ABSTRACT:
A system for abrasively cleaning surfaces such as by sandblasting and including a vacuum arrangement for recovering the material abrasively removed from the surface as well as the abrasive material is provided with a control circuit operable to actuate an alarm and/or deactivate the abrasive cleaning operation by sensing a drop in the vacuum pressure at the blast head which is indicative of an inappropriate positioning of the blast head and thus discharge of the abrasively removed material and abrasive material to the surrounding environment.
