My vol. dept currently has a 100' aerial with bucket. Also, we were recently issued Globe's G-Xtreme pants with internal (Class II) harness. I am wondering if it is possible to use our harness with a pompier hook/carabiner (ex: CMC ProSeries XL) instead of the Class I belts we have on the truck? Does anyone know of any NFPA standards that address this or have any other info?
