More than 35 firefighters have been tackling a huge blaze through the night at the Sundown Products factory site in Huntingdonshire.
Cambridgeshire Fire and Rescue Service was called at about 11.15pm yesterday (Wednesday) to Station Road, Tilbrook.
Fire engines from Kimbolton, Huntingdon, St Neots, Sawtry and Yaxley were sent, along with others from Bedford and Kempston in Bedfordshire and Thrapston in Northamptonshire.
A fire service spokesman said multiple buildings were alight and they contained cylinders of chemicals such as CO2.
Water carrier vehicles had to be called in to help fight the fire.
Fire crews remained at the site this morning.
