• Keep work secure – keep hands and other body parts out of the path of travel

Orbital/Belt & Circular Sanders

• Review what you will be working on, e.g. some painted surfaces contain pigmented paints that may create a significant air contaminant hazard. Assure proper PPE and that ventilation is specified and used.
• Metal objects – check work for objects such as staples or nails
• Dust bag – if equipped, ensure it is emptied frequently
• Prolonged use – break up work tasks to prevent overuse as vibration can cause injury to hands and fingers
• Sander – hold by insulated handles
