I was wondering if someone out there might be of some help, as I have misplaced my copy of the NFPA standard. Does anyone know what the nfpa recommendation for a ladder pipe hose is? I am wondering if single jacketed is acceptable for use in a ladder pipe for weight conservation or if I should be staying with double jacketed. This will be a dedicated 100 foot length that will never see interior work and minimal dragging. Any help would be greatly appreciated. Thanks
