A food ingredients factory erupted in fire Wednesday evening in northeastern Spain, local media report.
At about 6:20 p.m., firefighters were summoned to the Dallant factory in the Baix Llobregat region of Catalonia. Workers were quickly evacuated from the facility.
Firefighters soon traced the source to fuel tank near the center of the plant. They were initially unable to enter the burning factory due to the threat of a roof collapse, officials said.
Responders instead concentrated on protecting nearby exposures.
Nearly 40 fire crews responded to the scene, including teams from Bombers de Barcelona. Even with the added personnel, firefighters expected to work through the night into Thursday morning.
Ambulance personnel report no injuries at the scene. Although no air quality monitoring has been necessary, residents have been warned to shelter in place.
