An asphalt tank caught fire after an explosion at the United Asphalts plant in Commerce City, CO, Monday.
The fire broke out around 11:25 a.m. as the crew tried to heat the tank “to get the right consistency,” an Adams County Fire Department spokesperson said.
United Asphalts, founded in 1960 in Denver, produces roofing asphalt, including “no-smell” products that uses an odor suppressant.
Gregg Vest was working security detail at a nearby business when he heard a loud boom and ran outside and saw smoke coming from one of the tanks at the asphalt plant at 4306 E. 60th Avenue.
Vest snapped several photos of the black smoke emanating from the plant site.
Vest said he saw a crew member on a fork lift trying to control the blaze with a fire extinguisher.
There were no injuries in the incident.
