Kellogg’s manufacturing plant was hit by two unrelated fire incidents within days last week, it has been revealed.

The first fire, on Saturday 11February, affected the Bran Flakes production line at the factory in Wrexham, North Wales.

The fire started on the roof in of the facility, and was thought to have been caused by a blockage in a cyclone dust collection system, causing a motor to overheat.

Three appliances attended the scene where staff were evacuated, but the damage was minimal – thought to be restricted to around 10% of the extractor unit – so production was able to resume the same day.

The second more significant incident happened just a few days later on February 13, this time on the production line for Elevenses cereal bars.

The fire broke out in an industrial oven used to bake the bars, causing a complete shutdown of production in this part of the factory. However, the fire did not mean a complete evacuation of the rest of the plant, meaning there was only minimal disruption to the cereal maker's output.

One appliance attended this second fire which was confined to the oven. Thermal imaging cameras were used to ensure the fire had not spread.

Production on the brand was resumed the following day, resulting in an estimated 10 ton reduction in output.

A kellogg’s spokeswoman told foodmanufacture.co.uk that they were not worried about the timing of the two fires.

She said “Anything that happens in our plants in investigated fully. Are we concerned about there being two [fires in a short amount of time]? No. But we are investigating fully.”
