Companies were dispatched to a tractor trailer accident involving possibly hazardous materials on I 81 NB MM just prior to MM53. U133, first arriving from clearing a med assist call, reported one tractor trailer into the woods with the driver confined. E33 (in place of Squad 33) and Tanker 33 responded. The crew began making access with chain saws. R45 arrived and provided rescue tools to complete extraction of the driver. Manpower was supplied by E41 and E31. The truck was carrying welding type cylinders but there was no hazardous materials involved. Crews did have fluid leaks from the truck but unable to do anything with that. HJ Towing will be responsible for any cleanup and removal of the truck and trailer. Crews were on scene about 1 hour.
