GRAND RAPIDS, Mich. (WOOD) — Forest Hills Public Schools conducted an investigation to determine the cause of a bus fire back in November.
According to a letter from the superintendent, Forest Hills Public Schools initially removed nine other buses from service that were the identical make and model of the bus that experienced a fire in the engine compartment area on November 20. All of the students and the driver were safely evacuated and there were no injuries.
Since the fire, the school has conducted an extensive investigation to determine the exact cause of the fire. The investigations were conducted by the bus manufacturer, Thomas Built Buses, and by an independent firm, West Michigan Risk Management Trust.
Both investigations identified the cause of the fire as a failure within the power distribution module which showed electrical faulting or short circuiting on the circuit board.
The nine buses that were removed have had all of the power distribution modules replaced as well as the connecting cables and any other components that showed any signs of corrosion.
There was also a meeting held with school officials, the fire investigator, an electrical engineer, an inspector from Thomas Built Buses, representatives from Hoekstra Transportation Inc., and officials from West Michigan Risk Management Trust.
All parties gave the buses a “green light” and approved them for normal service beginning March 10.
