Foul Odor Released After a Monument Sign Is Unplugged

We had a national veterinary customer ask us to remove an existing monument sign (manufactured and installed many years ago by another sign company). The sign was no longer permitted. We disconnected power and removed the sign, then received a call several days later. Turned out, the power for the sign was also connected to the freezer where they stored deceased animals. We obviously returned immediately and hooked power back to the freezer. The stench was awful.
