Look
When checking power outlets we look at the controls to make sure it’s off and this is the only thing we look at for rest of system.
Lock
We’ll use the image of ice since the power outlet is electrical. Ice tells us it’s cold, so if it’s cold it must be off.
Label
With the power outlets, we use the image of a serrated knife to label this image to our body. Imagine a serrated knife suspended in mid-air carving out a rectangular section in your thigh (or whichever body part you chose to label to). Then imagine a large chisel is hammered into thigh removing the rectangular section in the process. The replica power outlet is drilled into that divot with two screws at each end. To finish off freeze that body part with the power outlet.
Leave
Seal off the area with the armor. Should you worry that you’ve accidentally left the outlet on just unseal your armor, feel that frozen power outlet screwed onto that cutout body part, then reseal it back over once you’ve eliminated your anxiety.
