Kent Fire and Rescue Service were called to Medway City Estate in Strood at 10:31 this morning after a metal shredder at a scrap yard caught fire.
Five fire engines and 20 fire fighters were called to the scene.
Firefighters had to use special breathing apparatus to combat the fire, as the thick black smoke spread across the area.
Local residents were urged to close all doors and windows to keep the thick black smoke out of their homes.
The fire has now been put under control and Kent Fire and Rescue Service have reassured residents that they do not have to keep their doors and windows closed anymore.
