Authorities say those workers were taken to the hospital with non-life-threatening injuries.
The fire happened at a company called Fox Valley Systems, a paint company that paints and stripes athletic fields and roadways. At about 1:20 p.m., the fire department received a call about an explosion.
Fire crews were on the scene when a second explosion occurred. By 6 p.m., the fire had been struck.
The front and back walls of the building were blown out. Flames and heavy smoke were seen coming from the building as firefighters tried to extinguish the fire. HAZMAT crews were also called in.
Between 25 to 35 nearby buildings were evacuated as a precaution, but officials say nobody was at risk.
Officials have not determined what led to the explosions.
Cary is about 45 miles northwest of Chicago.
