A green substance started covering windshields and vehicles around La Salle, Illinois, Wednesday following a massive fire at a chemical plant in the area and officials are warning residents and drivers not to touch it.
The LaSalle Police Department released a statement telling residents in the area of the blaze to stay away from a green substance that was released "in the area" as a result of a fire at the Carus Chemical Plant.
"Attention LaSalle residents of the 3rd and 4th Wards," the update reads, "due to recent events, an oxidizer (which appears green in color) has been released in the area. Do NOT touch this substance. If you see this substance near or on your residence it can be deactivated."
The statement then goes on to instruct residents on how to deactivate the substance, saying "in order to deactivate it, you will need a 1:1:1 mixture of: 1 gallon water, 1 gall of peroxide, 1 gallon of vinegar."
The U.S. EPA was also called to the scene and had arrived around 2:30 p.m., the agency confirmed to NBC 5.
Residents reported the green substance rained down following the blaze.
"It literally looked like it was raining green food coloring," said witness Ronda Louis, who was driving on Interstate 80 when she said the substance covered her windshield. "I guess the best way to describe is almost a shamrock green that was coming down on the windshield."
People in the area could be seen cleaning their cars.
"In the beginning it was green, then the color turned brown," said resident Juan Torres.
