Firefighters were called to the Nestle Factory last night (Tuesday).
Two appliances went to the factory in Albion Mills, Halifax, at 10.30pm after reports of an overheated heat meter.
The crews used thermal imaging cameras to work out what had overheated and ensured everything was off. They then left the incident in the hands of Nestle’s working team.
They left the scene just before 11pm.
Nobody was injured.
