A truck carrying a chlorine-based chemical burned in southwest Mississippi Thursday.
The truck caught fire Thursday morning while headed southbound on Interstate 55 near Summit, MS.
A motorist warned the driver there was a fire under one of two trailers, said Mississippi Highway Patrol spokesman Cpl. Brandon Fortenberry.
The driver pulled off at the Lake Dixie Springs exit, but was unable to put the blaze out with a fire extinguisher.
A trailer of calcium hypochlorite, often used to chlorinate swimming pools, burned. Firefighters put out the fire before it claimed a second trailer.
A hazardous materials team from the Mississippi Department of Environmental Quality is cleaning up.
