La Salle residents told to shelter in place after possible explosion at Illinois chemical plant

A possible explosion has taken place at a chemical plant in LaSalle in Northern Illinois. A shelter-in-place order has been issued for residents in the area.

Firefighters arrived at the scene after a fire prompted a plume of smoke to rise above the plant, which has been evacuated, WGN9 reported.

The fire started shortly after 9am on Wednesday at Carus Chemical. The authorities sent an emergency alert to those in La Salle’s third and fourth wards to shelter in place.

The blaze has been classified as a 4-alarm fire, according to NBC Chicago.

La Salle police said an “explosion” took place in a shipping container at the plant, which is about 80 miles southwest of the windy city.

Carus, a family-owned business started in 1915, produces “supplies products and services for municipal water treatment, wastewater and air purification and soil remediation,” the company site states.

“There was a fire at the Carus Chemical Building. Residents living nearby are asked to please shelter in place,” the city authorities said in a statement.
