A Baton Rouge EMS ambulance unit was responding to a crash at Goodwood and E. Airport with lights and sirens activated when it was struck on the cab's passenger side by a pickup truck on Old Hammond Highway near Sharp Road, Wednesday, February 8, 2017, in Baton Rouge, La. No serious injuries were reported in the crash.

Two contractors were "potentially exposed" to a substance at the BASF plant in Geismar Friday while working outdoors and were treated at the chemical plant by first responders, then transported to the hospital for further treatment, a plant spokesman said.

Jolen Stein, director of human relations and communications, described the substance as inert, one that is not reactive with other chemicals.

BASF is investigating the incident, Stein said. 

The two contractors were doing maintenance work at about 11:30 a.m. Friday, outside one of the production areas, when they were reportedly exposed to the substance. 

There was no offsite impact or additional exposure outside, Stein said.
