a. Before removing a module, ensure that you are at the same electrostatic potential as the
equipment by touching the case.
b. Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoid
touching the electronic components, printed circuit tracks or connectors.
c. Do not pass the module to any person without first ensuring that you are both at the
same electrostatic potential. Shaking hands achieves equipotential.
d. Place the module on an anti-static surface, or on a conducting surface which is at the
same potential as yourself.
e. Store or transport the module in a conductive bag.
More information on safe working procedures for all electronic equipment can be found in
BS5783 and IEC 147-OF.
