Disciplinary action could be taken against two MetroSafe supervisors who failed to manually sound alarms during a tornado warning Monday.

A recently-completed report from Louisville’s Emergency Management Agency and Metro Government concludes that a combination of technical and human errors kept the civil defense sirens from sounding.

First, MetroSafe radios did not pick up tornado warnings from the National Weather Service. The warnings would have triggered the sirens. Second, the two MetroSafe supervisors could have manually activated the sirens, but did not.

The Mayor’s office says action against the supervisors could include suspension, and is under review.

A series of safeguards has also been put into place. Several pieces of equipment have been replaced, and all supervisors will now have weather alerts sent to their phones and e-mail accounts. The supervisors have also been re-trained on storm procedures and how to activate the warning sirens.
