Some TMI alert sirens don’t work on first try

LANCASTER, Pa. (AP) — All warning sirens in one central Pennsylvania county failed to work properly on the first try during annual testing of emergency alerts for the Three Mile Island nuclear power plant.

Officials say the 16 Lancaster County sirens did not sound on an initial test because county emergency workers hit their test button at the same moment as workers in another county.

The problem was quickly discovered but the county emergency management department decided not to sound the alarm 10 minutes late. Instead they notified local media the test would be delayed an hour.

The sirens worked properly the second time around.

County emergency management director Randy Gockley tells WGAL-TV the problem is being used as a “learning experience.”
