A chemical spill temporarily closed the northbound I-5 near highway 138 Wednesday afternoon.
The California Highway Patrol reported that bags of high calcium hydrated lime spilled over a 200-foot section of the highway.

One officer was exposed to the chemicals but was treated at the scene.

L.A County Hazmat responded to the spill but Caltrans finished the cleanup which took about three hours to complete.

According to Graymont.com, a company that manufactures lime, hydrated lime is used in a variety of industrial applications including water treatment, as an anti-stripping agent in asphalt, and in soil stabilization.
