To stay safe around electricity, Ted needs to C) Make sure electrical hazards are resolved immediately.
Following his gut instinct isn't always the best, because Ted might not be very experienced with electricity.
Procedures established by his co-workers aren't official ways of staying safe, they are just ways his co-workers have found helpful.
Practicing electrical safety only when his employer is watching isn't good, because if his employer wasn't watching then Ted would be in trouble. He wouldn't have his employer helping him with electrical safety.
