U.S. Steel will test emergency equipment at its Clairton Works on Tuesday, a spokeswoman said.
Meghan Cox, manager of corporate communications, said the plant will begin testing sirens, warning lights and other alarms at 9 a.m. and continuing until 1 p.m.
Local agencies, including Clairton police and fire departments and Allegheny County 9-1-1, have been notified of the tests, she said. The tests may be audible in Clairton as well as surrounding communities.
Cox said U.S. Steel tests emergency notification systems once per year "to protect the safety of our employees and the surrounding communities in the event of an actual emergency."
There are five areas in the Clairton Works where emergency systems will be tested, she said, and the test may take up to five hours to complete.
No actual evacuations will be occurring, Cox said, and no fire or police personnel will be mobilized.
