What is the difference in NYS between a fire investigator and a fire marshal ? Reason I'm asking is my county (95% volunteer) has fire investigators that fall under the Fire Coordinator. The other day at a structure fire, a fire investigator arrived in his POV using blue lights. All the Coordinators and Deputy Coordinators run red. I looked in the NYS VTL under emergency fire vehicle (Section 115) and it lists fire marshal. Is it one in the same ?
