The U.S. Steel Corp. will conduct a test of emergency equipment Tuesday at Mon Valley Works, its facility in Clairton.

The test, scheduled to take place from 9 a.m. to 2 p.m., will involve sirens, lights and loud speakers that will be heard in the surrounding areas. A news release said the test could take up to six hours to complete.

“This annual test is performed to ensure that the plant’s emergency systems function properly, thus aiding efforts to protect the safety of our employees and the surrounding communities in the event of an actual emergency,” the release said.

Each emergency system will be activated one area at a time, with five distinct areas to be tested. No employee evacuations will occur and no local emergency responders will be present.
