      an appliance is not defeated.

12. Power-Cord Protection

 - Power-supply cords 

      should be routed so that they are not likely to be 

      walked on or pinched by items placed upon or

B.  Objects have fallen into the appliance; or

C.  The appliance has been exposed to rain; or

D.  The appliance does not appear to operate normally 

      or exhibits a marked change in performance; or

E.  The appliance has been dropped, or the enclosure 

      damaged.
