increasing devices shall be operated by a single control for driving simplicity. So in NFPA it is written as such:
4.6.5 All-Wheel Drive.
All-wheel drive on these vehicles shall incorporate a drive to the front and rear axles that is engaged at all times during the intended airport service.
An interaxle differential shall be installed with automatic means or driver-selected means of differential locking.
All traction-increasing devices shall be operated by a single control for driving simplicity.
This requirement shall not apply to vehicles with a capacity of <1999 L (<528 gal).
I believe 184.108.40.206 applies to the whole subsection of NFPA 414 Para 4.6.5 All-Wheel Drive: because there is no other sub heading stating it is a new section within 4.6.5. any comment would be greatly appreciated.
Thank you Mark
