Welding students have been assisting the Maintenance Department at the Excelsior Springs Job Corps Center to help improve their classroom. The students have worked with the Maintenance staff to improve the exhaust system that takes smoke out of the classroom. The way it was previously installed, the smoke would by-pass the intake vent and the result was that the classroom was very smoky. None of the materials needed to be purchased. The project was able to be completed using existing scrap material.
