Crews responded to a warehouse fire at 3:21 p.m. in the 20200 block of 80th Avenue South.
A driver for the seafood product company housed there saw smoke coming from the large, two-story concrete building, according to Kent Fire.
Firefighters from Kent and Renton found and quickly put out a fire in a first floor office.
Smoke removal was still underway, due to the size of the warehouse. The haze was being forced out of the building with large fans, according to Kent Fire.
Owners of the company were working with crews at the scene to determine the cause of the blaze, Fire officials said.
