Machine guards provide a physical barrier between an operator and the hazardous points on a machine. They prevent accidental injury and protect operators from flying debris, contaminants, and noise. Machine guard configurations such as lathe guards include a visor to protect operators from flying debris. Drill machine guards and boring guards may include telescoping cages, barriers and bollards to prevent personnel from contacting machinery or entering dangerous areas. Consequently, the selection of a drill machine guard or boring guard is an important safety consideration.
