The fire broke out around 4:30pm at Rilco Manufacturing off Brittmore Park near Ashley Court. Authorities say it's an industrial complex where pipe insulation is made and it houses hazardous marterials, such as polyurethane foam and isocyanate.
From SkyEye HD, flames could be seen coming out of the side of the building and spreading onto piles of wood outside.
The blaze seems to have started on the southeast side of the facility, but spread throughout the building.
Firefighters from the Cy-Fair, Jersey Village and Houston fire departments, as well as a Harris County HazMat team, are responded to the fire.
The one person who was transported to a hospital was being treated for smoke inhalation.
