Firefighters were called to the Perdue Grain facility in Chesapeake, VA on Wednesday afternoon after a large blaze ignited in a four-story grain drying tower at the site, several local news organizations reported.

Crews responded to the site at about 1 p.m. after receiving notification of the fire and observed thick smoke and flames in the facility’s grain drying tower, coverage by television news station WAVY said.

“Fire was located in a tower designed to dry soybeans. This was a labor-intensive operation involving multiple high-rise lines and a ladder pipe,” the Chesapeake Fire Department said in a Facebook post.

Workers evacuated the facility during the incident and the fire was brought under control by about 4:40 p.m., according to CBS News affiliate WTKR.  

No injuries were recorded during the incident, reports said. The cause of the fire is unknown.
