PITMAN — When you start hearing sirens and seeing police cars zooming through Pitman Sunday morning, don’t be alarmed — it’s just a drill.

The emergency management drill and training exercise will involve police, the fire service, emergency medical services, pubic works, Gloucester County HazMat and a bomb disposal unit.

It’s just training, mandated by the state, and not an actual emergency. It starts at about 8:30 a.m. and lasts until noon.
