Related to the  Design  of Tools and Equipment:

1.        The hands should  be relieved of all work  that can  done more  advantageously by a jig a  fixture  or a foot operated device.

2.        Two or more tools  should be combined wherever possible.

3.        Tools and materials should be pre positioned wherever possible.

4.        Where each  finger performs some specific movements such as in typewriting  the load  should  b e distributed in accordance with the  inherent capacities of  the  fingers.

5.        Handles such  of as those  used on cranks and large screw driers  should  be so designed as  to  permit as much  of the surface of the hand  to come in contract with the handle as possible .

6.       Levels  crossbars and hand wheels should be located such  positions  that  the operator  can  manipulate them with the greatest mechanical advantage.
