Eastman Chemical Company will conduct an annual emergency preparedness drill at its Kingsport site on Saturday.
Eastman says the drill will take place from 9 a.m. through noon at the Toy F. Reid Employee Center off Wilcox Drive.
People nearby may hear sirens or see emergency vehicles participating in the drill. The company says there is no cause for alarm.
The drill will involve Eastman personnel and area emergency responders.
Last week, Eastman said it was investigating the volume of one of its alarm systems after it was triggered by a faulty sprinkler valve.
