This morning Company 4,5 were alerted to the PA Turnpike for a reported tractor trailer on fire. While enroute, Turnpike Communications advised responding units of a working tractor fire with no involvement of the trailer section. C-40 advised to put Tanker 5 on the detail at that time due to the Turnpike not having it's own water source. Crews arrived and found an involved tractor fire with no hazardous materials in the trailer but with slight fire involvement of the trailer. Crews were on scene approx. 1 hour and turned scene over to PSP.
