CARVILLE - A shelter-in-place order has been lifted from a chemical plant Carville after a Hydrogen Fluoride release around 12:45 p.m. 

According to Louisiana's Department of Environmental Quality, the Honeywell plant went into a facility-wide shelter-in-place until after 2:30 p.m. Monday. 

One person was exposed to the chemical and was treated on-site. 

LDEQ said the line that caused the leak is being depressurized and the facility's air monitoring has not detected any more chemicals in the air.
