Can you run a fridge freezer off an extension lead?

Yes it will be fine, as long as you keep within the current ratings of both the main socket and the extension. As the current draw of the lights is minimal this isn’t going to be a problem. This is what extensions are made for, and there’s nothing particularly special about a fridge/freezer.

Does OSHA allow extension cord repair?

Answer: Extension cords used in construction may be repaired, so long as the repair returns the cord to the “approved” state required by §1926.403(a).
