Not all machines can be used with guards. Another engineering control is the lockout. Before any work is done on a machine or tool, it should be locked out and tagged, and its power disconnected. Some jobs can be redesigned to reduce the possibility of hand and finger injuries. For example, some machines could be redesigned to feed materials in automatically.
Workers have to understand the hazards in the work area and make safety part of their routine.
Follow all instructions for machinery and tools. Don't wear gloves, loose cuffs, rings, watches, or other jewelry when you work with machinery. Use a push stick, not your hands, to feed materials into moving machinery. Keep hands away from moving machine parts. Always cut away from your body.
