While using hand tools, try to keep your wrist straight and avoid any awkward motion of hand tools. Though, the basic guideline is - Carry all sharp tools in sheath or holsters. Tag worn, damaged or defective tools “Out of Service” and do not use them. Do not use a tool if the handle surface has splinters, burrs, cracks or splits. When handing a tool to another person, direct sharp points and cutting edges away from yourself and the other person. Do not carry sharp or pointed hand tools such as probes or knives in your pocket unless the tool or your pocket is sheathed. Do not perform “make-shift” repairs to tools. Do not throw tools from one location to another or from one employee to another. Transport hand tools only in tool boxes or tool belts.
