A conveying system includes a conveyor belt having a carrying-side cover plate for accommodating goods to be conveyed and a running-side cover plate free of goods. Each of the cover plates is made of polymer material having elastic characteristics. A drum engages the conveyor belt at one of the side cover plates whereat a spark can develop during operation of the conveying system. A device detects the spark and corresponds with an evaluation unit. The evaluation unit is configured to transmit a signal to a fire-extinguishing unit upon detection of the spark.
