What is NFPA's policy/code on refueling mission critical portable diesel generators while engine is running?
Hi all: NFPA 37 applies to portable engines that remain connected for use in the same location for a period of one week or more per Section 1.3.1 of the standard. This applies to engines on generators. A closed pipe system for refueling the tank is a consideration for fueling the engine while its running. Respectfully, Milt Werner
