Lafayette General Medical Center will conduct a drill Wednesday morning to test its response to large groups of people exposed to hazardous chemicals.

“The public is asked to be aware of this event … so as not to cause any concern with sights and sounds occurring around the hospital that day,” the hospital said in a release.

The drill will run from 9 a.m. to noon and will not disrupt hospital services, the hospital said in the release.

Louisiana requires hospitals to conduct annual drills to prepare for emergencies and disasters, including a large number of patients being exposed to harmful chemicals.

“Given the large presence of petrochemicals in Louisiana, a mass exposure to hazardous materials through chemical spills is a major concern for health care providers and response teams across the region,” the hospital said.

Multiple agencies will take part — police, firefighters, hazardous material responders, public health officials and other hospitals.
