UPDATE, 6:06 p.m.: One patient and several EMS personnel had to be decontaminated after a crash and spill in Bushkill Township, according to Robert Mateff, the director of Northampton County Emergency Management Services.

Teams from Lehigh County Haz-Mat and the Department of Environmental Protection's Emergency Response Program were dispatched around 4 p.m. to the crash at Old Allentown and Male roads.

Early dispatches said police feared the vehicle was a mobile drug lab, carrying chemicals used to make methamphetamines, according to a report in The Morning Call.

Mateff would not confirm or deny these reports -- his main concerns were for the patients' safety and to make sure the scene was safe.

According to Mateff, when fire and EMS personnel arrived, the patient was covered in a substance similar to WD-40. That was when Emergency Management Services was dispatched to the scene.

One area resident was forced to leave her car at the Giant Food Stores in Wind Gap and walk to her house on Male Road, but there were no evacuations, Mateff said.
