Electrical Safety Checklist Power Cord Issue: Any Electrical Safety People Around?

Power cord issue: any electrical safety people around? - electrical safety checklist

I wonder about some electric son. I noticed a few scratches on the surface of electric cables that are exposed to intensive use. It is fixed now, but I want to make sure I'm safe. The material does not appear in the column or something more aesthetic (the glossy coating on the rubber was in one or two places.) Anybody here made familiar with electrical safety?
