Chemtool Factory In Illinois Still Burning After Fiery Explosion

Evacuation orders remain in effect this morning as a fire still burns in northern Illinois after an explosion at a chemical plant.

The explosion sent a huge ball of fire and thick black smoke into the air.

The smoke could be seen as far as 100 miles away.

Emergency officials say it happened Monday morning at a Chemtool factory, the country’s largest grease manufacturer.

Investigators still don’t know what trigged the explosion, but all 70 employees working at the Chemtool plant made it out safely.

Everyone within a one mile radius of the plant in Rockton was ordered to evacuate.

Fire crews say the fire could burn for several days.
