    Sharpening of hand tools

    PHOTOS TASK HAZARDS CONTROLS

    Using a rasp to sharpen variety of shop tools

    Cuts, puncture wounds, eye injury

    Always use two hands while filing. This prevents the tool from bouncing off the work bench and onto the worker. The flat edges of the file or rasp are sharp enough to cut skin. Never use a file or a rasp without a handle. The pointed end can puncture or lacerate the skin. Use the file in one direction only. File away from the body to prevent injury. The teeth of the file are generally facing one direction. To file against the teeth will cause the file to bounce off the work material and injure the worker. Wear safety glasses to prevent particles in eye.

    Whetstones are used

    to sharpen knives,

    scissors, and other

    flat-bladed tools.

    Cute, Puncture wounds, eye injury

    Always keep hands and fingers clear of the area of the stone where the tool is being sharpened. Secure the whetstone before sharpening a tool in order to prevent slippage. Wear safety glasses to prevent eye injury.

    A grinder is a piece of power equipment used to abrasively remove

    Serious injuries from a loose-fitting or unbalanced wheel which
