Temporary power is still power. The cord has to be rated for where it is, checked before it is used, and taken out of service the moment it is damaged.
Temporary gets treated as informal. It is the same voltage, in worse conditions, on a floor people walk on, and the cord that has been in the van for three years is the one nobody looks at.
Put a sound cord next to a damaged one and the difference is obvious: intact jacket against a jacket broken open with conductors showing. The reason the damaged one keeps getting used is that it still works. It powers the tool, so nothing announces the problem until somebody touches the right spot in the wrong conditions.
Check yourself: The damaged section is wrapped in tape. Is the cord back in service?
Answer: No. Tape over damaged insulation is not an automatic approved repair.
Tape hides the damage; it does not restore what the jacket was doing. The cord's insulation is a rated part of the equipment, and covering a breach is not the same as repairing it to that rating.
