ABSTRACT:
A shredder is disclosed having a gas detection system. According to one embodiment, one or more sensors may be placed inside the housing of the shredder to detect the presence of gases, and in particular, flammable or combustible gases. If a gas is sprayed into the shredder, the sensor(s) will detect the gas and the shredder may be deactivated. In addition, an exhaust fan may also be activated to purge the gas from the housing. Further, one or more indicators may be provided to alert the user that the sensor has detected gas. For example, a visible signal and/or audible sound may be generated to alert the user that the sensor has detected a flammable or combustible gas.
