LABELS: Are labels applied neatly and straight? Do the label numbers match up with testing results?
PLUGS: Are plug tops being removed where possible and polarity/fuses being checked? In the case of moulded plugs, is the engineer removing the fuse holder and not just looking through the gap to identify fuse rating?
VISUAL: is the engineer checking the appliance body and the WHOLE CORD for signs of physical damage?
