Fire crews dealt with a fire and chemical leak at the Vitec Videocom factory in Bury St Edmunds this morning.
One appliance from Bury St Edmunds was mobilised to an automatic fire alarm at the Western Way factory just after 4am. On arrival crews asked for more appliances due to a suspected chemical leak in the building.
Two more appliances from Bury St Edmunds, one from Elmswell and the Command unit and support pump from Ixworth were sent to the incident.
Crews used four breathing apparatus, one dry powder extinguisher and one hosereel jet to extinguish a fire on the ground floor.
They then ventilated the building, using a positive pressure ventilation fan and contained a spill on site.
Suffolk Fire Service said later that the cause of the fire had not been confirmed.
